  Beyond the Quest for the Perfect Uppercase Partial Differential

16 May 2019
David Berlow — TDC/Google
[1:52:01] The last 30 years have seen a great growth in the possibilities of how typefaces can function. TDC medalist David Berlow illustrates his quest for the perfect, scalable, variable letterform, and the challenges faced servicing the ever-expanding, multi-lingual media world. Berlow discusses the design of glyphs over a range of sizes and weights, and how the designs can be specified to work together in web and print environments. He also demonstrates and describes inter-script, inter-class and inter-style typography, and concludes with a question-and-answer session.

  Bringing Language to Life: Isabel Lea, the girl with the dancing font

14 March 2019
Amy Papaelias — Adobe Create
Isabel Lea (whose LOUD variable font experiment got 1.6K likes on Twitter) didn’t expect to fall down the rabbit hole of variable font technology. But since the London-based graphic designer started the Adobe Creative Residency in May 2018, she's repeatedly found herself at the intersection between technological experimentation and typographic innovation.

  Variable Font Collections

1 February 2019
Ken Lunde — Adobe
This is a short article that is simply meant to draw developers’ attention to three OpenType/CFF2 Collections (aka Variable Font Collections) that I built this week, which are now available in the open source Variable Font Collection Test project. As stated in the project, the purpose of these Variable Font Collections is to simulate the Source Han and Noto CJK fonts deployed as Variable Fonts, to help make sure that the infrastructure—OSes, apps, layout engines, libraries, and so on—will support them.

  Enhancing the On-Screen Reading Experience With Variable Fonts

30 January 2019
Bianca Berning — Shopify Partners
Until the digital age, typography had evolved alongside our means of communication, with typographers primarily concerned with creating as good a reading experience as possible. But printed text is inflexible… with few exceptions, web typography is less accommodating than print typography … To improve the online reading experience, OpenType Font Variations, better known as variable fonts, have been introduced … improved web performance and greater typographic flexibility … As variable fonts are now supported by all major browsers, there is the potential to start using this technology already to improve general standards.


  18 = 96

17 November 2018
Akiem Helmling, Bas Jacobs (Underware) — Dynamic Font Day, Munich
[53:43] Dynamic Fonts (like OT 1.8) relate to tradtional fonts, like the web does to printed matter. Just like with the internet, it’s not the technologies themselves which matters but above all the consequences they imply. Meanwhile we all noticed that HTML, CSS & Javascript are not the web itself, but just technologies helping us to realise the bigger underlying idea: the dynamification of information. The same applies for OpenType 1.8. Just like HTLM, also the latest version of OT is not a new idea as such, but a new technological standard embedded withint an idea: the dynamication of the written word. A highly delicate situation where language itself is becoming variable. Where 18 is 96.

  Breaking Boxes – Type and Augmented Reality

17 November 2018
Andrew Johnson — Dynamic Font Day, Munich
[26:38] As a key component of any graphical interface, typography often finds itself in new spaces. The current landscape of Augmented Reality and sensor enabled displays give us unique ways to think about how we interact with type and information. Here, we can apply variable font concepts to make typography more adaptive to us.

  Movable Type Vol. 2

17 November 2018
Irene Vlachou — Dynamic Font Day, Munich
[27:22] Variable fonts are a delayed and versatile technology that confuses users and fontmakers. Typographers have to unlearn what they’ve learned and change the way that they design, use and teach type. A rough guide for a variable-savvy era and how you can survive, thrive or simply avoid it.

  Typeface personality + variable fonts

17 November 2018
Rasmus Michaëlis, Torsten Lindsø — Dynamic Font Day, Munich
[18:31] What are the possibilities of a variable typeface? Recently, Rasmus Michaëlis and Torsten Lindsø have explored how a typeface could respond to sound for Chinese audio tech company Goertek. Through variable font technology, the design team made the letters sound sensitive to their surroundings. Placed on signage throughout Goertek’s R&D hub in China, the design will assist in way-finding and express the brand. Typefaces’ branding potential will only grow as it is combined with the evolving potential of the digital world and the variable font format creates new possibilities for bringing in elements into the design from outside the world of letters. Rasmus and Torsten will discuss the opportunities of a variable typeface in the perspective of branding supported by projects and sketches.

  Variable Fonts and the Future of Web Design

8 November 2018
Mandy Michael — dotCSS
[19:17] The web is entering a new era of design opportunities with the introduction of CSS Grid, Photoshop like effects such as filters and blend modes and importantly the increasing support for Variable Fonts. Variable fonts can offer practical and creative opportunities for web design. We can combine them with pre-existing technologies to improve our font performance, design, accessibility and usability of our websites. We can also begin to explore new and exciting creative opportunities for story telling, design and expression in ways standard fonts could never provide us. This is just the beginning of our journey to discover what we can do with variable fonts. [slides]

  Implementing a variable font with fallback web fonts

29 October 2018
Oliver Schöndorfer —
With variable fonts, more typographic richness and influence is coming to the web and this at a relatively low file size. You want to benefit from that in your next web project, but still, you don’t want to bet everything on this new technique? This article will show you how to integrate a variable font in your website and use classic web fonts as a fallback.

  Firefox Web Inspector: Fonts tab

23 October 2018
various authors — Mozilla MDN
Firefox 63 adds support for editing the properties of variable fonts in the Font Editor. If the inspected element uses a variable font, the Fonts tab shows the axes that have been implemented for that particular font, providing control to alter the value of each one. This is very useful for quickly finding out what axes are available in a particular font — they can vary quite dramatically as font designers can implement basically anything they like. You can adjust the axes individually or, if the font designer has included defined instances, you can select one from the "Instance" drop-down list and view the updates live on your page.

  Are variable fonts the future of web typography?

21 September 2018
Bram Stein — CSS Minsk JS
You may have heard about variable fonts and how amazing they are (or not, in which case you should attend this talk!). But what exactly are variable fonts, and why are so many people excited about them? Is it because they offer exciting new ways to animate type? Or to endlessly tweak your typography? Or are they the answer to all your web font performance problems? Let’s find out!

  Introducing the first variable font – from 1793

15 September 2018
Petra Rüth — ATypI Antwerp
[16:44] In the late 18th century, C. G. Roßberg, a German clerk, worked on a stunning project: he envisioned a system of scripts which would harmonize together. Following the Renaissance approach, where science and art were intermingled, his aim was to encapsulate the beauty of letters in a mathematical system.

  Confessions of a variator

15 September 2018
David Berlow — ATypI Antwerp
[42:14] The last 25 years have created what I think of as the fog of modern typography. Now the combination of existing technologies, and new Technologies are spreading a whole new level of quality, functionality and performance over the foggy old system. While not directly breaking from the old, the new technologies allow us to clear the fog, get back to our roots and/or move forward to a whole new tradition. This leaves a lot of questions about the past, present and future, right and wrong, good and bad. This will be a presentation of what one type designer is doing about it.

  Hi HOI

14 September 2018
Sami Kortemäki, Akiem Helmling (Underware) — ATypI Antwerp
[37:19] HOI is the abbreviation of Higher Order Interpolation. By introducing this new perspective for font interpolation we can do things not achievable with traditional linear interpolation. HOI is a simple and “ready-to-use” solution to fully control our manually designed masters and interpolation. HOI is not only expanding the field in which fonts are designed and exist, but also questions some foundations of type design: like the concepts of design-space, masters, locations, and interpolations.

  Digital Legacies: A lifetime of type design tools, formats and projects

14 September 2018
Adam Twardoch — ATypI Antwerp
[22:31] The history of outline font editors spans some 40+ years, or the total of this speaker’s life. Ikarus, Pika, Fontographer, RoboFog, Type Art, FontStudio, TypeDesigner, FontLab, RoboFab, FontMaster, RoboFont, Glyphs, FontCreator – since the inception of outline-based font creation, type designers have employed a flurry of computer applications that have aided them in the development of type. … The tool makers came, went, or continued to reinvent. … In this talk, we will revisit some old and new type creation apps running on operating systems extinct and alive, including some of your [variable] favorites.

  Adidas Variable Font

12 September 2018
Jeremy Mickel, Leon Imas — ATypI Antwerp
[22:22] Variable Fonts show great promise for the future of typography, but have had few commercial applications. This is likely due to limited support in design programs, confusion about how the format can be used, and typical lag between the introduction of new technology and widespread adoption. Adidas has partnered with MCKL to create an innovative suite of variable fonts. These fonts are being used across a wide spectrum of applications, including Creative Direction, Product Design, Graphics, Communications, Digital Experiences, and the brand campaign for the upcoming World Cup. MCKL founder Jeremy Mickel will tell the story of his long collaboration with Adidas, which started in 2012 and includes the 2015 expansion of the Adineue PRO family. In 2017 they started the first Adidas Variable Font, Adineue CHOP variable: an octagonal “athletic” sans in a wide range of weights from hairline to black, and widths from extra-condensed to extra-wide. The next iteration of the project includes Adineue PRO variable, based on the geometric Adidas brand font. This talk will include discussion of the design process behind collaborating with Adidas, the production headaches and surprises associated with new technology, and the final payoff of seeing the fonts used in exciting ways.

  The problems that need to be solved when developing Chinese Variable Fonts

12 September 2018
Jeff Wu, Edwina Lee — ATypI Antwerp
[17:09] There are about 28,000 Chinese characters that need to be designed. The average number of strokes in a Chinese character is 12. In Arphic JingXi Hei, for example, the average number of control points for each stroke is about 100. Therefore, there are about 33,600,000 control points to deal with when developing a Chinese typeface. When creating a Variable Font, the control points of every pole of every axis need to correspond, so it’s a huge work to design, test the transfer to a Variable Font, and fix the design and control points. In this talk Jeff Wu shares the problems he met in developing Chinese Variable Fonts and how he overcame them.

  The state of the spec

  Variable fonts guide

31 August 2018
Jason Pamental — MDN
Variable fonts are an evolution of the OpenType font specification that enables many different variations of a typeface to be incorporated into a single file, rather than having a separate font file for every width, weight, or style. They let you access all the variations contained in a given font file via CSS and a single @font-face reference. This article will give you all you need to know to get you started using variable fonts.

  Yes, But Can Variable Fonts Do This

5 August 2018
Rainer Erich Scheichelbauer — TypeCon
[21:42] Variable Fonts are the latest craze. But can you have fun with them too? You bet. Let Rainer take you on a quick tour through the fun side of OpenType Variations. Like in his infamous Denver presentation about OpenType features, there will be no prepared slides, all typing will be done live.


4 August 2018
Akiem Helmling, Sami Kortemäki (Underware) — TypeCon
[20:50] The major challenge of type design in the 20th century was how straight lines could become curves. With fonts becoming variable, the same problem just arose again. Only this time it’s not about the outlines, but about the interpolations, creating those outlines.

While most type designers are working with interpolation based design-spaces to design large families or even Variable Fonts, there still seems to be a limited conception of the possible meaning of this ‘design model’. There is for example the strange contradiction that while type designers know exactly that stretching form is a bad idea, they are accepting that linear interpolating manually designed masters is exactly doing that for all the weights in-between. No matter if this interpolation is used for generating static fonts, or within a Variable Font. And while un-wanted results could be fixed manually afterwards for static fonts, there is no afterwards in the realm of Variable Font.

Despite the potential risk of getting intimidated by advanced technology, the real problem may not lie so much in the technology itself, but in the way we use it to define and create our ideas. Instead of thinking through technology, we could also reverse this process and make the technology think for us.

So what is a design space actually really about? And what if there is no space at all?

  Weird things variable fonts can do

20 July 2018
Chris Coyier — CSS-Tricks
I tend to think of variable fonts as a font format in which a single font file is capable of displaying type at near-infinite variations of things like boldness, width, and slantyness. But things like boldness, width, and slantyness and just a few of the attributes that a type designer might want to make controllable. There are no rules that say you have to make boldness a controllable attribute. Literally, anything is possible, and people have been experimenting with that quite a bit.

  Transform your type online with variable fonts

18 July 2018
Richard Rutter, Oliver Lindberg — Creative Bloq
Typography on the web has come a long way. About a decade ago it was still woefully underused and done very poorly – damaging user experience. … People were throwing their hands in the air, claiming you couldn’t do typography on the web well. … But there’s one man that has been trying to convince people otherwise and that's Richard Rutter … One of the biggest game changers right now is the advent of variable fonts, a technology that enables a single font file to behave like multiple fonts.

  Font Playground

  Is the future of Variable Fonts stuck in the licensing past?

5 July 2018
Johannes Neumeier — Underscore
Variable Fonts are an exciting step into a direction that is inherently embedded in modern type design technology. With user adaptation it will become more clear what are the use cases and market for this new format, but for now, most of the conventional font retailers are scrambling for viable licensing and pricing models that are bound to increase, not inhibit, the spread of Variable Font usage. So far type designers and foundries have been more concerned with the how and when of Variables Fonts, but one of the largest implications of this format is neither technical nor creative: Giving users control over the entire family span of a typeface prompts redefining what a font is, and what is the value it brings to customers.

  The evolution of typography with variable fonts: an introduction

17 May 2018
Jason Pamental — Medium
While variable font technology is still maturing and type designers are working to become more fluent in this new way of working, the promise for design on the web is ground-breaking. The typical scenario would be to constrain any given design to 3–5 different fonts to represent every aspect of a site’s design language and voice — including every permutation for body copy and headings. At its simplest implementation, variable fonts would give us the freedom to use different weights for every level of heading — greatly increasing their clarity and readability … the entire typographic system could be designed to be proportional: weight and width could become multipliers on the standard body copy settings. Doing so would allow those aspects to scale easily along with the body copy should its settings change based on screen size or user preference. All of this with an accompanying increase in performance due to fewer HTTP requests and an overall savings of data.

  Visualizing design space in variable fonts

15 May 2018
María Ramos — Alphabettes
“Visualizing the design space of a variable font in our 2D screens can be tricky. Our imagination can take us far, but decoding a figure with more than 3 dimensions is still a difficult task for our brain.” María presents a spider diagram approach that in principle handles an unlimited number of dimensions. It’s similar to Petr van Blokland’s proposal of behaviour needles, but with the default at the centre (hence the possibility of self-intersecting shapes).

Why does a good interface for new technologies still lack? Why does type have so many limitations, when “everything is possible”? Questions, questions. [Among many other delights, Underware presents for the first time the remarkable Higher Order Interpolation method.]

  Case study: Higher Order Interpolation for Variable Fonts

14 April 2018
Underware — Underware
HOI could already be very welcome for creating animated fonts in a much more advanced way … “bending” outlines around a curve instead of crudely just shifting the points of the outlines. This would not only reduce the amount of required masters on a time axis, but also lead to much more fluent transitions. Those crude stop-motion animations can now play smoothly in slow-motion for example. HOI could also change or influence the type design process. Until today type designers have always been drawing outlines of static fonts while designing type families. But while designing variable fonts the designer isn’t drawing outlines any longer. Instead, the interpolation curves are actually being designed, the outlines of a static font are just a result from this. This requires a different mindset and approach to the type design process … type designers can start designing correlations between letters, instead of designing the outlines of letters

[26:31] The Type Design and Typography studio at the UMPRUM Academy in Prague will present the results of the semestral research of variable fonts, which took place in the 2017 Winter semester. The research had several aims. The primary aim was to become acquainted with innovation in detail, and to verify how far the proclaimed variability can reach. The secondary aim was to find out how students would utilise technical possibilities to realise their ideas of shape mutations of typeface families. What would be however mostly interesting was whether students could impart an easily recognisable and utilisable character and “content” to such works. Twelve new typefaces will presented by studio tutor Radek Sidun, together with curators Šimon Matějka and Matej Vojtuš.

  Beyond the bubble: Talking to web designers about variable fonts

Laurence Penney — TYPO Labs
[42:29] Here in the font world we’re all fired up about variable fonts, yet we haven’t done much talking about them to typography’s new vanguard: CSS and JavaScript front-end developers. Laurence will share how he explains variable fonts to CSS-focussed audiences. Starting with the familiar (to us) wins in efficiency, tweakability and responsiveness (thx, DJR), he’ll go on to discuss efficient deployment techniques with fallback to static fonts. He’ll also call for a two-way dialogue, because we in the font world need to learn from web experts. We need their help not only with UI for variable fonts, but also for variable font commissions conceptually outside our traditional typographic backgrounds. Animated emoji are only the start!

  Variable Fonts and the Future of Typography

12 April 2018
Jason Pamental — TYPO Labs
[45:33] For centuries, typography has shaped the way we ‘hear’ what we read. In our web work, though, we’ve had to balance our typographic desires with user experience and performance, knowing that every weight, width, or style of a typeface required a different file download. Variable fonts change that. Now, beautiful web typography can be crafted to respond to screen size, language setting, even ambient light. More than just a better version of what we had before, this new technology will challenge our notion of just what is good typography, and how it can push the practice forward in ways never before possible.

While this talk focuses on the Arabic script, the methods can also be extended to other connecting writing systems, as well as Latin script styles.

  Constrained. Unconstrained. Variable

12 April 2018
John Hudson — TYPO Labs
[42:43] The history of typography is the history of the adaptation of design to technological circumstances. When those circumstances are changing rapidly, a single typeface design may need to adapt in several new ways within a short period of time. Coming after a long period of effective technological stasis, variable font technology presents a challenge to designs that were not created with such circumstances in mind, or that were made for different circumstances with their own challenges. John Hudson presents three iterations of a single, complex script typeface adapted to three different circumstances, considering both specific details of the design and general points about process and tools.

  Giving form to Variable Fonts

12 April 2018
Gerry Leonidas — TYPO Labs
[28:50] Or, rather, giving form to peoples’ ideas about Variable Fonts. As for many technological innovations in typography before, the prize lies in the intersection of business and perception: meeting actual needs, while explaining to people how a new technology can be adopted, how it can improve their work, and reduce risk. At the same time, a new generation of professionals need to be trained to use the technology, and extend its utility. This talk is a mini reality check on how we verbalise and visualise Variable Fonts. Those who are not professional typeface designers, yet, are of particular interest.

  Multidimensional Axis Visualizer

10 April 2018
Andrey Kuzmin, Luc(as) de Groot — authors
Avisualizer for any variable font (just drag & drop). Works by creating an n-dimensional cube, where n is the number of axes in the font. Each axis is given a sepaarate colour. The cube can be manipulated directly by the pointer, or you can use axis sliders. Cubes of up to 14 dimensions have been tested. Source on GitHub

  Protipo and the Variable Font Format

19 March 2018
Irene Vlachou — Type-Together
Halfway through the [Protipo] project we realised that these criteria [flexibility, precision, and fine-tuning … a wide variety of weights and styles] match perfectly with the new idea of OpenType font variations, and it would be a real benefit for the user to be able to manually adjust the font to their exact needs. … FeatureVariations allow character switching for typographic tweaks in specific regions of the design space. We call them “jumps” … Protipo Variable uses this technique for ten characters switching in three different values (at weight 400 $¢, at 440 €¥Q and at 600 Øøð), values appropriately tuned for each character.

  How to Use Variable Fonts on the Web

8 January 2018
Anna Monus — Envato Web Design Tutorials
Variable fonts significantly reduce the limitations of current font formats. Today’s web fonts are inflexible and don’t scale very well; they only provide us with some fixed styles with names like “Light”, “Bold”, or “Extra Bold”. There are even typefaces that only have one weight or slant variant. With variable fonts however, we have access to an infinite flexibility of weight, slant, x-height, slabs, rounding, and other typographical attributes.


  Silly hover effects and the future of web typography

Roel Nieskens — Pixel Ambacht
With support for variable fonts inching closer, let’s take a look at what variable fonts are and what they can do. And what better way to demo cutting edge typographic web technology than through silly hover effects? … But if you go beyond those two weights, if you allow this to unlock typographic possibilities previously limited by crude technological constraints, then variable fonts are a dream come true. Browser support is coming real soon, and it brings the future of web typography.

  Variable Fonts: The Second Coming of Gutenberg?

6 December 2017
Allan Haley — Communication Arts
Variable fonts are a hot topic. This new variety of fonts is being heralded by typophiles as virtually the second coming of movable type … enthusiasm—on the edge of ebullience—rules the day … Variable fonts will be important and will change how some of us work, but they are far from the contributions of Johannes Gutenberg, Ottmar Mergenthaler, and even [the Bentons]. The primary benefit of variable fonts is maximizing bandwidth and load time in websites … What should you do? For now, watch and wait.

[1:03:02] The new OpenType variable font format will redefine what it means to make and use a typeface family; in this new format, a single font file can contain multiple weights, widths, optical sizes, and more! I will discuss the development of type families in the 20th and 21st centuries, and share my own experience creating large series of type. I will illustrate why variable fonts have the potential to influence this creative process, and in doing so how they may affect the relationship between type maker and type user.

  An Overview of Variable Fonts in OpenType 1.8

17 October 2017
Peter Constable — Internationalization and Unicode Conferences
The recent introduction of OpenType 1.8 makes it possible to create a single font that can show very different appearances based on user choices. One font has multiple “axes” allowing a fluid, continuous mutation of glyph shapes. This makes it possible for one font to have multiple weights and stresses, in a compact representation that can save considerable space compared to separate fonts. But OpenType 1.8 allows more than just this mutation, which has been around for 30 years already in the form of Apple’s AAT Variations or Adobe’s Multiple Masters. Using OpenType 1.8, it is possible, for instance, to make a font with a “Time” axis, where you can show how the shapes of glyphs have changed over time. Choosing alternates via GSUB substitutions can be given a user interface via this mechanism. This talk will go over OpenType 1.8 and all its capabilities, with live demos showing off some fonts of interest.

  How New Font Technologies Will Improve The Web

18 September 2017
François Poizat — Smashing Magazine
There’s no question, the future of web typography looks promising … Unfortunately, variable fonts don’t solve every problem with responsive web typography. For example, how do we reduce the number of media queries? How do we handle outliers? How do we make the typeface a part of the web page? Parametric fonts are intended to fix these issues … Prototypo … The question now is, What would you do if you could morph typefaces to your every whim?

  User Interfaces in Type Design, opportunities in Variable Fonts

14 September 2017
Santiago Orozco — ATypI Montréal
[25:17] Type design has always had a relationship with technology, and now with variable fonts there are lots of opportunities in that relationship to make type design more exciting than ever. Variable fonts are not only about designing letterforms and making them look good, but about creating systems that offer, to all kinds of users, their own level of interactivity defined by the type designer, manipulated by designers, and consumed by the users. But what will these systems look like, for each of these groups of people? This presentation will look at what is possible with all interfaces for designing, manipulating, and consuming variable fonts.

  Axes, tuples and deltas—oh my!

  User Interfaces for Variable Fonts

25 August 2017
Andrew Johnson — A List Apart
Variable fonts give us a new, wide open typographic space with which to work. Instead of prescribing value to individual UI elements in a vacuum, we should take a hybrid and calculated approach to variable font interfaces. How do we structure our design tools to adapt to the new advantages variable fonts provide us with? … Interfaces for variable fonts should adapt along with the fonts themselves. There’s no single static UI pattern that will work as the best solution for all variable fonts.

  OpenType Font Variations

2 August 2017
David Berlow — Type Network
We’re excited to present the second installment of our publications related to variable fonts. The first installment, which told the stories of Amstelvar and Decovar, showed us beginning to work with variable fonts—imagining, designing, and producing them. Since then, code and browsers have evolved to support the new format, allowing us to start using variable fonts. Naturally, thinking and writing about variations in the context of history and the future can’t be far behind.

  What do Variable Fonts mean for Web Developers?

18 July 2017
Ricardo Magalhães — Medium: Prototypr
Despite Variable Fonts not being quite ready for production use yet, there’s no reason not to keep up with its developments during these early stages. The most optimistic prediction stipulates that they’ll gain massive browser support in mid-2018, so there’s a pretty good chance they’ll explode in usage right from day one, just like CSS Grid did a few months ago. Their possibilities are endless … it’s our responsibility, as designers and developers, to fully understand the extent at which they can (and should) be controlled.

  Variable Fonts: Full Circle 1991–2017

9 June 2017
Thomas Phinney — Kerning 2017
[34:39] In the early 1990s, Adobe and Apple independently developed Multiple Master fonts and GX Variations, competing axis-based font technologies. By 2000, Adobe had abandoned MM, and GX Variations had minimal support in the marketplace. Yet in 2016, an unprecedented alliance of Adobe, Apple, Microsoft and Google announced Variable Fonts (OpenType Variations), a successor to these arguably failed technologies. What makes axis-based fonts so exciting? How do they free type and graphic designers to do new things? Why did they fail before, and why might Variable Fonts succeed when its predecessors failed? FontLab’s Thomas Phinney shows the potential of Variable Fonts from useful workhorses to the silly and bizarre.

  Typographic Potential of Variable Fonts

9 June 2017
Bianca Berning —
As soon as variable fonts are more widely implemented we will see that they can have an impact on our reading experiences that goes beyond faster web loading. I hope this article managed to give an overview of a small selection of opportunities we have at hand to change the way we read on screen. And I’m hopeful that we are one step closer to typography that is not only responsive to how and where the text is read but also to who is reading it.

  Dan Rhatigan on Variable Fonts and the Future of Typography

8 June 2017
Khoi Vinh, Dan Rhatigan — Print Magazine
It’s really the demands of the faster, more powerful digital world around us that’s requiring our fonts to become smaller and that’s requiring a more sophisticated means of delivering typeface designs to people … the likelihood of a variety of new approaches to application UI both excites me and scares me a little … the business outcomes are still anyone’s guess. Every type designer I’ve talked to about this has had a different theory, but since we’re a ways off from widespread support, it will be a while before foundries test the waters and some patterns emerge.

  OpenType variable fonts: How to use fewer fonts and get a lot more typographic richness

11 May 2017
Peter Constable, Shrinath Shanbhag — Microsoft
[31:59] The OpenType font format has been extended with an exciting new technology, OpenType Font Variations. An OpenType variable font is a single font that can behave like many separate fonts by supporting continuous variation between different designs defined in the font. This is the biggest development in OpenType since the introduction of OpenType itself! In this video, we give an overview of OpenType variable fonts, show how some of the capabilities of variable fonts may already be accessible in your existing apps, and describe new DirectWrite APIs that will enable you to take advantage of the full capabilities of this new OpenType format.

  Interpolating the Future

8 April 2017
John Hudson — TYPO Labs
[51:15] Now that variable fonts have (re)introduced interpolable variation into the OpenType format, how else might the technology be used to improve specific aspects of micro-typographic layout? John Hudson presents a series of examples of possible nested glyph variation within font-level variation, some of which are already under consideration as extensions to the existing variable font technology. These examples include improvements to efficiency of CJK glyph storage, complex script shaping, justification, and mathematical typesetting. There are significant challenges to implementing these extensions, but the potential benefits are compelling.

  Axis-Praxis: lessons from 6 months running a website celebrating variable fonts

8 April 2017
Laurence Penney — TYPO Labs
[55:58] In the weeks after the OpenType 1.8 announcement about variable fonts at ATypI 2016, despite explanatory texts and videos there was no environment for enthusiasts and font-makers to experience variable fonts in practice. The following month, Laurence’s Axis-Praxis website fulfilled the need for such a place, somewhere to experiment with your own fonts and to play with fonts that others had released. The site has developed into a resource for fonts, user interfaces, ideas about the future of variable fonts, and reminders of similar activity in font technology a generation ago. Laurence will talk about what he’s learned so far, and will present Axis-Praxis Version 2.

  Creating Variable Fonts from Legacy Families

7 April 2017
Tom Rickner, Bob Taylor — TYPO Labs
[52.49] The dream was to create a tool where you could insert nearly any font family and have a variable font pop out the other end, with virtually no work involved. The reality is not so simple. This talk describes a number of considerations involved in assessing font families for suitability, preparing them for conversion, making the outlines point compatible, and then actually producing high-quality variable fonts that meet the OpenType 1.8.1 standard.

  Make your fonts variable: upgrading existing font projects to OpenType Variations

6 April 2017
Adam Twardoch — TYPO Labs
[48:05] Thousands of font sources exist today which were designed in FontLab Studio, Glyphs or RoboFont with Superpolator, which makes it relatively easy for font foundries to re-release them as variable OpenType fonts. The OpenType Variations model is conceptually and technically quite similar to TrueType GX, MutatorMath and MultipleMaster, but there are some important differences in detail. In this talk, Adam will talk about those differences and will give tips on how to technically approach the conversion of font sources into variable TTFs and OTFs. He’ll discuss differences in the design space setup, caveats about glyph compatibility and feature variation, challenges regarding predefined instances and backwards-compatibility with existing static font families.

23 February 2017
David Sudweeks — FontShop
When reports of new experimentation with the old TrueType GX standard came last year, I was hopeful this might at some point emerge as a new font format, (and I wasn’t alone). What I didn’t suspect was that this variable font technology would become part of OpenType itself. So here’s a quick look at what OpenType is capable of since version 1.8 was announced last fall.

Like an Avengers team of typography heroes, Adobe, Apple, Microsoft and Google have joined forces to support a new standard called OpenType 1.8. So what’s the big deal? … Now we can condense or extend glyphs (specific shapes of letters), customizing them for a specific look. We can sharpen or round a typeface, shorten the descenders, or raise a font’s x-height in our never-ending pursuit of truth, justice and the perfect layout … The biggest companies behind operating systems, design and the Web have all collaborated on the new format. Notable independent contributors are already refining their type standards. It’s a brave new world ahead.

Andrew Johnson announces that the Typeshift app now supports variable fonts. Typeshift is a Mac app for web typesetting, where you can find fonts from various services and develop web layouts.

  Variable Fonts on the Web

2 November 2016
Myles Maxfield — WebKit Blog
The W3C is currently drafting a way to describe variation axis values in CSS … CSS properties …font-weight, font-stretch, font-style, and font-size … optical-sizing … font-variation-settings … TrueType has had variation support for many years. In fact, all of the operating systems Apple ships currently include system APIs for TrueType font variations. Because of this, I have started implementing font variation support in WebKit in relation to the existing TrueType font support in the platform. Currently, I’ve only implemented the lowest-level font-variation-settings property, but I’m very excited to implement the complete support as soon as I’m able. Please try the existing support out in a Safari Technology Preview only on macOS Sierra and let me know how it works for you!

  Caractères versatiles

Baptiste Guesnon —
A wide-ranging discussion of the benefits of dynamic typography: “Aujourd’hui, le texte est mobile, changeant... les contenus et les formes sont en perpétuelle métamorphose. Pourtant la typographie que nous utilisons, bien que numérique, est pensée comme un matériau statique … La typographie dynamique changera la vision que nous avons d’une fonte et de la composition du texte. … l’émergence d’un nouveau souffle dans le champ graphique et typographique.”

  Axis-Praxis: an introduction

Laurence Penney — Axis-Praxis
[5:04] Axis-Praxis is a tool for playing with Variable Fonts in the browser. It’s a simple typesetting environment where you can choose fonts, adjust sliders, and press buttons for Named Instances to obtain precise settings on the variations axes built into the fonts. You can also click the axis buttons for an animation along the entire axis. When you begin you will find, pre-installed in the font menu, the four variable fonts built into macOS Sierra. At any point you can play with your own fonts by just dragging & dropping the TTF file onto the page.

  Variable Fonts in CSS are Crazy Awesome

12 October 2016
Jeff Veen, Tim Brown — Presentable
[46:22] This week’s special guest is my friend Tim Brown, Head of Typography at Adobe. We discuss the recent announcement of Variable Fonts and what that means for type on the web, the complexity of CSS, and the future of responsive web design.

  Variation Fonts Demo

30 September 2016
Myles Maxfield — Litherum
“Try opening this in a recent Safari nightly build.” With these words Safari developer Myles Maxfield introduces the first public demo showing variable fonts working in a web browser. And not just working, but fonts that get new variation settings applied dozens of times per second, thanks to CSS animation. The browser needed is the latest version of WebKit Nightly, a cutting-edge version of Safari for Mac.

  A Great Flowering

Robin Rendle — Adventures in Typography
It began with a post by John Hudson, then Tim Brown wrote about the news over on the Typekit blog, and then Roel Nieskens described the benefits on Typographica. And then, heck, even Wired wrote about the news. But why is this such a big deal?

  Variable Fonts in CSS Draft

22 September 2016
Myles Maxfield — Litherum
Recently, the CSS Working Group in the W3C resolved to pursue adding support for variable fonts within CSS. A draft has been added to the CSS Fonts Level 4 spec. Your questions and comments are extremely appreciated, and will help shape the future of variation fonts support in CSS! … Here is what CSS would look like using the current draft…

  Variable Fonts: the Future of (Web) Type

22 September 2016
Roel Nieskens — Typographica
The introduction of variable fonts is a milestone in digital type history, which was rooted in metal type for a frustratingly long time — at least in the eyes of a computer-nerd type lover like myself. Type has finally adapted to the flexible nature of our screens and the technology that fills them with content.

  Tech Giants Team Up To Fix Typography’s Biggest Problem

22 September 2016
Megan Molteni — Wired Magazine
Engineers at Apple, Google, Microsoft, and Adobe have spent years developing that infrastructure, and the companies expect quick adoption. Google's open source font production pipeline supports variable fonts, and Google hopes to bring it to Chrome and other products ASAP. Adobe expects to release an updated tool for building variable fonts by the end of the month. And Microsoft says it will support variable fonts on all of its products by next year. And designers like Phinney are assembling variable fonts right now, eager for the day when everything, everywhere, is responsive.

Matthew Butterick — Butterick’s Practical Typography
With­out di­min­ish­ing the ef­fort that’s been put into this new stan­dard, I’m not con­vinced there’s a plau­si­ble ra­tio­nale for it. It would im­pose sig­nif­i­cant costs on type de­sign­ers, pro­vide no ob­vi­ous ad­van­tage to our cus­tomers, and mostly ben­e­fit a small set of wealthy cor­po­rate sponsors.

  OpenType Font Variations open up a world of possibilities

19 September 2016
David Berlow — Type Network
I‘m really very happy to see the public display of support for font variations by so many major developers, and such a great public display of interest from so many font developers. Partial full disclosure—the morning after the announcement had been made last week at ATypI 2016 in Warsaw, I woke up with Handel‘s “Variations Chorus” playing in my head, knowing that these announcements had been made while I slept.

  Variable fonts, a new kind of font for flexible design

14 September 2016
Tim Brown — Adobe Typekit Blog
Imagine condensing or extending glyph widths ever so slightly, to accommodate narrow and wide viewports. Imagine raising your favorite font’s x-height just a touch at small sizes. Imagine sharpening or rounding your brand typeface in ways its type designer intended, for the purposes of art direction. Imagine shortening descenders imperceptibly so that headings can be set nice and tight without letters crashing into one another. Imagine this all happening live on the web, as a natural part of responsive design.

David Lemon, Peter Constable, Behdad Esfahbod, Ned Holbrook, Simon Daniels — ATypI
[1:18:58] The announcement of the OpenType 1.8 specification at ATypI 2016 Warsaw, focussing on font variations. Representatives from Adobe, Microsoft, Apple and Google each spoke.

  Introducing OpenType Variable Fonts

14 September 2016
John Hudson — Medium
Version 1.8 of the OpenType font format specification introduces an extensive new technology, affecting almost every area of the format. An OpenType variable font is one in which the equivalent of multiple individual fonts can be compactly packaged within a single font file. This is done by defining variations within the font, which constitute a single- or multi-axis design space within which many font instances can be interpolated. A variable font is a single font file that behaves like multiple fonts.

  OpenType 1.8 specification

14 September 2016
multiple authors — Microsoft
Version 1.8 of the OpenType specification introduces font variations. In the OpenType font file, the fvar table defines axes and named instances. Glyph morphing is defined in the gvar table (in TrueType fonts, with files usually with the extension .ttf), and in the CFF2 table (in fonts with PostScript outlines, files usually with the extension .otf). Various other tables define changes in spacing, kerning, and substitutions that happen in certain regions of the design space.

  OpenType GX: Bringing font variations to OpenType

10 May 2016
Behdad Esfahbod — TYPO Labs
[29:57] Since ATypI 2014, I and a few other people have independently proposed that OpenType should be extended to support runtime font variations à la TrueType GX and Adobe Multiple Master. In this session I will present what has been done in the last year and a half to move towards that vision.

  TrueType Variations: Past, Present & Future

10 May 2016
Tom Rickner — TYPO Labs
[44:45] TrueType Variations was developed at Apple Computer in the early 1990’s, during the height of the “Font Wars”, as a response to Adobe’s Multiple Master font format. This incredibly powerful format briefly flourished as a design tool, before dying in the marketplace for a host of reasons. Renewed interest by designers and software developers alike has resulted in a rebirth of sorts. This talk will discuss lessons learned, current capabilities and limitations of Variations, and will conclude with a vision for what the future of this exciting technology could bring.


  Responsive Lettering

10 November 2015
Erik van Blokland — Letterror
Responsive Lettering is a system for scalable, interpolating vector shapes that can make themselves fit in a range of rectangles. It is intended for publication on the web using SVG for the vector outlines and the snap.js JavaScript library to manipulate them. Source shapes should be in UFO format, so Robofont is typically used to draw them. All code is on GitHub.

  Why OpenType Succeeded Where GX & Multiple Master Didn’t

13 June 2015
Thomas Phinney — ISType
[42:57] There were several attempts to come up with a next-generation digital font format in the 1990s. Why did OpenType (mostly) succeed where GX/AAT and multiple masters did not? Thomas explores the factors that caused GX and MM to fail in the marketplace, and explains why OpenType didn’t suffer the same fate thanks to a combination of accidents of birth, and lessons painfully learned from the previous format battles. Corporate alliances, attention to support and workflows, openness, and tireless evangelism all played their parts.

[41:58] Nick Sherman expands on the many advantages of variable fonts on the web that he described in his A List Apart article.

  Variable Fonts for Responsive Design

23 January 2015
Nick Sherman — A List Apart
The much-cited article that captured the need for a new variable font format for the web: “The lobotomization of dynamic type systems is especially disappointing in the context of CSS—a system that has variable stylization in its DNA. … A variable font would mean less bandwidth, fewer round-trips to the server, faster load times, and decidedly more typographic flexibility. It’s a win across the board.”

  Live Font Interpolation on the Web

20 January 2015
Andrew Johnson — A List Apart
We all want to design great typographic experiences. We also want to serve users on an increasing range of devices and contexts. But today’s webfonts tie our responsive sites and applications to inflexible type that doesn’t scale. As a result, our users get poor reading experiences and longer loading times from additional font weights … With live font interpolation, we can bring the same level of finesse to our sites and applications that type designers do … get involved in the discussion, contribute to projects like opentype.js, and let type designers know there’s a demand for interpolatable fonts.

  The Adobe Originals Silver Anniversary Story: How the Originals endured in an ever-changing industry

30 July 2014
Tamye Riggs — Adobe Typekit Blog
The story of Adobe Multiple Master fonts: what they did well, why they failed. Tamye writes “In 1991, the multiple master format was introduced as an extension to PostScript Type 1. Multiple master fonts, or MM fonts, were built with two or more design masters — outline typeface styles — with font “instances” generated through interpolation along one or more design axes (such as weight, width, and optical size). MM fonts allowed end users greater flexibility and more precise control of their typography than was possible with standard PostScript fonts.”


  Idea: MM webfonts resurrection?

20 June 2013
Adam Twardoch — W3C public-webfonts-wg list
A proposal for a variable font model for the web: “in the web context, I think at least one of [multiple master and TrueType GX] deserves resurrection — because it offers tremendous compression potentials, lends itself well into the “responsive web” paradigm, offers new possibilities for text layout on the web and, above all, can be implemented much more easily on the web than it ever could be on desktop platforms”.


  TypoTechnica 2005 Report: Superpolator

3 March 2005
Ben Kiel — Typographica
Erik van Blokland demonstrated the Superpolator (Super-imposed Interpolation). Simply put, it is an application that allows for a more flexible way of dealing with multiple masters, though it isn’t as interface friendly as FontLab’s way. The power of the Superpolator is that it allows an infinite number of axes and an infinite number of masters. You can have odd numbers of masters (intermediate masters) and even glyph specific masters. You can interpolate multiple times, maintaining as much precision as possible by not rounding point coordinates until the end. … Right now, the Superpolator is a code-base resting on top of RoboFab and requires a bit of programming — about as much as it takes to use RoboFab — to use it.


  Apple’s ‘gvar’ table and friends

23 March 2004
George Williams — freetype-devel list
After a good deal of effort (mostly trying to find someone at Apple who knew anything about it), I believe I finally understand the workings of Apple’s ‘gvar’ table and friends ([acfg]var). Is there any interest in adding support for Apple’s distortable fonts to FreeType? I can provide code to interpret Apple’s tables, but I’d rather have someone who understands the TrueType rasterizer (better than I) undertake the changes to that. Is anyone interested in volunteering?


  Adobe Tech Spec #5091: Designing Multiple Master Typefaces

7 September 1995
Adobe staff — Adobe Systems Inc.
Type 1 multiple master typefaces represent a revolutionary breakthrough in font technology that gives graphic designers and desktop publishers the ability to customize fonts for specific needs. The typographic flexibility that multiple master typefaces provide to users is a significant advantage over previous technologies. To offer users more choices incorporating this flexibility, a variety of multiple master typefaces are currently under development. To encourage further creative application of multiple master technology, Adobe Systems has compiled these basic design guidelines and conventions for creating new typefaces or for “retrofitting” existing families in multiple master format.

  QuickDraw GX Fan Club

1 January 1995
Kenneth Trueman — Kenneth Trueman
QuickDraw GX was the graphics system that Apple introduced in 1994, and variable fonts (or “fonts with GX variations”) were part of that. For about two years up until 1997, Kenneth Trueman operated the QuickDraw GX Fan Club, a website which became a kind of directory of all things GX. That included the fonts, the utilities that made the fonts, and the applications where you could use the fonts. Much of that website is still online.


  Inside QuickDraw GX Fonts

1 October 1994
Erfert Fenton — MacWorld
QuickDraw GX, Apple's long-awaited graphical extension to the Macintosh Operating System, supports an enhanced font architecture that infuses typefaces with a host of new capabilities … quicken the pulse of any digital-type aficionado. … QuickDraw GX fonts can support style variations similar to those of Adobe's Multiple Master fonts. For example, a GX font might allow the user to adjust style axes for width, weight, or optical scaling. Skia, one of the GX fonts included with System 7.5, allows the user to adjust character width and weight.

  Adobe Tech Spec #5015: Type 1 Font Format Supplement

15 May 1994
Adobe staff — Adobe Systems Inc.
This supplement describes … the multiple master font format, which was previously described in Technical Note #5086, “Multiple Master Extensions to the Adobe Type 1 Font Format.” … A multiple master font contains from 2 to 16 master designs in a single font, from which users may interpolate a large number of intermediate font instances. This format, discussed in section 3, provides the potential for unprecedented flexibility and control over typographic parameters.


  Adobe Tech Spec #5086: Adobe Type 1 Font Format, Multiple Master Extensions

14 February 1992
Adobe staff — Adobe Systems Inc.
This technical note presents the format for multiple master Type 1 font programs. The multiple master font format is an extension of the Type 1 font format, which allows the generation of a wide variety of typeface styles from a single font program. This capability allows users and applications unprecedented control over the typographic parameters of fonts used in their documents. A multiple master font program contains two or more outline typefaces called master designs, which describe one or more design axes. The master designs that constitute a design axis represent a dynamic range of one typo- graphic parameter, such as the weight or width. This range of styles is defined in a multiple master font program by specifying one master design to repre- sent each end of an axis, such as a light and extra-bold weight, as well as any intermediate master designs that are required. The maximum number of master designs allowed is sixteen.


  Adobe Moves to Give Users More Typeface Control

11 March 1991
Kristi Coale, Barbara Darrow — InfoWorld
Adobe Systems Inc. has announced a technology that will give designers and end-users more control over typeface appearance. Spanning the Macintosh, Windows, and Unix platforms, Multiple Master technology lets designers and end-users generate several custom variations of a single typeface. Each variation remains faithful to the underlying character shapes, though changing in width, weight, size, and style. The result, according to Adobe, is “aesthetically correct” and does not distort the characters. Due out by year’s end. [Page 1] [Page 2]
