⚠️ Notice: As a showcase of variable fonts, this site requires a web browser that supports OpenType font variation technology. It looks like your browser doesn’t, so please consider upgrading to one that does (the latest versions of Chrome work well, even on older operating systems). Otherwise, the font samples below will only appear as static fonts.
Open-source fonts can typically be used, modified, and distributed free of charge under very permissive terms. Note that there are different open-source licenses with different terms of use. As always, check each font’s license for details.

These prototype fonts were built by Ken Lunde and his colleagues at Adobe for developers to test support for “variable font collections” that combine the technologies for both variable fonts and font collections. The fonts simulate the structure (styles, glyphs, character mapping, features, etc) of Source Han (Serif & Sans) and Noto CJK, but only contain a dozen or so functional glyphs, repeated thousands of times. Lunde’s introduction explains how variable font collections can greatly reduce file sizes for type systems with expansive character support, like Pan-CJK fonts for typesetting East Asian scripts.

Handjet started as an exercise with design students to make a typeface for handset printers and their 32-pixel vertical matrix, but grew into a large multi-script design.
In 2019, Google sponsored and extension and open-source release of the typeface. Consultants for the project include Maria Doreuli (Cyrillic), Irene Vlachou (Greek), Borna Izadpanah (Arabic), Khajag Apelian (Armenian), and Meir Sadan (Hebrew).
The font is provided with a warning that “variable fonts are relatively new and Handjet sometimes challenges the limits. You might get unpredictable, yet beautiful and somewhat amusing, rendering errors in Adobe software. It works well in browsers as far as we know.”
