About Fira Sans

Fira Sans is a sans serif family designed to match the character of Mozilla's FirefoxOS and to remain legible on a wide range of handsets with differing screen quality and rendering. The specimen shows a tall lowercase, open apertures in a, c, e and s, a slight angle on some stroke endings and sturdy joins that stay clear in the Black weight. The family has nine weights, Thin 100 to Black 900, each with an italic, for 18 styles supplied as static files; it is not a variable font. Each font holds 2,677 glyphs covering Latin, Latin Extended, Cyrillic, Greek and Vietnamese. According to the official notes, Fira comes in three widths, all with italics, plus a monospaced variant. Carrois, a Berlin type foundry, leads the project; the copyright belongs to The Mozilla Foundation and Telefonica S.A.

Where Fira Sans works

Phone and tablet interfaces
Legibility on screens of varying quality was the stated design goal.
Technical documentation
Italics for all nine weights handle emphasis, and the related monospaced variant can set the code.
Multilingual products
One family covers Latin, Cyrillic, Greek and Vietnamese with the same weight range.
Body text on websites
Regular and Medium have open letter shapes that keep paragraphs clear at ordinary text sizes.
Brand systems
Thin to Black plus condensed sister families give a full hierarchy from one design.
