Open Sans is a sans-serif typeface designed by Steve Matteson and commissioned by Google. According to Google, it was developed with an "upright stress, open forms and a neutral, yet friendly appearance" and is "optimized for legibility across print, web, and mobile interfaces."[3] Featuring wide apertures on many letters and a large x-height (tall lower-case letters), the typeface is highly legible on screen and at small sizes. It belongs to the humanist genre of sans-serif typefaces, with a true italic.

Open Sans is used in some of Google's web pages as well as its print and web advertisements. Its design is almost identical[citation needed] to that of Matteson's Droid Sans, created as the first user interface font for Android phones, but with wider characters and the inclusion of italic variants.


Open Sans is available in a large number of variants. There are five weights (300 Light, 400 Normal, Semi-Bold 600, Bold 700 and Extra Bold 800), each of them with an italic version, totaling ten variants. There is also a separate font called Open Sans Condensed with 3 width variations.[4]

The family also features a number of stylistic alternates, such as a seriffed capital 'I' (for situations where this could be confused with a number '1' or lower-case 'l') and a selectable choice between a single and double-story 'g'. Numbers can be set as tabular, proportional or text figures.


Open Sans is popular in flat design-style web design.[5]

It is used as Mozilla's default typeface for websites and in Telegram Desktop app.[6]

It is the official font of the UK Labour Party.
