The Ubuntu Font Family are a set of matching libre/open fonts. The fonts were originally developed in 2010–2011, further expanded and improved in 2015, and expanded again in 2022–2023 when variable fonts were added.
The development is being funded by Canonical Ltd on behalf the wider Free Software community and the Ubuntu project. The technical font design work and implementation has been undertaken by Dalton Maag, Type Network, DJR, and Dual Type.
Both the final font TrueType/OpenType files and the design files used to produce the font family are distributed under an open licence and you are expressly encouraged to experiment, modify, share and improve.
A monospaced/fixed-width variant, Ubuntu Sans Mono, is available in a separate repository: https://github.com/canonical/Ubuntu-Sans-Mono-fonts
You can find recent releases and release candidates in the "Releases" tab.
Fonts are built automatically by GitHub Actions - take a look in the "Actions" tab for the latest build.
If you want to build fonts manually on your own computer:
make buildwill produce font files.make devwill produce only variable font files.make testwill run FontBakery's quality assurance tests.make proofwill generate HTML proof files.
The proof files and QA tests are also available automatically via GitHub Actions - look at https://canonical.github.io/Ubuntu-Sans-fonts.
It is possible to generate custom styles directly from the variable fonts using fontTools instancer.. For example, the following generates a custom style that is a close match to Ubuntu’s original weight:
fonttools varLib.instancer UbuntuSans[wdth,wght].ttf wdth=100 wght=473
