Source Sans 3

Source Sans 3 is a sans serif typeface from the Google Fonts open-source library, well suited to clean interfaces, body copy, and UI text where legibility at small sizes matters most. It ships here with 2 real font files — SourceSans3-Italic[wght], SourceSans3[wght] — covering every weight and style Google Fonts publishes for this family, so you can pick the exact cut a layout needs without hunting down extra weights elsewhere.

Because it's released under an open-source license, Source Sans 3 can be used in personal and commercial projects alike, embedded in apps and products, and modified if needed — the full license text is included below so you can see exactly what's allowed. No attribution is required, though crediting Paul D. Hunt is always appreciated.

This listing mirrors the font directly from Google Fonts' own public repository, so what you download here is the same file Google itself serves.
