Source Sans 3
Interactive font preview
Source Sans 3 is a sans serif family built for broad editorial and interface use, with a wide weight range from 200 to 900 and matching italic styles. Its variable format adds smooth control across the spectrum, making it easy to tune from airy and restrained to dense and assertive without changing families. With coverage for Latin, Latin Extended, Cyrillic, Cyrillic Extended, Greek, Greek Extended, and Vietnamese, Source Sans 3 is suited to multilingual systems that need a clean, adaptable voice.
Source Sans 3 works well in UI text, data-heavy layouts, documentation, and long-form reading where clarity and consistency matter. Lighter weights can feel open and understated, while heavier weights support hierarchy, labels, and emphasis. Because the family stays functional across many scripts, it pairs best with type that brings contrast in texture or structure, especially when you want the sans serif to remain the steady, readable anchor in the composition.
