Get this font on Google FontsSource Sans 3 is a clean, neutral sans-serif with open letterforms and consistent stroke widths that make it highly legible at a range of sizes. Designed by Paul D. Hunt for Adobe, it carries a professional, no-nonsense character without feeling cold or mechanical. Its slightly humanist touches give it enough warmth to feel approachable, while its overall structure keeps things orderly and efficient. It handles long stretches of text well and remains clear at small sizes, which is part of why it has become a go-to choice for functional design work.
Source Sans 3 works well as a UI font for web applications and dashboards where readability under varied conditions matters more than visual flair. It is a solid choice for documentation, technical writing, and government or institutional websites that need to communicate clearly without distraction. It also holds up well in editorial layouts for digital publications where body text needs to stay comfortable across devices and screen sizes.
