Source Sans 3, designed by Paul D. Hunt for Adobe, is the expanded successor to Source Sans Pro—the first open-source type family from Adobe. It’s a humanist sans-serif designed for clarity, functionality, and consistency in user interfaces, web design, and editorial work. With an extended range of weights, improved italics, and support for variable fonts, Source Sans 3 has become a modern standard for accessible typography.
Why Designers Love It
Designers love Source Sans 3 because it offers the perfect balance of neutrality and warmth. Its open counters, moderate proportions, and subtle humanist influence make it approachable without being overly stylized. As part of Adobe’s Source superfamily, it works seamlessly with Source Serif and Source Code, creating a complete system for branding and digital design. And because it’s free and open-source, it’s a go-to choice for teams that need a professional typeface at scale.
