Source Serif Pro is a serif typeface designed by Frank Grießhammer and released by Adobe in 2014 as part of the Source font family. It was created to complement Source Sans Pro and Source Code Pro, providing a complete type system for editorial and publishing applications.

History and Design

Frank Grießhammer developed Source Serif Pro while working at Adobe. The design draws inspiration from the transitional serifs of Pierre Simon Fournier, blending historical elegance with contemporary functionality. The typeface features a moderate x-height, subtle bracketed serifs, and classical proportions that perform beautifully both in print and on screen.

Why Source Serif Pro is Popular

Source Serif Pro has become a go-to choice for designers seeking a high-quality free serif alternative to premium typefaces like Georgia, Times, and Tiempos. Its comprehensive character set, excellent language support, and professional design make it suitable for newspapers, magazines, books, and digital publications. The Adobe pedigree ensures exceptional quality and ongoing development.

Technical Features

  • Optical sizes: Designed to work well at both text and display sizes
  • Extensive character set: Supports Latin, Cyrillic, Greek, and Vietnamese
  • OpenType features: Small caps, old-style figures, tabular figures, and ligatures

Usage Tips
