Source Serif Pro is a serif typeface in the transitional style, designed to complement Source Sans. Their close companionship is achieved by a careful match of letter proportions and typographic color. While designed to harmonize with its serif-less counterpart, Source Serif often takes its own direction, in part because the two are inspired by different historical precedents. Source Serif is loosely based on the work of Pierre Simon Fournier, and many idiosyncrasies typical to Fournier’s designs (like the bottom serif on the b or the middle serif on the w) are also found in Source Serif. Without being a pure historical revival, Source Serif takes cues from the Fournier model and reworks it for a modern age.
Source Sans and Source Serif also have different personalities because they spring from the hands of different designers. Source Serif was designed by Frank Grießhammer, Source Sans was designed by Paul Hunt. Robert Slimbach consulted on both designs, which helped maintain the overall family harmony. Either design feels confident on its own but also works in combination with the other — just like their designers do.
Source Serif continues Adobe’s line of high-quality open source typefaces. Designed for a digital environment, the letter shapes are simplified and highly readable. Its historical roots, combined with the guidance through an experienced designer give the typeface a strong character of its own that will shine when used for extended text on paper or on screen.
There is still more to come for Source Serif. Additional weights, Italic cuts, and Cyrillic and Greek language support are all planned.
