Source Serif 4 introduces optical sizes, which opens up a wide range of typographic possibilities. Departing from the limitations of outlines designed for a single size, this update makes Source Serif 4 a truly versatile design.

The Caption- and Small Text styles have wide proportions, generous spacing, and light traps to facilitate reading minuscule text. Subhead- and Display styles feature condensed, tightly-set letters, which make for an elegant appearance in headlines. Source Serif 4 is both extension to and replacement of Source Serif Pro — which is comprised in the text size of this family.
