Font pairing

IBM Plex Serif + Open Sans

Heading in IBM Plex Serif, body in Open Sans — a Serif/Sans Serif combination.

The art of typography, made pairable.

Open Sans · Subhead

Great typography starts with a great pair. IBM Plex Serif carries authority in the headline while Open Sans keeps body copy comfortable to read. Together they give a design a coherent voice across sizes, weights and contexts — from hero sections to long-form articles.

Why it works

A Serif display face contrasts naturally with a Sans Serif body face — clear hierarchy, no muddled mood. Both are free from Google Fonts under OFL/Apache and safe for commercial use.
