Red Hat is a geometric sans inspired by American sans serifs like Tempo and Highway Gothic. It’s the official font family used in Red Hat Enterprise software and includes a total of 14 styles in 2 optical sizes (Display and Text) with various weights and matching italics.
The fonts were originally commissioned by Paula Scher (Pentagram) and designed by Jeremy Mickel (MCKL) for the Red Hat identity.
The Display styles have low contrast, large x-height, open counters and are tightly spaced, which make them well suitable for headlines.
The Text styles are optimized for smaller/body text and better legibility, so they have a slightly smaller x-height and narrower width, are spaced more generously, and have thinner joins.
