Overpass Font Family

Last Updated on July 13, 2026 by Editorial Team

Overpass is an open source font family inspired by Highway Gothic.

Features:

• supports 43 languages
• includes: arrows, mathematical operatos, box drawing, and symbols
• 11.456 glyphs in total
• 20 fonts (8 roman + 8 italics + 4 monospace)
• available as webfonts and desktop fonts

Created by Delve Fonts for Red Hat.

What you notice first in the Overpass wordmark is the rounded terminal on that lowercase “a” and the way the whole set feels wide and confident without tipping into heaviness.

That’s the highway-signage DNA showing through. Overpass takes the geometry of the U.S. Highway Gothic alphabet, the letterforms designed for maximum legibility at speed on interstate signs, and softens it just enough for screens and print.

The result is a grotesque-style sans that reads as technical and civic-minded but never cold. Wide apertures on letters like “e” and “s” keep small text from clogging up, which is exactly why signage alphabets are built that way in the first place.

Because that legibility bias is baked into the letterforms, Overpass performs well anywhere text needs to be scanned quickly rather than savored: dashboards, transit and wayfinding graphics, government or civic-tech sites, data-heavy interfaces, and product UI where labels and buttons need to stay crisp at small sizes.

It also carries a natural affinity for infrastructure, logistics, engineering, and open source software projects, partly because of its Red Hat origins and partly because the wide, no-nonsense letterforms just look at home next to technical diagrams and code.

Working With the Roman, Italic, and Monospace Styles

Having eight roman weights alongside matching italics gives you real range for a full type system built on one family.

Use the lighter weights for body copy and longer-form UI text, then reserve the heavier weights for headlines, callouts, and navigation where you want the wide highway-gothic character to really show.

The monospace set is worth treating as its own tool rather than an afterthought. Drop it into code blocks, tabular data, timestamps, or technical labels where fixed-width alignment matters, and let the roman styles handle everything else.

Because roman, italic, and monospace all share the same underlying structure, they sit together cleanly, so you can mix them within a single layout, say monospace for a stat and roman for its label, without the pairing feeling forced.

When you’re building out a hierarchy, start by setting your base body size in one of the middle weights, then jump at least two weight steps for headings rather than relying on size alone. That keeps the signage-inspired boldness intentional instead of accidental.

The extensive language support and full symbol set, including arrows and mathematical operators, mean you can lean on Overpass for interface icons made from glyphs, directional cues, and multilingual documentation without swapping in a second typeface for edge cases.

Pair it with a humanist serif for editorial contrast, or keep a layout entirely in Overpass and let the weight range alone carry the hierarchy for a cleaner, single-family system.
