What font does Linear use?
Linear’s site is a reference point for modern product design, and its typography is a lesson in restraint: one open source family, tuned carefully with variable weights and OpenType features.
Short answer: Linear uses Inter, as a variable font, for nearly all text, with Berkeley Mono for small technical labels. Both are served from Linear’s own static domain.

font-family: "Inter Variable", "SF Pro Display", -apple-system, BlinkMacSystemFont, "Segoe UI", Roboto, Oxygen, Ubuntu, Cantarell, "Open Sans", "Helvetica Neue", sans-serif;- The weights 510 and 590 are only possible with a variable font. They sit just above Medium (500) and just below Semi Bold (600), finer steps than static font files allow.

}How we checked
We opened linear.app in Chrome on September 20, 2026 and read the computed styles of its visible text: the declared font stack, the font actually rendered, and how much of the page’s text each family sets. That is the same data the Font Inspector extension shows under Fonts on this page. We re-check these pages periodically, and the date above shows the last inspection.
