Cal.com DESIGN.md for Claude Code, Cursor and Lovable

A DESIGN.md is the brief an AI coding tool reads before it writes UI. This one carries everything on this page as rules a model follows: the allowed colours and what each is for, the fonts with free stand-ins, the type scale, spacing, corners, and the things Cal.com’s design never does.

Put it in your project root and ask your tool to follow it: “Read DESIGN.md and build [your product] in this design language.” It describes a style, not Cal.com’s product, so use your own name, words and images.

The measured values as CSS custom properties, with free fonts standing in for licensed ones. Use them to learn from or to start a project in a similar style; Cal.com’s name, logo, words and images are theirs.

How this was measured

PikSpec’s scanner read the cal.com home page in Chrome at 1440px wide on 14 October 2026: the computed styles of its elements, the fonts that rendered and how much of the page each colour covers. Websites change; capture the page yourself with PikSpec for today’s values, any page, and exports in five formats.
