JetBrains design system

What font does JetBrains use?

JetBrains’s website uses Jet Brains Sans for headings and body text. Jet Brains Sans is not on Google Fonts; the closest free match is Figtree.

Type scale

Each size the page sets text in, with its weight and line height. JetBrains’s largest type is 79px at weight 500.

Spacing and shape

Spacing sits on a 4px grid: 8px, 12px, 16px, 20px, 24px, 32px, 48px, 64px, 96px, 104px, 144px, 200px.

Corner radii: 4px, 8px, 16px, 20px, 24px. 4 shadow levels measured.

What makes JetBrains look like JetBrains

Almost entirely neutral: 98% of the page is painted in #19191C and #000000.

#39013E is an accent: 1.4% of the page, as small fills such as buttons and badges. Keep it to small areas.

#F31199 is an accent: 0.2% of the page, used for text only. Don't fill large areas with it.

The largest type (79px JetBrains Sans) is medium weight, not bold (500), tracked to -0.001em.

JetBrains 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 JetBrains’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 JetBrains’s product, so use your own name, words and images.

As CSS variables

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; JetBrains’s name, logo, words and images are theirs.

How this was measured

PikSpec’s scanner read the jetbrains.com home page in Chrome at 1440px wide on 15 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.
