Type scale

Each size the page sets text in, with its weight and line height. Heroku’s largest type is 40px at weight 600.

Spacing and shape

Spacing sits on a 4px grid: 4px, 8px, 12px, 16px, 20px, 24px, 32px, 40px, 48px, 56px, 60px, 72px.

Corner radii: 2px, 3px, 4px, 5px, 17px, 20px. 2 shadow levels measured.

What makes Heroku look like Heroku

Almost entirely neutral: 97% of the page is painted in #FFFFFF and #F9F9FB.

#300B60 is an accent: 1.5% of the page, used for text only. Don't fill large areas with it.

#0176D3 is an accent: 1.3% of the page, used for backgrounds and text and small fills such as buttons. Don't fill large areas with it.

The largest type (40px Avant Garde) is semibold (600).

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

How this was measured

PikSpec’s scanner read the heroku.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.
