Type scale

Each size the page sets text in, with its weight and line height. Twilio’s largest type is 72px at weight 400.

Spacing and shape

Spacing sits on a 4px grid: 4px, 8px, 12px, 16px, 20px, 24px, 32px, 40px, 44px, 48px, 64px, 96px.

Corner radii: 2px, 4px, 5px, 10px, 17.1px, 20px. 5 shadow levels measured.

What makes Twilio look like Twilio

Almost entirely neutral: 98% of the page is painted in #000D25 and #FFFFFF.

#081F47 is an accent: 1.1% of the page, as small fills such as buttons and badges. Keep it to small areas.

#EF223A is an accent: 0.2% of the page, used for text and small fills such as buttons. Don't fill large areas with it.

The largest type (72px Buffalo) is regular weight, not bold (400), tracked to 0.035em.

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

How this was measured

PikSpec’s scanner read the twilio.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.
