Things design system

What font does Things use?

Things’s website uses the system interface font for headings and body text. The system interface font is each visitor's own (San Francisco on Apple devices, Segoe UI on Windows), so nothing loads.

Things colour palette

Things’s home page is light (#F2F5F7 background, #303336 text). Its palette: #F2F5F7, #FFFFFF, #FBFCFE, #303336, #44474B, #2C3138.

Type scale

Each size the page sets text in, with its weight and line height. Things’s largest type is 36px at weight 700.

Spacing and shape

Spacing steps the page leans on: 4px, 8px, 12px, 16px, 20px, 24px, 28px, 36px, 40px, 180px, 200px.

Corner radii: 3px, 4.5px, 5px, 5.472px, 6px, 6.4px. 3 shadow levels measured.

What makes Things look like Things

Almost entirely neutral: 99% of the page is painted in #F2F5F7 and #FFFFFF.

#5C9CF5 is an accent: under 0.1% of the page, used for text only. Don't fill large areas with it.

#4F91FB is an accent: under 0.1% of the page, as small fills such as buttons and badges. Keep it to small areas.

The largest type (36px ui-sans-serif) is bold (700).

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

How this was measured

PikSpec’s scanner read the culturedcode.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.
