Type scale

Each size the page sets text in, with its weight and line height. HubSpot’s largest type is 65px at weight 300.

Spacing and shape

Spacing sits on a 4px grid: 4px, 8px, 12px, 16px, 20px, 24px, 28px, 32px, 40px, 48px, 52px, 56px.

Corner radii: 4px, 6px, 8px, 16px, 42px. 2 shadow levels measured.

What makes HubSpot look like HubSpot

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

#FF4800 is an accent: 0.2% of the page, as small fills such as buttons and badges. Keep it to small areas.

#0000C5 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 (65px HubSpot Serif) is light, not bold (300).

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

How this was measured

PikSpec’s scanner read the hubspot.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.
