Do’s and don’ts

Rules written from the measurements, so a coding agent stays on style.

  • Use #000000 for the page and lift surfaces in small steps: #242423.
  • Keep text in 2 levels: #FFFFFF, #B3B3B3.
  • Reserve #FF90E8 for primary actions and key highlights.
  • Set headlines in ABC Favorit with tight tracking (-0.006em).
  • Keep spacing on the 8px grid.
  • Use 4px corners on most elements; larger surfaces also use 6px.
  • Add drop shadows for depth; use tonal surfaces.
  • Introduce new font families beyond ABC Favorit and Arial.
  • Use #FF90E8 for large backgrounds or body text.
  • Make interface transitions slower than 0.2s.

FAQ

Questions

What can I build with the Gumroad DESIGN.md?

Any page or component in this style: a landing page, pricing table, dashboard or sign-up form. Your AI coding agent uses the measured colors, ABC Favorit type, spacing, corners and buttons instead of its own defaults.

How do I use it with Claude Code or Cursor?

Download the file and put it in your project’s root folder, then ask your agent to follow DESIGN.md. Step-by-step guides: Claude Code, Cursor, Codex, GitHub Copilot.

Is this Gumroad’s official design system?

No. Sitepeel measured it from gumroad.com’s public page on October 21, 2026. It is an independent analysis, not made or approved by Gumroad.

Can I use Gumroad’s style in my own product?

Use it to learn, prototype and compare. For a real product, make the style your own, and never copy Gumroad’s logo, name, pictures or text.

How accurate are the values?

Each value was measured on the rendered page after it fully loaded, on desktop and mobile: colors where they appear, type with tracking, spacing, corners, shadows and hover states. Sites change, so check the date at the top.
