      Three.js fonts and type scale

      Three.js's website sets both headings and body text in Roboto Mono, with Roboto Mono for code. Body text is 16px, section headings 28px and the largest display type 48px, at weight 500. If you can't use Roboto Mono, ask your AI for the closest free match and keep the sizes and weights.

      How do I build a site that looks like Three.js with AI?

      Open the Prompt tab above, change its first line to what you are building, and paste it into Lovable, v0, Bolt, Claude Code or Cursor. For a whole project, install the Claude skill or the Cursor rule instead, so every screen keeps the style. Build something original: keep Three.js's look, not its name, logo or copy.
