What font does Yarn use? PT Sans and SF Pro.

Yarn's website sets its type in PT Sans with the system font (SF Pro on Apple devices) headings, on a light #FFFFFF canvas with #1C1E21 text and a #0969DA accent. Copy the palette and fonts, or a ready prompt to build something original in this style with Claude Code, Cursor, Lovable or v0.

      Yarn fonts and type scale

      Yarn's website sets body text in PT Sans and headings in the system font (SF Pro on Apple devices), with SFMono Regular for code. Body text is 16px, section headings 24px and the largest display type 32px, at weight 700. If you can't use PT Sans, ask your AI for the closest free match and keep the sizes and weights.

      How do I build a site that looks like Yarn 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 Yarn's look, not its name, logo or copy.
