What font does TypeScript use? Segoe UI Web (West European).

TypeScript's website sets its type in Segoe UI Web (West European), on a light #FAF9F8 canvas with #333333 text and a #235A97 accent. Copy the palette and fonts, or a ready prompt to build something original in this style with Claude Code, Cursor, Lovable or v0.

      TypeScript fonts and type scale

      TypeScript's website sets both headings and body text in Segoe UI Web (West European), with Cascadia Mono-SemiLight for code. Body text is 16px, section headings 32px and the largest display type 56px, at weight 400. If you can't use Segoe UI Web (West European), ask your AI for the closest free match and keep the sizes and weights.

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