What font does Facebook use? Optimistic.

Facebook's website sets its type in Optimistic, on a light #FFFFFF canvas with #111112 text and a #0064E0 accent. Copy the palette and fonts, or a ready prompt to build something original in this style with Claude Code, Cursor, Lovable or v0.

      Facebook fonts and type scale

      Facebook's website sets both headings and body text in Optimistic, with ui-monospace for code. Body text is 15px, section headings 24px and the largest display type 120px, at weight 700. If you can't use Optimistic, ask your AI for the closest free match and keep the sizes and weights.

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