What font does MUI use? IBM Plex Sans.

MUI's website sets its type in IBM Plex Sans, on a light #FFFFFF canvas with #1A1E23 text and a #0073E6 accent. Copy the palette and fonts, or a ready prompt to build something original in this style with Claude Code, Cursor, Lovable or v0.

      MUI fonts and type scale

      MUI's website sets both headings and body text in IBM Plex Sans. Body text is 16px, section headings 24px and the largest display type 56px, at weight 600. If you can't use IBM Plex Sans, ask your AI for the closest free match and keep the sizes and weights.

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