What font does IBM use? IBM Plex Sans.

IBM's website sets its type in IBM Plex Sans, on a light #F4F4F4 canvas with #161616 text and a #0F62FE accent. Copy the palette and fonts, or a ready prompt to build something original in this style with Claude Code, Cursor, Lovable or v0.

      IBM fonts and type scale

      IBM's website sets both headings and body text in IBM Plex Sans, with IBM Plex Mono for code. Body text is 14px, section headings 32px and the largest display type 42px, at weight 300. 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 IBM 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 IBM's look, not its name, logo or copy.
