Typography

Bahnschrift is the voice of VDI — condensed, engineered, confident. Fira Sans (brand-supplied, self-hosted, OFL) carries editorial weight for body and long-form.

Usage rules

Do

  • Use Bahnschrift SemiBold or Bold for most headings
  • Reserve the outlined Fira Heavy treatment for posters and key-visuals
  • Use tight negative tracking on display sizes (≥48px)
  • Pair Deep Navy headings with Fira Sans body for maximum contrast

Don't

  • Don't stretch or condense Bahnschrift — use the weight, not the transform
  • Avoid italics in Bahnschrift; italics belong to Fira Sans only
  • Don't set body copy in Bahnschrift at small sizes — it gets brittle under 16px
  • Never pair Electric Green type with blue backgrounds
