Source Serif 4

Primary serif for headlines, page titles, hero statements, pull quotes and high-impact authority statements.

Source Serif 4 should not be used for dense body copy or extended digital reading.
  • Confident, credible, composed, modern – authority with warmth and restraint.
  • Most effective when used large, with space and contrast. Highly legible across sizes – maintains clarity and rhythm from statements and pull quotes to supporting text.
  • Free, open-source, variable font – future-proofed and governance-friendly.
  • Scales across reports, web, decks, legal, investor comms.

Governance-friendly typography means open-source, license-safe fonts that scale across a multi-brand group, reduce legal and operational risk, and remain robust even when used by non-designers.
