More than two typefaces

Forbidden
A serif for headings, a script for the description, a sans for the UI
Instead
One sans serif for everything is the safe default: most legible at small sizes, neutral enough to suit any brand, and it keeps the content rather than the lettering as the focus.

What this rule looks like

Forbidden
Instead

Why this rule

A second typeface is permitted for headings only, where the brand needs a mood the sans cannot carry. Never a third. Never a script or display face below heading size — they are drawn for large sizes and become unreadable small.
