Roles, not families
One display face for headlines. One neutral sans for details. Stop at two. Poster AI Creator prompts should name both: "headline: condensed bold sans, body: geometric sans."
Size ladder
- Headline: Largest element on the canvas
- Subhead: 60–70% of headline size
- Legal / fine print: Still legible on mobile—never below 24px equivalent
Common fixes
Tracking too tight on all-caps headlines? Add "slightly increased letter-spacing." Lines too long? Break into two lines with a hard hierarchy, not smaller type.
