Quick answers
When should I pick Typography scale?
When the story is: decks, handouts, classroom posters, resume headers.
When should I avoid Typography scale?
Skip it in cases like: random point sizes per slide with no shared ratio.
Who invented or popularised it?
Classical modular scales; modern UI ramps in open font ecosystems
What does it encode?
relative font sizes on a ratio (major third, perfect fourth, etc.)
Is it OK in ads?
Yes if one claim is visible at a glance in Meta, Google and retail print; otherwise link to a full figure.
Will a teacher accept it?
Yes for lab reports and poster boards if axes, units and a source line are present.
Typography scale encodes values as relative font sizes on a ratio (major third, perfect fourth, etc.). Classical modular scales; modern UI ramps in open font ecosystems.
In reports, ads and assignments it fits decks, handouts, classroom posters, resume headers. Skip it when random point sizes per slide with no shared ratio.
Principles
- Encoding — The core mark of Typography scale is relative font sizes on a ratio (major third, perfect fourth, etc.).
- History — Classical modular scales; modern UI ramps in open font ecosystems
- Fit — decks, handouts, classroom posters, resume headers
- Shared baseline — The eye compares length and position more accurately than area.
- Audience — PowerPoint, Excel or Google Sheets and Meta, Google and retail print share the same geometry.
Misconceptions
- Pretty equals true — Decoration rarely persuades; it slows reading.
- 3-D helps — Perspective distortion wrecks comparison. Keep it flat.
- More series is richer — Do not stack stories. One Typography scale, one claim.
- Default palette is fine — Rainbow defaults fail color-blind viewers and grey print. Change Excel or Google Sheets defaults.
Why it matters
- Work — Work: decks, handouts, classroom posters, resume headers. Readable in four minutes in PowerPoint.
- Ads — Ads: one number and one shape speak first in Meta, Google and retail print.
- School — School: for lab reports and poster boards, pick the form that answers the rubric.
- Craft — Craft: honour relative font sizes on a ratio (major third, perfect fourth, etc.) and decoration falls away.
Typography scale: honour relative font sizes on a ratio (major third, perfect fourth, etc.), and switch when random point sizes per slide with no shared ratio.
