AI Typography & Hierarchy: A Readability Checklist for Real Layouts
AI typography is readability engineering—headline scale, body measure, line spacing, and contrast. Use this first-pass checklist before stakeholders see your draft.
Updated June 2026. AI typography is not “pick a trendy font.” It is readability engineering: headline scale, body measure, line spacing, and contrast. Use AI to accelerate layout drafts, then apply a tight checklist before you show stakeholders.
Typography is also where AI outputs “look cheap” fastest—not because fonts are wrong, but because relationships are wrong: headlines that shout without structure, body copy that is too wide, and micro-labels that disappear. Fixing those relationships is mostly editorial, not generative luck.
First-pass readability checklist
- Headline dominance: is the primary message unmistakable in 2 seconds?
- Body measure: are line lengths comfortable for the channel?
- Rhythm: does spacing communicate grouping, not decoration?
Extend the checklist with three more checks that catch real-world failures:
- Contrast discipline: are supporting labels still legible at smaller sizes?
- Line height sanity: does dense UI feel tight but readable, not cramped?
- Pairing coherence: if you use two families, is the role split obvious (display vs workhorse)?
Hierarchy is a sequence, not a single headline
Readers scan in beats: headline → supporting line → proof → action. When AI collapses those beats into one noisy block, comprehension drops even if the design “looks designed.” A practical fix is to force explicit roles in the brief: “headline is 6–8 words,” “supporting line explains who it is for,” “proof is one row of logos or one metric.”
When to iterate in-editor versus regenerate
If the hierarchy is close but type feels slightly off, edit in-editor. If the hierarchy is wrong—wrong emphasis, wrong grouping, wrong scan path—regeneration can be cheaper than local surgery, but only if you change the brief’s structural instructions, not adjectives.

FAQ
Can AI fix bad hierarchy?
AI can propose hierarchy; designers still validate it against context, audience, and brand rules.
Should I standardize type scales across AI drafts?
Yes—define a small set of roles (display, title, body, caption) and reuse them so exploration stays comparable.
