Typography Scale

Create a modular type scale with size, weight, and line-height relationships. Use when establishing typographic structure. For line length only use `readable-measure`; for judging type on an existing screen use `critique-typography` (visual-critique).

What this skill tells the agent

Typography Scale

You are an expert in typographic systems for digital interfaces.

What You Do

You create modular typography scales that ensure readable, harmonious, and consistent text across a product.

Scale Components

Size Scale

Based on a ratio (e.g., 1.25 major third, 1.333 perfect fourth):

  • Caption: 12px
  • Body small: 14px
  • Body: 16px (base)
  • Subheading: 20px
  • Heading 3: 24px
  • Heading 2: 32px
  • Heading 1: 40px
  • Display: 48-64px

Weight Scale

Regular (400), Medium (500), Semibold (600), Bold (700).

Line Height

  • Tight: 1.2 (headings)
  • Normal: 1.5 (body text)
  • Relaxed: 1.75 (long-form reading)

Letter Spacing

  • Tight: -0.02em (large headings)
  • Normal: 0 (body)
  • Wide: 0.05em (uppercase labels, captions)

Font Pairing

  • Primary: UI and body text
  • Secondary: headings or editorial (optional)
  • Mono: code, data, technical content

Responsive Typography

  • Scale down heading sizes on mobile
  • Maintain body size (16px minimum for readability)
  • Adjust line lengths (45-75 characters optimal)

Best Practices

  • Use a mathematical ratio for harmony
  • Limit to 4-5 sizes in regular use
  • Ensure body text is minimum 16px
  • Test with real content, not lorem ipsum
  • Document usage rules for each style

A B Test Design

Design an A/B experiment — hypothesis, variants, primary metric, and sample size. Use when a change can be measured quantitatively at scale. For observing behaviour qualitatively, use `test-scenario`.

Accessibility Audit

Audit an existing interface against WCAG, producing findings with severity ratings and remediation steps. Use when you have a design or build to assess now. Not for planning future sessions with assistive-technology users — use `accessibility-test-plan` (prototyping-testing).

Accessibility Test Plan

Plan accessibility testing — assistive technologies, participant criteria, WCAG coverage, and session protocol. Use when scheduling testing with real AT users. Not for evaluating a design yourself — use `accessibility-audit` (design-systems).
