01 What It Does

Build a Coherent Type System

A typography-system reference covering modular sizes, weight, leading, tracking, font roles, and responsive use.

Source-based workflowNot an execution benchmark

The Working Approach

Typography Scale combines size relationships with weight, line height, and letter spacing. It treats a type system as more than a sequence of font sizes: a caption, body paragraph, heading, and display line need different roles and conditions of use.

The source includes example modular ratios and font-role choices, plus mobile guidance for headings and reading measure. These are starting rules to test with actual content. It does not claim that a mathematical ratio alone guarantees readable typography across every font or script.

Expected Deliverables

  • A named text-style scale with size, weight, line height, and tracking.
  • Font-role assignments for body, headings, and technical text.
  • Responsive usage rules and real-content checks.

From Brief to Review

  1. 01
    Choose the Base Relationship

    Select a body baseline and ratio appropriate to the content and existing brand.

  2. 02
    Define Complete Styles

    Pair each size with weight, leading, tracking, and a clear usage role.

  3. 03
    Test Real Text

    Check long headings, body paragraphs, and mobile widths; avoid introducing unnecessary sizes to repair individual cases.

02 When to Use It

When to Use It

Requires the actual font files or available platform fonts for meaningful visual validation.

A Good Fit

  • Inconsistent Text StylesUseful when a product has accumulated near-duplicate headings and labels.
  • New UI FoundationsEstablishes type roles before screens invent their own scales.

Limits to Check

  • Not Only Reading MeasureLine length matters, but this Skill addresses a broader type system.
  • Not a Typeface LicenseFont selection and usage still require appropriate licensing and platform availability.

Bring These Inputs

  • Fonts and BrandProvide approved families, available weights, and existing constraints.
  • Content SamplesInclude realistic labels, headings, paragraphs, code, or numerical displays.
  • Screen ContextsDescribe mobile, dense UI, and long-form reading requirements.

03 Decisions That Matter

Decisions That Matter

  1. Styles Carry Roles

    Documented use cases reduce arbitrary decisions between neighboring sizes.

  2. Mobile Without Shrinking Everything

    The source differentiates scaling headings from preserving a readable body baseline.

Requires the actual font files or available platform fonts for meaningful visual validation.

Start With One Deliverable

Adapt the scope, source material and constraints in this brief before running the skill.

Example Brief
Use typography-scale for a research reading app with article text, notes, navigation labels, and code excerpts. Define a restrained modular scale with complete style values and mobile heading behavior. Test against the supplied long titles and paragraphs rather than placeholder text.

Inspect the Result

Check the actual output against these observable criteria.

  • Every style includes more than a font-size value.
  • Frequent text roles use a limited set of styles.
  • Long headings and body copy remain readable at narrow widths.

06 Questions Before You Start

Questions Before You Start

Does a modular scale choose the font?

No. The ratio organizes sizes; font selection and actual rendering still require judgment.

Should all desktop sizes shrink on mobile?

The source suggests reducing headings while preserving a readable body size and adjusting line length.

How many styles should be used regularly?

The source recommends limiting routine use to a small set, while documenting additional roles such as captions or display text.
