Main parts
- 01Foundation or token
- 02Applied component
- 03Visible state and rule
Use it when
Use it to keep text levels consistent while they adjust at screen breakpoints.
Do not use it when
Never keep a perfect math pattern if it makes real words hard to fit or read.
Name used in code
clamp() type scale Before you ship
Check content order, shared design values, component consistency, contrast, zoom, and layout changes by screen size. Verify every theme, language, and state. If there is motion, offer an equal reduced-motion experience.
Outcome: Use or define Type Scale to make the visual experience clear and easy to use. User context: The product uses four heading sizes and three body sizes. It doesn't invent a size for each screen. Design concept to apply: Type Scale. Why it fits: Use it to keep text levels consistent while they adjust at screen breakpoints. Do not use it when: Never keep a perfect math pattern if it makes real words hard to fit or read. Design requirements: Set the content order, shared design values, and reusable components. Define how the layout changes by screen size and state. Keep useful design choices separate from decoration. Inclusion and resilience: Check contrast, zoom, languages, themes, and reduced motion when needed. Do not use color or effects as the only way to show meaning. Acceptance criteria: The design stays clear on phones and desktops, at zoom, in every theme, and in all supported languages. Interactive states stay clear and consistent. Evidence and limits (evidence boundary): No single official standard controls the whole term. Its meaning may change across teams, platforms, or frameworks. Unknowns to confirm: Brand limits, amount of content, supported themes and languages, target devices, and design-system rules.

Release checks: Check content order, shared design values, component consistency, contrast, zoom, and layout changes by screen size. Verify every theme, language, and state. If there is motion, offer an equal reduced-motion experience. Before changing code, report the evidence you found, gaps, severity, and the smallest safe fix.
