Build a Fluid Type Scale

Generate consistent clamp() steps for a design-system type scale.

Output unit:
CSS value
font-size: clamp(1rem, 1.5023vw + 0.6479rem, 2rem);

Rendered size at different viewports

375px wideAa 16px
908px wideAa 24px
1440px wideAa 32px

💡 clamp(min, preferred, max) scales a value fluidly with the viewport, then locks at the min and max. It replaces stacks of media queries for typography, spacing, and widths with a single line.

Design Systems tips

🎨

Generate a clamp() for each step of your scale (sm, base, lg, xl…) using the same viewport range.

💡

Store the results as CSS custom properties (--text-lg) for reuse across components.

🎯

Keeping one shared min/max viewport across all steps keeps the scale proportional as it grows.
