Create Fluid Responsive Typography

Scale font sizes smoothly between mobile and desktop with one line.

No login required
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

πŸ’‘ 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.

Typography tips

πŸ”€

Set a min size for mobile and a max for desktop; text scales fluidly in between, no media queries.

πŸ’‘

For headings, a wide range (e.g. 28px β†’ 56px) feels dramatic; body text wants a gentle 16px β†’ 18px.

🎯

rem output respects user font-size preferences β€” better for accessibility than px.
