About CSS Clamp Generator

CSS clamp() lets you define a minimum value, a flexible preferred value, and a maximum value in one expression. It is especially useful for fluid typography and responsive spacing.

This generator calculates a clamp() expression from your minimum and maximum sizes and the viewport range where the value should scale.

How to use this tool

Choose the CSS property you want to generate.
Set the minimum and maximum size.
Set the viewport range where the value should scale.
Copy the clamp() value or the full CSS rule.

Tips

Use clamp() for headings that should scale smoothly between mobile and desktop.
Use padding or gap clamp values to avoid many breakpoint-specific spacing rules.
Keep the minimum viewport smaller than the maximum viewport.

Yes. It is one of the most common ways to create fluid font sizes without many media queries.

Can I use clamp() for spacing?
