What is a Clamp Generator?

This tool creates CSS clamp() expressions for fluid typography.

It helps you scale text smoothly between viewport widths without many media queries.

How to use

  1. Choose minimum and maximum font sizes in pixels.
  2. Set the minimum and maximum viewport widths where scaling should occur.
  3. Review the generated clamp() expression in the output box.
  4. Resize your browser to check how text behaves responsively.
  5. Copy and paste the CSS value into your styles.

Example usage

Use clamp() for section titles so they stay readable on mobile and feel proportional on desktop.

Tips

  • Use realistic viewport bounds based on your layout breakpoints.
  • Keep min and max sizes close enough to avoid dramatic jumps.
  • Store reusable clamp values in CSS variables.
  • Pair fluid headings with stable body text for balance.
