CSS Utility

CSS Clamp Generator

This tool helps you build fluid CSS sizing rules with clamp() so typography and spacing scale more cleanly across viewport sizes.

What it does

• Calculates a ready-to-use clamp() expression from min/max viewport and min/max size values.
• Can export the raw function or a complete CSS declaration.
• Lets you choose the property and unit before copying.
• Reduces manual math when building fluid type or spacing systems.

How to use it

• Open /CSSClampGenerator/.
• Select the target property such as font-size, gap, or padding.
• Enter minimum and maximum viewport widths.
• Set the minimum and maximum value range.
• Copy either the clamp expression or the generated CSS rule.

Use cases

• Fluid heading sizes between mobile and desktop.
• Responsive spacing systems without multiple media queries.
• Design token experiments before moving to a full type scale.
