# Fluid font-size generator

Canonical page: https://nepocore.com/tools/css-clamp/

Generate a fluid font-size expression that scales between a minimum and maximum size across your chosen viewport range.

## How to use it

1. Enter a sample value, color, URL or structured input.
2. Choose the required format or options and run the tool.
3. Review the output and copy it into your own workflow.

## Example

Create a heading that grows from 24 pixels at a 360-pixel viewport to 48 pixels at 1440 pixels.

## Limits and checks

The calculation assumes a 16-pixel root font unless you enter another value. Check the resulting text for readability and wrapping.

## Access and processing

Free to use without an account. Interactive processing requires JavaScript in a modern browser. Input is processed in the browser rather than sent to a processing server. Optional browser storage is not a synchronized account.
