About CSS Clamp Generator
Between the two screen widths the size grows in a straight line; outside them it stays at the minimum or maximum. The same formula works for spacing, padding and gaps, not only text.
Everything is calculated in this browser tab and nothing you enter is sent anywhere. It keeps working offline once the page has loaded.
CSS Clamp Generator: frequently asked questions
How do I make a font size scale with the screen?
Enter the smallest and largest sizes and the screen widths where each applies. The clamp() value grows smoothly between them.
What happens outside those widths?
The size stays at the minimum on narrower screens and the maximum on wider ones.
Can I use it for spacing?
Yes. The same formula works for padding, margins and gaps.
rem or px?
rem is recommended so text still respects the user’s browser font size; set your root size if it is not 16 px.
