CSS Clamp Generator creates fluid clamp() expressions from minimum and maximum pixel sizes. It is useful for responsive typography and spacing without complex media queries.
Generate responsive clamp() expressions from min and max font sizes. Everything runs locally in this tab.
clamp(16px, 10.182px + 1.818vw, 32px)
Yes. The tool is free and runs directly in your browser with no account required.
No. Processing happens locally in the browser tab. Your input is not sent to a server.
Generating a fluid clamp() value for font-size, padding, or margin that scales smoothly between a minimum and maximum viewport width, without hand-calculating the vw slope.
The Input box is your minimum size in pixels (default 16), Option A is your maximum size in pixels (default 32), and Option B is the viewport width in pixels at which the minimum size applies (default 320).
It's fixed at 1200px — the size grows linearly from your minimum size at the Option B width up to your maximum size at 1200px viewport width, then holds steady beyond that.
Yes — clamp() works the same way for any length-based CSS property, including padding, margin, gap, and width. Just plug in the pixel values you want to scale between.
A single clamp() declaration replaces several breakpoint-specific rules and produces a smoothly interpolated value at every viewport width in between, rather than jumping between fixed sizes.
No — the generated expression always uses px for the min/max bounds and vw for the fluid middle term, which is the standard, broadly supported pattern for fluid typography.
