How to use CSS Clamp Generator
Derive fluid CSS clamp sizing from two viewport and size anchor points. The preferred linear size interpolates between the anchors. Bounds remain the smaller and larger sizes even when the requested size decreases as the viewport grows.
- Provide the input and select the documented mode or options.
- Run the tool and review its result and any limits reported below.
- Copy the text result or download a separate output file.
Good to know
- Viewports must be distinct positive pixels and sizes nonnegative. The rem output assumes the supplied root font size.
- Viewport width means the CSS vw unit. Container-query units, zoom behavior and a site-specific type scale are not inferred.
- Processing happens in this browser tab. Inputs and results are not automatically saved or uploaded.
