CSS Clamp Generator & Playground

CSS Clamp Generator & Playground

Fluid type should feel like magic, not maths homework.

2 followers

This little lab gadget takes the mystery out of clamp() and turns it into something you can actually use without opening a spreadsheet. Set your min/max viewport widths, dial in the smallest and largest sizes you want, and it builds a perfectly smooth fluid value that scales exactly how you expect. You get a live preview, clean copy-and-paste CSS, and optional presets for headings, body text, and spacing. Plus, guidance on how your fluid value is worked out - missing from most tools.

I built this because I kept finding myself doing the exact same thing every time I started a new layout or theme: opening a calculator, googling “clamp generator”, getting lost in five different formulas, then eventually just guessing a fluid scale that felt right. It was ridiculous for something that should be simple. CSS clamp() is incredibly powerful, but the maths is awkward and most generators either overcomplicate it or hide what’s actually happening. I wanted something small, transparent, and fast — something I could drop into my own workflow and stick onto my website without a build step or a big UI framework. So I made this little tool for myself first. A clean input → clean output flow. A live preview so you see the scaling. Presets for body text, headings, and spacing. And a tiny explainer that actually teaches what clamp() does. It grew into a tiny Labs project that I now use across my WordPress builds, Shopify work, and general design tinkering. If it helps even a couple of other designers or devs avoid spreadsheet-induced headaches, that's a win!
