Clamp Generator (CSS clamp calculator)
ClampGenerator is a powerful, free CSS clamp() generator tool built for modern developers and designers to create fully responsive typography and fluid layouts — all without writing media queries.
This tool allows you to visually generate and preview responsive clamp() values for:
Font Sizes & Typescales – with custom min/max viewport widths and typescale presets
Font Settings – apply font families and weights for headings, body text, and code
Layout Properties – generate clamp() values for width, height, margin, padding, and gap
Advanced Shorthands – includes support for directional and shorthand properties like margin-inline or padding-block
🔥 Why I built ClampGenerator:
As a frontend-focused builder, I noticed a gap: existing tools like Typescale or font-size calculators didn’t offer full support for CSS clamp() — especially for developers building design systems or real-world production sites.
I wanted a complete visual playground that combines typography control, layout responsiveness, and real-time code output — all from a single interface. So I built ClampGenerator, with a strong focus on real use cases.
