Fluid Typography Clamp Generator
Generate a responsive CSS clamp() size between two viewport limits.
Online Tool
Fluid type scales with the viewport.
.fluid-type {
font-size: clamp(1rem, calc(0.583rem + 1.852vw), 2.25rem);
}The formula interpolates between the two size limits across the viewport range, then clamps outside it.
Tool Working Principle
The generator linearly interpolates font size between the selected viewport widths and expresses the result as a CSS clamp() with rem limits and a viewport-based middle value. The limits hold below and above the chosen range.
Step-by-Step Usage Tutorial
- 1Set the smallest and largest font size in rem.
- 2Set the viewport widths where those sizes should apply.
- 3Review the fluid preview and copy the generated CSS.
Frequently Asked Questions
Do I need an account to use Fluid Typography Clamp Generator?+
No. Every tool on TypeTempo runs fully in the browser with no account, email, or API key.
Is my input text stored anywhere?+
Tool calculations use the text in your browser, and the app does not send that input to the TypeTempo application server. A preview may still request font files or other assets from an external provider; those requests do not include the text you entered.
Can I use the output commercially?+
You can use generated text and CSS in personal or commercial work. If a result depends on a named typeface or third-party asset, check that family's or asset's licence before using or distributing its files.
Which browsers are supported?+
The tools are designed for modern desktop and mobile browsers. Font rendering and individual CSS or Unicode features can vary, so check the specific result in the browsers and devices you support.
Does clamp() stop the text from growing without limit?+
Yes. The first and third clamp() arguments set the minimum and maximum. Between the viewport points, the middle calc() value scales linearly.
