IconVault's Fluid Typography generator creates responsive font sizes that scale smoothly between breakpoints using the modern CSS clamp() function. Set your minimum and maximum font size and viewport range, and it outputs a ready-to-paste clamp() declaration. It is free and runs fully in your browser.

Fluid type replaces stacks of media queries with a single line that grows text proportionally as the screen widens, keeping headings readable on phones and impactful on desktops. The tool validates your ranges so the generated clamp() is always mathematically sound.
