Set min/max font sizes (px) for each level at min/max viewport
The Fluid Type Generator uses CSS clamp() to make font sizes smoothly scale with viewport width, eliminating media query breakpoints. Set min/max viewport widths and corresponding font sizes to auto-calculate fluid typography code.
Fluid Typography core formula: font-size: clamp(min, min + (max - min) * ((100vw - minVp) / (maxVp - minVp)), max). CSS clamp() was supported by all major browsers in 2020 and is the best solution for responsive fonts. Unlike media queries, clamp() provides smooth transitions at any viewport width without breakpoint jumps.
Fluid typography uses CSS clamp() to make font sizes smoothly scale with viewport width. Unlike media query breakpoints, fluid typography maintains optimal readability at any screen size.
clamp(min, preferred, max) returns a value between minimum and maximum. Commonly used for responsive fonts: clamp(1rem, 2.5vw, 2rem).
Min viewport is typically 320px (smallest phone), max viewport is 1200px or 1440px (desktop). Set based on your design breakpoints.
Fluid typography: no breakpoint jumps, cleaner code, works at any size. Media queries: precise control at specific breakpoints. Modern projects should use clamp() with 95%+ browser support.
Use the clamp() value directly in CSS font-size. For example: h1{font-size:clamp(1.5rem, 4vw, 3rem)}. Or copy CSS variables for unified management.
