What is Fluid Typography?

Fluid Typography scales font sizes smoothly based on viewport width using CSS clamp() and viewport units (vw). Text grows/shrinks continuously rather than jumping at breakpoints. Formula: clamp(min, preferred, max) ensures readability across all screen sizes.

When Should You Use This?

Use fluid typography for modern responsive sites, especially content-heavy designs where smooth scaling improves reading experience. Works well for headings that need dramatic size differences between mobile and desktop.

Common Mistakes to Avoid

• •Too much scaling—body text shouldn't scale dramatically; use fluid typography mainly for headings
• •Poor min/max values—ensure minimum stays readable (16px+) and maximum doesn't become comically large
• •Forgetting accessibility—users should be able to zoom; test with browser zoom
• •Complex math—use tools like utopia.fyi to calculate clamp values; manual calculation is error-prone
• •Overuse—not every element needs fluid scaling; use strategically for key typographic elements

Real-World Examples
