How do you structure typography scales for responsive UI design?
To structure typography for responsive UI design, combine modular scales, breakpoints, and fluid sizing techniques:
Use a modular scale (e.g., 1.25 or 1.33) to set proportional font sizes across headings and body text.
Define sizes for each breakpoint (mobile, tablet, desktop) to adjust readability without breaking hierarchy.
Ensure line height and spacing adapt too—not just font size—to keep text readable.
Test on real devices to verify that your visual hierarchy holds across screen sizes.
