Frequently Asked Questions
The best scale is "Fluid," using CSS clamp to smoothly transition between mobile and desktop viewports while maintaining a consistent mathematical ratio like Major Third (1.25).
Divide your target pixel size by your root font size (usually 16). For example, 24px / 16px = 1.5rem. Our tool automates this with 100% precision.
A modular scale is a set of font sizes that are related by a shared ratio. It ensures that every heading and body font on your site "feels" part of the same family.
Yes, our tool is 100% secure. All calculations happen locally in your browser. We never see or store your private design tokens or client projects.
WCAG 2.2 requires that text can be zoomed to 200% without breaking the layout. Using REM units and fluid typography (clamp) is the best way to achieve this.
Clamp takes three values: a minimum, a preferred (using VW units), and a maximum. Our tool generates this complex formula for you instantly.
For body text, a line-height of 1.5 or 1.6 is ideal. For headings, a tighter 1.2 or 1.3 is often preferred. Our tool validates these ratios for you.
Our tool is client-side and requires virtually no data after the initial load, making it perfect for designers on mobile-hotspots or remote sites.
