About Typography Calculator
A consistent type system starts with a modular scale, and computing one by hand across every heading level is error-prone. ILikePdf Typography Calculator generates a modular scale from a base size and ratio — from the conservative minor third to the dramatic golden ratio — with live previews of each step rendered as headings. Copy the scale as design tokens for your project. Everything is computed locally, making experimentation instant.
