Typography Scale & Pairing: Turn Font Choices Into Tokens

Picking a heading and body font is quick. Deciding how they behave across product UI, marketing pages and docs is where teams get stuck.

I picked two fonts I liked and never set the scale. Headings fought on mobile and body felt tight. I now set a base size, a ratio, and fluid clamps up front so type stays calm from phone to desktop.

The Typography Scale & Pairing Generator turns those choices into rules you can ship. It creates pairing notes, a responsive scale with clamp values, CSS variables, and plain usage guidance for headings, body, labels and hero type.

You describe the brand feel in a few words, set heading and body fonts, base size, ratio and viewport range, then get tokens that move straight into code.

When the scale looks right, put it into the Design Token Starter Generator and capture the roles in the AI Brand Context / DESIGN.md Generator so coding agents keep the system intact.
