Where craft meets code

Good pairings feel inevitable. Great ones set the tone before a single word is read.

Typography sets the tone before a single word is read. A strong pairing creates clear hierarchy while feeling like one consistent voice across every page. This paragraph is set in Karla, while the headline uses Rubik. Numbers like 0123456789, punctuation “quotes” — and ampersands & — reveal a lot about how two typefaces get along.

Contrast, then harmony

Look for contrast in structure and harmony in proportion: similar x-heights, compatible widths and a shared sense of rhythm. Bold text and italic text should feel natural, too.

Why this pairing works

Two sans serifs can work when they differ in structure: Rubik carries the headings, Karla handles text, and hierarchy comes from weight and size. Karla ships in 7 weights, so you can build captions, buttons and emphasis without adding another family.
