The art of saying less

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 Open Sans, while the headline uses Source Code Pro. 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

Source Code Pro's fixed-width letters signal code and precision — great for headings, labels and data — while Open Sans keeps paragraphs readable. Open Sans ships in 6 weights, so you can build captions, buttons and emphasis without adding another family.
