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 Source Serif 4, while the headline uses PT Sans. 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

A modern twist on the classic: PT Sans keeps headings crisp and contemporary, while Source Serif 4's serifs guide the eye along longer lines of text. Source Serif 4 ships in 8 weights, so you can build captions, buttons and emphasis without adding another family.
