Roboto Slab and Assistant font pairing
Serif headings with a sans serif body.
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 Assistant, while the headline uses Roboto Slab. Numbers like 0123456789, punctuation “quotes” — and ampersands & — reveal a lot about how two typefaces get along.
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.
