Roboto Slab & Open Sans font pairing

Pair Roboto Slab for headlines with Open Sans for body copy when you want clear UI hierarchy. Roboto Slab carries display weight and brand voice; Open Sans keeps paragraphs and helper text readable at smaller sizes. Download both from Google Fonts and test at 16–18px body with a bold or medium heading scale.

• Landing heroes: Roboto Slab at large sizes, Open Sans for supporting sentences and CTAs.
• Product UI: keep Open Sans for forms, tables, and settings; reserve Roboto Slab for page titles and empty states.
• Portfolios: use the contrast between Roboto Slab and Open Sans to separate case-study titles from captions.
