Slab serif fonts
Slab-serif families with block-like serifs, from geometric and typewriter-flavored designs to sturdy text faces with italics.
Solid ground
A slab serif has serifs that are as thick, or nearly as thick, as the main strokes, and usually meet them at a right angle. The style appeared in early nineteenth-century advertising, where it was called Egyptian, and it has kept a reputation for sturdiness ever since. Slabs suit headings that should feel confident without shouting, and in their text versions they are some of the most robust faces for small sizes and poor screens.
The category is broader than it first appears, and it helps to know the main branches. Geometric slabs have even strokes and round bowls, like a sans with blocks added. Bracketed slabs, sometimes called Clarendons, soften the join between serif and stem with a curve and show more contrast; they read as warmer and more traditional. Humanist slabs take their proportions from text serifs and are the ones for paragraphs. Typewriter-style slabs are light and monoline.
When choosing, decide first whether you need text, headings or both. For text, look for italics and moderate weight. For headings, the heavier and wider cuts carry more character, and a variable weight axis lets you find the exact color you want.

Questions about slab serif fonts
When should I choose a slab serif over a regular serif?
When you want a firmer, more even texture: for headings, short blocks of text, or small sizes on screens. Their thick serifs survive conditions that break up fine ones.
Do slab serifs work for body text?
The humanist and bracketed kinds do, especially those with italics and moderate weight. Very geometric or very heavy slabs are better kept to headings.
Can I use these slab serifs commercially?
Yes. All are under the SIL Open Font License except Roboto Slab, which uses the Apache License 2.0. Both allow commercial use; the Apache license asks you to keep the license text and notices with the files.
