A slab serif (also called square serif or Egyptian) typeface is a type of serif typeface characterised by thick, block-like serifs. Slab serif typefaces generally have no bracket (feature connecting the strokes to the serifs). Because of their bold appearance, they are most commonly used in large headlines and advertisements but are seldom used in body text. The name "Egyptian" is derived from their use in a publication about treasure from Napoleon's Egyptian campaign. Some consider slab serifs to be a subset of modern serif typefaces.
