Slab Serif Font also called mechanistic, square serif, antique or Egyptian, typeface is a type of serif typeface characterized by thick, block-like serifs. Serif terminals may be either blunt and angular (Rockwell), or rounded (Courier). Slab serifs were introduced in the early nineteenth century.
Slab serif fonts are typically used for display purposes—headlines, posters, billboards, logos, and other situations where bold type can stand out.
