Slabtype

Slabtype is a term used in typography to describe a typeface classification characterized by its slab-like serifs. These serifs are thick, rectangular, and unbracketed, giving the font a sturdy and robust appearance. Slab serif fonts are also known as Egyptian fonts or Robbed serifs. This style originated in the early 19th century, becoming popular during the Industrial Revolution due to its legibility and impact, often used for advertising and signage.

The defining feature of slabtype is the presence of these heavy, square serifs that are typically the same thickness as the main strokes of the letterforms. Unlike traditional serif fonts where serifs are often thin and bracketed (gradually transitioning from the serif to the stem), slab serifs are abrupt and distinct. This creates a uniform visual weight throughout the letter, contributing to its bold presence.

Slab serif typefaces can be broadly categorized into two main groups: those with a more consistent stroke width throughout the letterform and serifs (often referred to as monolinear slab serifs) and those that retain some variation in stroke width, similar to older serif styles (known as modulated slab serifs). The former often appear more modern and geometric, while the latter can have a more classic or even vintage feel. Slabtype fonts are widely used in various applications, from display headlines and branding to book covers and even body text where a strong, distinctive voice is desired.
