Bold (type)

Characteristics

Bold faces are created by increasing stroke thickness and, in some designs, by slightly widening counters and spacing. The result is stronger visual presence and higher contrast on the page or screen. Common characteristics include more robust stems, reduced negative space inside letters, and occasionally subtle changes to proportions to preserve legibility.

History and development

Bold styles emerged as printing and advertising demanded stronger, attention-grabbing text. Early printers and woodcut designers used heavier lettering for headlines and posters. With the rise of metal type and later digital fonts, bold became a standard weight in type families, produced by type designers rather than by mechanically darkening a regular face.

Uses and examples

Typical uses for bold type include headings, subheads, labels, buttons, and emphasis on key words in a body of text. In digital design, authors can apply a bold weight with style rules (for example, using the CSS keyword font-weight: bold) or with semantic markup such as the element to indicate importance. Overuse of bold reduces its effectiveness; it is most powerful when reserved for a few items.
