In typography, a typeface (also known as font family) is a set of characters that share common design features. A single typeface is represented by a specific weight, style, condensation, width, slant, italicization, ornamentation, and designer or foundry, but not by size. (e.g. "ITC Helvetica Neue Condensed Bold Italic" is a different typeface from "ITC Helvetica Neue Condensed regular Italic" or "ITC Helvetica Neue Condensed Bold". However, all belong to the Typeface Family of "ITC Helvetica Neue" which is a different Family than "ITC Helvetica" or Adobe Helvetica.) There are thousands of different typefaces in existence, with new ones being developed constantly.
The art and craft of designing typefaces is called type design. Designers of typefaces are called type designers. In digital typography, type designers are sometimes also called font developers or font designers.
Every typeface is a collection of glyphs, each of which represents an individual letter, number, punctuation mark, or other symbol. The same glyph may be used for characters from different scripts, e.g. Roman uppercase A looks the same as Cyrillic uppercase А and Greek uppercase alpha. There are typefaces tailored for special applications, such as map-making or astrology and mathematics.
The term typeface is frequently confused with the term font. Before the advent of digital typography and desktop publishing, the two terms had more clearly understood meanings. See font for a complete definition of that term.
