The three main categories of typefaces are as follows: Classical, modern and calligraphic. The Association Typographique Internationale or ATypl, an internation non-profit organization which is dedicated to typography, established the Vox-ATypl classification as the standard for categorizing typefaces.
These three main categories can also be divided into further subcategories – Classical typeface which is also referred to as “old style” contains humanist, transitional and garald, modern typeface contains didone, mechanistic and lineal which can either be grotesque, neo-grotesque, geometric and humanistic, and calligraphic typeface contains glyphic, script, graphic, blackletter or bold and gaelic. A lot of people get confused with using typefaces and fonts – some even use the words interchangeably – however, a font is just a member of a typeface such as italic, roman or boldface.
