A standard typographic unit of measure equal to exactly 1/72nd of an inch (1/12 pica).
Prior to the advent of postscript the typographic point (Anglo-American) was only roughly 1/72 of an inch. Prior attempts to standardize the typographic point were put forth by Pierre Simon Fournier, Francoise-Ambroise Didot and Morris Fuller Benton which resulted in a split standard between the European Didot point and the Anglo-American point.
