n.

1. The letter m.
2. Printing.
   1. The width of a square or nearly square piece of type, used as a unit of measure for matter set in that size of type.
   2. Such a measure for 12-point type; a pica.

Unit of measure of print type equal to the square of a type character. Most machine-set type characters are one-half an em (called an en). The term em is derived from traditional type sets that had a letter M cast on a square slug. The actual size of an em varies, depending on the point size of the type being used. In most cases, the term refers to a pica or 12-point em. Each point equals 0.0138 inch (approximately 1/72 of an inch).

Em-sized spaces are used to indent lines and to make line lengths equal in typeset copy. See also letterspacing.
