Pitch and point size
The size of a font is specified as either a pitch or point size, depending on whether the
font is fixed space or proportional.
font is fixed space or proportional.
In
fixed space fonts, each character has the same width. Pitch is used to specify the size
of fixed space fonts. It is a measure of the number of characters that will print in one hori-
zontal inch of type. For example, all 10-pitch fonts print 10 characters per inch (cpi) and all
12-pitch fonts print 12 cpi.
zontal inch of type. For example, all 10-pitch fonts print 10 characters per inch (cpi) and all
12-pitch fonts print 12 cpi.

proportional (or typographic) fonts, every character can have a different width. Since
proportional fonts have characters with different widths, the font size is specified in point
size, not pitch.

Point size refers to the height of the characters in the font. A point is
defined as 1/72 inch. The characters in a font printed at 24 point are twice as large as the
characters in the same font printed at 12 point. The following illustration shows samples of
a font printed in different point sizes:
