The terms "monospaced" and "fixed-pitch" refer to a typeface whose characters all
have uniform and equal spacing. These typefaces are useful for spreadsheets and
other documents with columnar data. Monospacing is the opposite of proportional
spacing.

The term "proportionally spaced" refers to a typeface in
which the width of each character varies. For example,
the letter "i" is thinner than the letter "m" and therefore
takes up less space. Proportional spacing saves page
space and is easier on the eye. This manual's text
uses the Helvetica font, a proportionally-spaced typeface. Because proportionally
spaced typefaces place each character according to its individual size, they increase
legibility and readability. This example shows the difference between a monospaced
typeface (Courier) and a proportionally spaced typeface (Times).

A bitmapped font is one in which each character is repre-
sented by a set of dot patterns. Each font size requires a
different set of dot patterns.

A scalable font is one in which each
character's dot pattern (bitmap) is
generated from a mathematical rep-
resentation (or outline) of the char-
acter. Scalable fonts eliminate the
need to store different font sizes.

Point size refers to the height of a proportionally spaced type-
face. A point is a unit of measure approximately equal to
1
/
". The larger the point size, the larger the letter. The
72
example shows characters in 8, 10, 12, 24, and 36 point
sizes.
