Point Point size refers to the vertical height of a typeface (fig. 5.3).
Point is a unit of measure originally used by typesetters to indicate
the height of a piece of metal type. Computer typefaces are harder
to measure since they are not physical objects. However, the
typefaces provided with the printer, licensed from Linotype, are all
sized by true printing standards.
Pitch Pitch refers to the number of characters per horizontal inch
(fig. 5.4). Ten-pitch Courier prints ten characters per inch. Hence,
ten-pitch type is wider than twelve-pitch type since only ten
characters fill a horizontal inch rather than twelve. Another name
for this measurement is cpi, or characters per inch.
