Fig. A.7 Point Size and x-Height
The height of a lowercase letter without an ascender or descender is
referred to as the x-Height. This measurement varies from typeface
to typeface and can cause an optical illusion where the same size
typefaces appear to be different sizes.
Spacing
Character spacing has two forms, monospacing and proportional
spacing (fig. A.8). Monospaced characters have equal spacing
between each letter which is sometimes referred to as fixed spacing.
An excellent example is the resident Courier typeface. Monospacing
has a mechanical, block look and works extremely well for
spreadsheets where multiple columns of numbers need to be aligned.
