Point Size and x-Height

Point size comes from an old typesetting term for a typeface's
height. This is measured from the top of highest ascender (the
upward stroke on a character) to the lowest descender (the downward
stoke) within a character set (fig. 7.10).

Descender
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.
