Typeface x-
rating
A typeface x-rating refers to the height of the typeface as measured by the
vertical space occupied by the lowercase letter x. This proportion varies for
each typeface making some typefaces easier to read than others in the same
point size.
Figure 5-9 shows how greater x-ratings in the same point size and same
typeface may increase legibility.

changing point size.
