The x-height is literally the height of the lower-case x character. =F0=9F= =98=80 But it's used as a shorthand to say something about the characteristics of a font -- the x-height is what matters most for legibility, and the ascenders (in characters like "b") and descenders (in characters like "g") are separate things. Fonts with equal heights but different x-heights mix badly visually. --=20 (domestic pets only, the antidote for overdose, milk.) bloggy blog: http://lars.ingebrigtsen.no
