What Is x-Height?

The x-height refers to the distance between the baseline (the line on which most letters sit) and the mean line of lowercase letters in a typeface. Essentially, it's the height of the lowercase "x" in a particular font, which is why it's called the x-height. This measurement also generally applies to other lowercase letters like "v," "w," and "z."
