Editing X-height (section)

==Other important dimensions==

Lowercase letters whose height is greater than the x-height either have [[descender]]s which extend below the [[baseline (typography)|baseline]], such as ''y'', ''g'', ''q'', and ''p'', or have [[Ascender (typography)|ascenders]] which extend above the x-height, such as ''l'', ''k'', ''b'', and ''d''. The ratio of the x-height to the [[body height (typography)|body height]] is one of the major characteristics that defines the appearance of a typeface. The height of the capital letters is referred to as [[cap height]]. x-height is most important in regular designs, such as most serif and sans-serif designs; [[script typeface]]s that mimic irregular handwriting and calligraphy may not have a consistent x-height across all letters.
