Altura de x

Definición

La altura de x es la altura tipográfica de las letras minúsculas de un tipo de letra, específicamente la altura de una 'x' minúscula plana medida desde la línea base, típicamente expresada como fracción del tamaño em.

Explicación

A high x-height (relative to cap height) makes text appear larger and more legible at small sizes, which is why typefaces designed for screens — such as Georgia and Verdana — have notably tall x-heights. X-height typically ranges from 40% to 75% of the cap height. In CSS, the 'ex' unit is defined as the x-height of the current font, though in practice most browsers approximate it as 0.5 em.
