Cap height typically ranges from 60% to 75% of a typeface's point size; a 16 pt font might have a cap height of around 11 pt. Designers use cap height to align mixed-size text optically and to size icons or small caps that should visually match capital letters. In CSS, the 'cap' unit (supported in modern browsers) directly references this value, enabling precise text-relative sizing.
