In
typography,
kerning (less commonly
mortising) is the process of adjusting the spacing between characters in a
proportional font, usually to achieve a visually pleasing result. Kerning adjusts the space between individual letter forms, while
tracking (letter-spacing) adjusts spacing uniformly over a range of characters. In a well-kerned font, the two-dimensional blank spaces between each pair of characters all have a visually similar area.
