In typography, kerning 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 letterforms while tracking (letter-spacing) adjusts spacing uniformly over a range of characters.[1] In a well-kerned font, the two-dimensional blank spaces between each pair of characters all have a visually similar area. The term "keming" is sometimes used informally to refer to poor kerning (the letters r and n placed too closely together being easily mistaken for the letter m).[2]
The related term kern denotes a part of a type letter that overhangs the edge of the type block.[3]
