Kerning

In typography, kerning is the process of adjusting the space between two specific characters, or letterforms, in a font. It is not to be confused with tracking, by which spacing is adjusted 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.

The related term kern denotes a part of a typed letter that overhangs the edge of the type block.
