2656: Kerning: The Basics Mar 26, 2022

Kerning is the process of tweaking the spacing and proportion of the individual letters in a proportional font for printing, meaning that the letters are not all uniformly sized and spaced, such as a typewriter font. There are multiple ways to do kerning, including only adjusting the spacing between pairs of letters, or looking at a text more globally to fit things neatly on full lines. As a result, there is over- and under-kerning, where the letter sets will either be too close together or too spaced apart. Before digital typing, the process of kerning on a printing press was arduous, but there are certain letter pairs, like AV most famously, that were usually kerned to not look so far apart. After digital word processors became more common, many fonts would be programed to adjust spacing for many more combinations.
