Kerning is the process of adjusting the spacing between individual letters in a font to make them look more aesthetically pleasing. It is an important part of typesetting and graphic design, as it can help create a more visually appealing and balanced design. Kerning is especially important when working with large typefaces, as the spacing between letters can become too wide or too narrow. By adjusting the letter spacing, designers can create a more visually appealing and balanced design.
