Kerning refers to the adjustment of space between individual letters in a word. This practice is essential in typography, as it helps improve the overall appearance and readability of text. Proper kerning ensures that letters are evenly spaced, making the text look more polished and professional. When letters are too close together or too far apart, it can create visual confusion or disrupt the flow of reading. Designers often adjust kerning to achieve a balanced look, enhancing the aesthetic quality of printed materials, digital content, and fonts.
