Letter spacing, also known as tracking, refers to the amount of space between characters in a word or sentence. Adjusting letter spacing can enhance readability and improve the overall appearance of text. Designers often manipulate letter spacing to create a specific visual effect or to ensure that text fits well within a given space. In typography, proper letter spacing is crucial for conveying the intended message clearly. Too much space can make words difficult to read, while too little can cause letters to appear cramped. Finding the right balance is essential for effective communication in both print and digital media.
