Text spacing refers to the amount of space between lines of text, known as line height, and the space between individual letters, called letter spacing or tracking. Proper text spacing enhances readability by preventing letters and lines from appearing too cramped or too far apart. In digital design and typography, adjusting text spacing can significantly impact the overall look and feel of a document or webpage. Tools and software often allow users to customize these settings, ensuring that the text is visually appealing and easy to read for various audiences, including those with visual impairments.
