What is legible?

Legibility refers to the degree of clarity and ease with which a written text can be read and understood. It is an important consideration in typography, design, and communication because it directly affects how quickly and accurately readers can process information. Legibility is determined by factors such as font choice, typeface size, spacing, line length, and contrast between text and background. For instance, a well-designed and properly-spaced sans-serif font is typically more legible than a script or decorative font with ornate flourishes that may impede reading. In short, legibility is critical to effective communication and user experience in various contexts, such as web design, publishing, signage, and advertising.
