Definition of "Legibility" by Graphic Design Newcastle:
« Back to Glossary Index
Legibility refers to how easily individual characters or letters in text can be distinguished from one another. It is a key aspect of typography and graphic design that affects how quickly and accurately a reader can recognize and read text. Legibility is influenced by factors such as:
- Typeface design (e.g., serif vs. sans-serif)
- Font size
- Letter spacing (tracking)
- Line spacing (leading)
- Contrast between text and background
- Text case (uppercase vs. lowercase)
In essence, legibility ensures that the text is clear and readable at a glance, which is especially important in signage, headlines, and user interfaces.
