Key Differences
Legibility focuses on the appearance and distinction of individual characters, making it crucial in design choices for fonts and signage. Whereas, readability is more concerned with the overall ease of reading and comprehending text, influenced by factors like sentence structure and paragraph layout.
Legibility is often evaluated based on the font type, size, and spacing, which affect how easily characters can be distinguished from one another. On the other hand, readability involves the text's organization, language complexity, and the cohesion of ideas within the document.
Poor legibility can hinder the readability of a text, as hard-to-decipher characters slow down the reading process. Conversely, a text can be legible but still hard to read if it lacks proper structuring and concise language.
Designers must balance both legibility and readability to enhance the user experience, considering how each aspect contributes to effective communication.
