WEB112 » Legibility vs. Readability
When most people look at a printed or online page, they don’t see the typeface(s) on the page. Instead, they see words and are trying to read them.
Reading is all about the rhythm of the typeface(s) and how they work(s) with the page. The choice of typeface(s) and/or how they are used can either assist or hinder legibility and/or readability of those words on the page.
Readability: refers to the facility and comfort with which text can be comprehended. We don’t read by recognizing one letter at a time, we read by recognizing the whole word at a time.
Legibility: refers to a reader’s ability to easily recognize letter forms and the word forms built from them.
