What is Legibility?

Unlike readability, which is a general measure of how comfortable a typeface is to read, legibility refers to how quickly and easily individual characters can be identified.

While most typefaces sacrifice legibility in order to improve overall reading comfort, MD IO prioritises shape recognition above all else.
