Typography
Text typefaces
Traditionally, text is composed to create a readable, coherent, and visually satisfying block of type that works invisibly, without the awareness of the reader. Even distribution of typeset material, with a minimum of distractions and anomalies, aims to produce clarity and transparency.

Readability refers to how easy it is to read the text as a whole, as opposed to the individual character recognition described by legibility. Use of margins, word and line spacing, and clear document structure all impact readability. Some fonts or font styles, for instance sans-serif fonts, are considered to have low readability and so are unsuited for large quantities of prose.

However, even a legible typeface can become unreadable through poor setting and placement, just as a less legible typeface can be made more readable through good design.
