Typography is the art of arranging type to make language visible. It involves the selection and use of typefaces and fonts.
A typeface is a set of characters with a common design, such as Verdana. A font is a specific style and size of a typeface, such as Verdana size 9.
There are several categories of typefaces including roman (serif, sans-serif, script, ornamental), blackletter, Gaelic, monospaced, symbol, and display typefaces. Each has distinct characteristics that make them suitable for different uses in design. Typography also involves understanding the anatomy and features of individual letterforms.
