Pitch (typewriter)

Pitch is the number of characters and spaces in one inch of running text, that is characters per inch (abbreviated cpi).[1][2] The pitch is most often used as a measurement of font size of typewriters as well as printers.

The relation between pitch font size and typographic font size is usually inverse: a 12 pitch typewriter font is equal in height to 10 point typographic font, while a 10 pitch typewriter font is equal in height to 12 point typographic font. Though this relation is not obligatory: a smaller in the x-height 12 pitch font can have the body height equal to a 10 pitch font, thus creating a text with increased line spacing.[3]

The most widespread fonts in typewriters are 10 and 12 pitch, called Pica and Elite respectively.[1][2][3] There may be other font styles with various width: condensed or compressed (17–20 cpi), italic or bold (10 pitch), enlarged (5–8 cpi) and so on.
