Pitch (typewriter) explained

Pitch is the number of (monospaced) letters, numbers and spaces in 11NaN1 of, that is, characters per inch (abbreviated cpi), measured horizontally. The pitch was most often used as a measurement of the size of typewriter fonts as well as those of impact printers used with computers.

The most widespread fonts in typewriters are 10 and 12 pitch, called Pica and Elite, respectively. Both fonts have the same x-height, yielding six lines per vertical inch. 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.

Pica, the typewriter font, should not be confused with pica, a unit equal to of an inch or twelve points, usually measured vertically.
