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.
