cpi
Last modified: Tuesday, May 21, 2002
Short for characters per inch, a typographic measurement specifying the number of characters that can fit on a printed line one inch long. The measurement really makes sense only for fixed-pitchfonts where every character has the same width. For proportionally-spaced fonts, the cpi represents an average number rather than an absolute number.
