What is pitch on an electric typewriter?

On an electric typewriter, pitch refers to the number of characters that can fit within a linear inch of the typeface. It is typically measured in terms of characters per inch (CPI), with common pitches being 10, 12, or 15 CPI. A higher pitch means more characters are packed into the same space, resulting in smaller text, while a lower pitch produces larger text with fewer characters per inch. Adjusting the pitch allows users to control the density and readability of typed documents.
