How many lines on a page? Years ago, before the advent of laser printers with their multiplicity of typefaces, typestyles, and typesizes (i.e., fonts) this was an easy question to answer. The standard vertical spacing for printing was six lines per inch, with eight lines per inch occasionally being used. Thus, an 11-inch-high page would normally contain 66 lines. Most printers were pinfeed printers taking fanfold paper, and would allow you to print right up to the perforation, allowing you to use all 66 lines if you were determined to do so.
