How many lines on a page equals one vertical inch?

Answer 1

The lines-per-inch (LPI) is determined by the font size and the spacing between lines.

Answer 2

It depends on the line spacing used in the document. For standard single-spaced lines, there are typically around 10 to 12 lines per vertical inch. For double-spaced lines, there are usually around 5 to 6 lines per vertical inch.

Answer 3

This will vary according to the settings you are using. The font size as well as line spacing will cause it to change.
