The most commonly used ruled papers include wide, college, narrow, quadrille, Gregg, and Pitman ruled. Wide, or legal, ruled paper features a larger 11/32" space between horizontal lines on a sheet. Typically, wide ruled paper is preferred by users with larger handwriting, as well as in schools with younger children. Both college, or medium, and narrow ruled paper have a smaller space between lines. College rule paper has a 9/32" space, which allows for more lines on a page, and is often preferred by users with smaller handwriting. Similarly, narrow rule paper has a 1/4" space between lines.

Quadrille ruled paper is used for graphing and drawing. It features both horizontal and vertical lines evenly space across the page, creating a sheet of same-sized squares. Gregg ruled paper has historically been used for shorthand writing. It has 11/32" space between lines and features a single margin line down the middle of the sheet. Pitman ruled paper is also used for shorthand writing, but it has 1/2" space between lines in addition to the single margin line down the middle of the sheet.
