Point (typography)
A point is a unit of measure in typography equal to <math>1 / 72.27<math> inch or sometimes approximated as <math>1 / 72<math> inch; on computer displays it should be equal to a point in typography if the correct display resolution is set, and is often the height of one or two pixels if the resolution is set to 72 or 144 dpi respectively.
A point is the standard unit for measuring font size and leading and other minute items on a printed page.
Twelve points make up a pica. A measurement in picas is usually represented by placing a small p after the number of picas. "10 picas" is thus abbreviated 10p. Likewise, points are represented by placing the number of points after a small p, such as 0p5 for "5 points," 6p2 for "6 picas and 2 points," or 1p1 for "13 points" which is converted to a mixed fraction of 1 pica and 1 point.
