Similar tables exist as well with which one can estimate the number of characters per pica knowing the lower-case alphabet length. The American pica of 0.16604 inches (4.217 mm). The French pica of 12 Didot points (also called cicero) generally is: 12 × 0.376 4.512 mm (0.1776 in). One pica is further divided into 12 points. There have existed copyfitting tables for a number of typefaces, and typefoundries often provided the number of characters per pica for each type in their specimen catalogs. The pica is a typographic unit of measure corresponding to approximately 16 of an inch, or from 168 to 173 of a foot. For example, an 11-point font (like Helvetica) may have 2.4 cpp, thus a 5-inch (30-pica) line of a usual octavo-sized (6×8 in) book page would contain around 72 characters (including spaces). As books are most often printed with proportional fonts, cpp of a given font is usually a fractional number. The font length is measured there by the number of characters per pica ( cpp). The pica is also used in measuring the font capacity and is applied in the process of copyfitting. ![]() Publishing applications such as Adobe InDesign and QuarkXPress represent pica measurements with whole-number picas left of a lower-case p, followed by the points number, for example: 5p6 represents 5 picas and 6 points, or 5 1⁄ 2 picas.Ĭascading Style Sheets (CSS) defined by the World Wide Web Consortium use pc as the abbreviation for pica ( 1⁄ 6 of an inch), and pt for point ( 1⁄ 72 of an inch).
