Similar tables exist as well with which one can estimate the number of characters per pica knowing the lower-case alphabet length. 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. 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). The contemporary computer PostScript pica is exactly 1⁄ 6 of an inch or 1⁄ 72 of a foot, i.e.So the behavior isn't usually considered a disorder unless a child is older than 2.

The French pica of 12 Didot points (also called cicero) generally is: 12 × 0.376 = 4.512 mm (0.1776 in).In printing, three pica measures are used: One pica is further divided into 12 points. The pica is a typographic unit of measure corresponding to approximately 1⁄ 6 of an inch, or from 1⁄ 68 to 1⁄ 73 of a foot. A ruler showing Pica scale (on the top) and Agate scale (on the bottom)
