Pitch and point size The size of a font is specified as either a pitch or point size, depending on whether the font is fixed space or proportional. In fixed space fonts, each character has the same width. Pitch is used to specify the size of fixed space fonts. It is a measure of the number of characters that will print in one horizontal inch of type. For example, all 10-pitch fonts print 10 characters per inch (cpi) and all 12-pitch fonts print 12 cpi: Courier Courier-Bold Courier Courier-Bold 10 Pitch 1234567890 10 Pitch 1234567890 12 Pitch 12 Pitch 123456789012 123456789012 1 inch In proportional (or typographic) fonts, every character can have a different width. Since proportional fonts have characters with different widths, the font size is specified in point size, not pitch. Point size refers to the height of the characters in the font. A point is defined as 1/72 inch. The characters in a font printed at 24 point will be twice as large as the characters in the same font printed at 12 point. The following Understanding Fonts 156
