Each font was a matched set of type, one piece (called a "sort") for each glyph, and a typeface consisting of a range of fonts that shared an overall design. In modern usage, with the advent of digital typography, "font" is frequently synonymous with "typeface". Each style is in a separate "font file"—for instance, the typeface "Bulmer" may include the fonts "Bulmer roman", "Bulmer", "Bulmer bold" and "Bulmer extended"—but the term "font" might be applied either to one of these alone or to the whole typeface. In both traditional typesetting and modern usage, the word "font" refers to the delivery mechanism of the typeface design. In traditional typesetting, the font would be made from metal or wood. Today, the font is a digital file.

If the Font contains the character, this Font will return the corresponding width.

If the Font is a composite Font, the DW entry of its DescendantFont is used. If all previously mentioned approaches fail, the width is estimated based on characters that may be present in the Font.
