Other than the width of individual glyphs and characters (the letter M is usually wider than I), there are also various widths for typeface styles that participate in its personality or help make a content set in a specific width to fit specific conditions.

Some common width styles are: Narrow, Condensed, Regular, Extended and Wide. They serve more as a way to identify each style within a typeface family, rather than standards to follow for all scripts, as they can be different from one script to another.
