Editing Shoe size (section)

===Width===
Some systems also include the width of a foot (or the girth of a shoe last), but do so in a variety of ways:
* Measured foot width in millimetres (mm) – this is done with the [[#Mondopoint|Mondopoint]] system.
* Measured width as a letter (or combination of letters), which is taken from a table (indexed to length and width/girth) or just assigned on an ad-hoc basis. Examples are (each starting with the narrowest width):
** AAA, AA, A, B, C, D, E, EE, EEE is the typical North American system and follows the [[brannock device]] standards, per the system B is narrow, C is regular, D is medium, E is wide, EE is extra wide and so on. The unlettered D size is the norm for men and B for women.
** 4A, 3A, 2A, A, B, C, D, E, 2E, 3E, 4E, 5E, 6E (variant North American).
** C, D, E, F, G, H (common UK; "medium" is usually F but varies by manufacturer—makers [[Edward Green Shoes|Edward Green]] and Crockett & Jones, among others, use E instead, but one maker's E is not necessarily the same size as another's).
** N (''narrow''), M (''medium'') or R (''regular''), W (''wide''), XW (extra wide).
** For children's sizes in North America, typical letters used are M or B (medium), W or D (wide), EW or 2E (extra wide).

The width for which these sizes are suitable can vary significantly between manufacturers. The A–E width indicators used by most American, Canadian, and some British shoe manufacturers are typically based on the width of the foot, and common step sizes are {{frac|3|16}} inch (4.8&nbsp;mm).
