Side-by-Side Comparison
Shoe Sizes
Adult Shoes vs. Shoe Widths
Comparing 2 standards across 13 specifications. 13 key differences identified.
Comparing:
Adult Shoes
Shoe Widths
Universal adult shoe size conversion matrix comparing foot length in centimeters, millimeters (Mondopoint), and inches against standard sizing systems: US Men's, US Women's, UK (Barleycorn), European (Paris Points), and Japanese (JP cm).
Shoe width classifications standardize forefoot ball joint circumference and sole width relative to shoe length. Measured using the Brannock Device, widths span from 4A/AAAA (Super Slim) to 6E (Maximum Wide), with each letter step representing a 3/16-inch (4.76 mm) increase in ball circumference.
