Shoe Size - Shoe Size Comparison

Shoe Size Comparison

Please, note that the following tables indicate theoretical sizes calculated from the standards and information given above. Differences between these tables and makers' tables or other tables found on the Web are usually due to the following factors:

• The systems are not fully standardised. Differences between shoes from different makers, which are due to different methods of measuring the shoes, different manufacturing processes, or different allowances are sometimes related to different countries. A “German” size may then differ from a “French” size, although both countries use the Continental European system.
• Different widths may have the result that for wide feet, a shoe multiple sizes larger (and actually too long) may be required. This may also result in different size indications, especially if different typical widths are attributed to different sizing systems or countries.
• Some tables for children take future growth into account. The shoe size is then larger than what would correspond to the actual length of the foot.
• An indication in centimetres or inches can mean the length of the foot or the length of the shoe's inner cavity. This relation is not constant but varies due to different amounts of wiggle room required for different sizes of shoes.
• There are several U.S. systems, which differ substantially for sizes far above or below medium sizes.

Further, some tables available on the Web simply contain errors. For example, the wiggle room or different zero point is not taken into account, or tables based on different U.S. systems (traditional and athletic) are simply combined although they are incompatible.
