Men's Clothing Size Conversions

Clothing sizes in the United States are different than those found in most other countries. If you are a visitor from another country shopping for clothes in the USA, it might be useful to know the differences in US sizes. This page is designed to be a useful tool in converting local sizes to approximate US sizes. We try to keep the data as accurate as possible, but we cannot guarantee that it is absolutely correct. Sizes of clothing vary between manufacturers and even between different designs by the same manufacturer. You should use these charts for approximation only.
