When shopping for trousers in Europe, it is important for Americans to understand how to convert their American pant size into European sizing standards. For men, this is much simpler because most men's clothing is sized by actual body measurements. Smaller American men will have an easier time finding trousers that fit without alterations because European men tend to be smaller than American men. For women, plus size women and junior's, converting American size to European size in trousers takes a little more work.
American misses sizes range from a size 2 to a size 14. For women who wear misses sizes, converting from your American size to European size simply requires adding 30 to your American size. For instance, if you wear a size 6 trousers in American size, you would wear a size 36 in European size trousers. If you are 5 foot 3 inches or shorter, you will most likely fall into the category of petite. In this case, the pant size would have a "P" next to it, such as 36P.
Women's American sizes 16 to 28 generally fall into the category of plus sizes. Most women who are over a size 28 will require specially ordered or made trousers. Plus size women's pant conversions work the same as misses pant sizes. For example if you wear a size 20 trousers in American sizes, you add 30 to get your European size, making your European size a 50.
Juniors-sized trousers are made to flatter the bodies of teenagers and younger women. In U.S. clothing, juniors sizes come in odd numbers ranging from 1 to 15. To find your juniors size in European clothing, first you subtract 3 from your American pant size, and then you add 30. So, if you wear a size 5 in U.S. trousers sizing, your European trousers size would be 32.
Both in Europe and in the United States, men's trousers are sized by the waist measurement and the inseam measurement. The only difference between American and European trousers sizes is that the European trousers sizes may sometimes be in centimetres and not inches. To calculate your trousers size in centimetres, simply multiply your waist measurement and your inseam measurement by 2.54. For instance, if in American sizes you wear a 30 by 32 in European size trousers this would be a 76 by 81. When you multiply by 2.54 you will also get a decimal in your calculation, you can round up or round down depending on how you like your trousers to fit.
