US Trousers sizing system
Widths
Trouser width is measured from your waist.
Military trousers are worn high, measure yourself at the navel.
The difference between two adjacent sizes on this system is 10 cm or 4 inches.
The table below shows the waist width in centimeters for each size. If your waist is equal or below the number on the table, take that size, if it is bigger, take one size up. Don't order one size bigger just to be sure - you'll end up with really big trousers!
