I wear trousers with a waist size of 34 and ordered a size 35 belt first, which was a bit small. The size 35 belt was tight around my waist, but once it was on it had a not long enough tail. I sent the belt back and ordered a belt size 39. This size was about 1 inch longer, but the package includes instructions and a handy leather punch to reduce the length of the belt. There is a screw on the buckle that can be unscrewed to cut off the excess length. The leather quality is thick and I expect this belt to last for many years. This belt is way better than any you will find at your local retail store.
