I have a 35 waist and bought 32-36 inch belts. They were WAY to big.I returned those and ordered the 28-32 inch belts and they fit perfectly.Remember I'm 35 inch waist.
Pros
Suggest you order shorter because of itβs stretching ability.
Cons
The buckle may not be strong enough to support a heavy load, such as a backpack or luggage
