My waist size is 36. A size 38 belt gives me about 7 inches from the opening. I'm at the end of hole #4. But I prefer my belt to be a bit longer. Next time I'll take 40 inches. Good quality belt.
Pros
Our belts are measured from the fold where the buckle is to the center hole. If you want to get your best size, please measure the belt that fits you from the crease to the hole where you wear the belt.
