A good rule of thumb for a great fit is to select a belt that is at least 2 inches larger than your waist size (in.). If your waist size is an odd number, increase the belt size by 3 inches, e.g. a waist size 27 should wear a size 30 belt. This is what we find works for the majority of our customers.
