Belts should have a couple of inches of leather to the left of the buckle once it’s fastened. There should be enough to tuck under your first belt loop, or the loop on the belt if it has one. The general rule of thumb is to go up 2-4 sizes from your pant size. If you wear a 34″ pant size, a belt labeled 36″-38″ will probably be in the right neighborhood. The amount of leather left over after fastening your belt is merely personal preference but it's always better to err on the side of being short.
