For a pin buckle belt, your size is typically measured from the start of the leather strap (where it meets the buckle) to the middle hole. The best way to find your ideal size is to:

Measure Your Waist: Measure your waist at the level you wear your pants. Generally, your belt size will be 1-2 inches larger than your pant size. Aim for a size where you can comfortably use the middle hole, allowing room for adjustment.

Measure an Existing Belt: Lay a well-fitting belt flat and measure from the tip of the buckle’s prong to the hole you use most often.
