B.B. Simon belts are measured from the inside edge of the buckle to where it clasps the middle belt hole. Each belt has 5 belt clasp holes shown as red dots in the belt measurement photo below. All measurements are in inches.
Waist Measurement:
When picking a size please account for where on your waist you plan to wear the belt as well as the thickness of the clothing you plan to wear with the belt. Jean sizing and belt sizing are not the same as clothing thickness can impact the waist measurement.
How To Measure Your Waist:
You can measure your waist by wrapping a tape measure around your waist while wearing the clothing you plan to wear under the belt. Make sure that the tape measure is placed where you plan to wear the belt. You can then use this measurement to choose the appropriate size.
