To correctly determine belt size, take a measurement around waist or hips in the position you intend to wear the belt. This will usually be a few inches larger than your pants size as the belt needs to account for material thickness of clothing. Belt sizing is taken from centre hole to the buckle tongue, with additional adjustment 2 holes either side of waist measurement. Please check and confirm this measurement before you order. Traditional unit is inches; please specify if you prefer centimeters.
