How Does Amazon Calculate Dimensional Weight?
Amazon calculates dimensional weight using package dimensions instead of actual product weight when larger packages consume more shipping space. Dimensional weight affects oversized inventory, lightweight bulky products, packaging optimization, shipping efficiency, and storage cost.
