Dimensional weight, also known as DIM weight, volumetric weight, or cubed weight, is universally applied in the transportation industry to establish shipping costs based on the amount of space a shipment consumes, rather than its actual weight. Dimensional weight is calculated as length x width x height, divided by the applicable dim factor, and is applied for rating purposes when the DIM weight calculation is greater than the shipment’s actual weight. Dim factors used to determine DIM weight vary by carrier, however they are generally 194 for domestic air freight, 166 for international air freight, and 250 for ground transportation.
