Dimensional weight is estimated by multiplying box length x width x height in inches, then dividing by the DIM divisor used for the shipment. Carriers and services can use different divisors, so confirm the current rule with the carrier or rate tool before quoting freight. Use this calculator to compare box sizes and avoid paying for more empty space than the product needs.
Dimensional weight estimates how much space a parcel takes up. Use it to avoid choosing a box that is much larger than the product needs.
