If DIM weight is greater than the actual weight, DIM weight is used instead of the package’s actual weight. If the package volume is less than 1 cubic foot, or the package weight is less than 1lb, then we ignore DIM Weight.
DIM Weight is short for dimensional weight – it’s a billing method that uses the total volume of a package (length x width x height) to calculate shipping costs instead of using the actual weight of the package. Shipping costs are based on the higher of the two measurements: package weight or package size (DIM Weight).
