Dim Weight Calculator

Dimensional weight, also called “dim” weight, is used because the space a package takes on an aircraft may cost more than the package's actual weight. You should calculate dimensional weight on every shipment, compare that to its actual weight, and use the greater of the two to determine your shipping cost. International and domestic dimensional weights are calculated differently using the formulas below.

For Domestic and International Shipments:

L x W x H (cubic inches) / 139 = Dimensional Weight.

Example: 30” x 24” x 22” = 15,840 / 139 = 114 lbs. (round up to the next pound) Volumetric weight dimensions

The Dimweight is given in pounds.
