Understanding dimensional weight

Dimensional weight applies to both FedEx Express® and FedEx Ground® packages. It reflects a package’s density, which is the amount of space a package occupies in relation to its actual weight. For each shipment, your charge is based on the dimensional weight or actual weight of the package — whichever is greater.*

For final Rated Weight and charges, please refer to the FedEx Service Guide and, if applicable, your FedEx contract.

*FedEx reserves the right to re-weigh and measure each package to verify the actual weight and dimensional weight provided by the sender. If the dimensional weight exceeds the actual weight, the package will be rated based on dimensional weight and subject to additional charges.
