Understand volumetric weight.
The value of a shipment can be affected by the amount of space it occupies during distribution, rather than the actual weight, which is known as volumetric or dimensional weight.
Actual weight vs. dimensional weight
The value of a shipment can be affected by the amount of space it occupies during distribution, rather than the actual weight which is known as volumetric (or dimensional) weight.
The volumetric or dimensional weight is calculated and compared with the actual weight of the shipment to ascertain which is greater; the higher weight is used to calculate the shipment cost.
