What is volumetric weight?

Volumetric weight (also called dimensional weight or DIM weight) is a pricing technique carriers use for lightweight, low-density packages. Without it, a large box of pillows would ship for the same cost as a small box of bricks — even though the pillows take up far more space on the plane or truck.

The formula divides the package volume by a carrier-specific divisor:

volumetric weight = (L × W × H) / divisor

Carriers charge whichever is greater: actual weight or volumetric weight.
