What is dimensional (DIM) weight?
Dimensional (DIM) weight, also known as volumetric weight, is a calculation created by carriers such as FedEx to apply shipping rates based on a parcel's length, width and height. Dimensional weight takes into account package density to determine shipping rates.
How is dimensional weight calculated?
To calculate dimensional (DIM) weight, multiply the length, width and height of a package, using the longest point on each side. Then, divide the cubic size of the package in inches by the DIM divisor to calculate the dimensional weight in pounds. The DIM divisor is a set number determined by the carrier. Please check the FedEx website or your carrier for information pertaining to the latest DIM divisor.
