Dimensional Weight is a pricing structure that takes into account a package's box dimensions as well as the package weight. As e-commerce sales grow, shipping carriers are running out of space on their delivery trucks and they want to make sure retailers are using the smallest box to fill their trucks with as many packages as possible.

While other national carriers apply DIM Weight for all package sizes, the USPS only uses DIM Weight for packages over one cubic foot for Priority mail, Priority Mail Express, and Parcel Select Packages.

Online retailers whose products are light weight and larger in size (i.e. larger plastic toys, sports equipment, pillows, bubble wrap) will likely pay the DIM Weight price instead of the standard, physical weight price. If a package's calculated Dimensional Weight is more than the physical weight, the shipper is required to pay the Dimensional Weight rate.

But how is dimensional weight calculated?
