# What is Dimensional Weight Pricing (DIM)?

FFI makes our clients’ e-commerce integrations easy by integrating their online shops with our Order Management System (OMS), creating streamlined, automated flows for orders to be received, processed and shipped direct to customers.

In simple terms, DIM weight pricing is a way of calculating the fee associated with shipping a parcel based on that parcel’s size. The purpose of dimensional weight pricing is to take into account the cubic volume of the package in relation to the parcel’s actual weight. Businesses freight charges are no longer just calculated by how much their packages weigh, the new algorithm also calculates freight charges by how much space the package takes up on the truck or plane.

## Carrier space is prime real estate and is priced as such.

With online shopping growing by leaps and bounds each year, carriers put tremendous value on the amount of space available in a truck, trailer or delivery van. Carriers want to discourage shippers from sending out oversized containers that are mainly packing materials, so shippers need to begin packing their products more efficiently so carriers are able to load more packages into the available space on each vehicle of transport. Packages that fail to meet these guidelines will cost more to ship.

## DIM pricing, how is it calculated?

Dimensional weight pricing is calculated by dividing the volume of your package by the DIM factor, which is a mathematical constant that is considered as the base weight of one cubic foot of space and is correlated with a specific number given by each carrier.

THE DIMENSION WEIGHT CALCULATION = (Length x Height x Width)/DIM Factor

Using this calculation, freight carriers like FedEx, USPS or UPS calculate shipping charges based on whichever of the following numbers is greater: 1) the actual weight of the package or 2) its calculated dimensional weight. Whichever number is higher becomes your billable weight.

For example, if you are shipping a plush toy such as a stuffed teddy bear in a 12”x12”x12” box, the actual weight of the stuffed teddy bear, box and filler might add up to a total weight of 5 pounds. However, when you multiply the package dimensions and divide by the UPS or FedEx DIM factor of 166, the package’s dimensional weight comes out to 10 pounds which, because it’s the higher number, is how you’ll be billed.

Actual Weight = 5 pounds < 10 pounds DIM Weight

The current DIM divisor of DHL is 139, while UPS and FedEx are both 166. For international shipping, the DIM factor of both UPS and FedEx is 139. So imagine you were shipping that same plush teddy bear overseas using UPS or FedEx. Your DIM factor would be lower but your billable weight would be higher.

Actual Weight = 5 pounds < 12 pounds DIM weight

Essentially, the higher the DIM factor, the lower the dimensional weight and vice versa.
