As e-commerce continues to grow, shipping packages of all shapes and sizes has become more common. While this is great news for consumers, it presents a unique challenge for shipping carriers like FedEx and UPS. To accurately charge customers for the shipping space they’re using, both FedEx and UPS have implemented a pricing model called “dimensional weight” (also known as “dim weight”).

What is Dimensional Weight?

Dimensional weight is a calculation that determines the “density” of a package and its impact on shipping costs. It takes into account both the weight of the package and its size, and is used to ensure that customers are charged fairly for the shipping space they’re using. Essentially, if a package is large but lightweight, its dimensional weight will be higher than its actual weight, and this is what the shipping carrier will use to calculate shipping costs.

How is Dimensional Weight Calculated?

The calculation for dimensional weight is straightforward. To determine the dimensional weight of a package, the carrier takes the length, width, and height of the package and divides it by a “dim factor”. This dim factor is set by the carrier and is used to convert the package’s cubic size into weight.

For FedEx and UPS, the dim factor is 139. So, if a 5 pound package measures 10 x 10 x 10 inches, its dimensional weight would be 8 pounds (10 x 10 x 10) / 139 = 7.19, which is rounded up to the nearest pound. This means that even though the package may only weigh 5 pounds, the customer will be charged for shipping based on its dimensional weight of 8 pounds.

How Does Dimensional Weight Affect Shipping Costs?

Dimensional weight affects shipping costs because carriers charge based on the greater of either the actual weight of the package or its dimensional weight. This means that if a package has a high dimensional weight, it will cost more to ship than if its actual weight was higher. This is because carriers are trying to balance the costs of shipping a large, lightweight package with the space it takes up in their trucks and warehouses.

For customers, this means that it’s important to pay attention to dimensional weight when calculating shipping costs. By optimizing the size and weight of packages, it’s possible to minimize shipping costs and ensure that you’re not paying more than you need to.

In conclusion, dimensional weight is a pricing model used by FedEx and UPS to ensure that customers are charged fairly for the shipping space they’re using.
