Dim weight reflects package density, which is the amount of space a package occupies in relation to its actual weight. All FedEx Express and FedEx Ground shipments within the U.S., U.S. import-rated international shipments, and U.S. export shipments are subject to dim weight rating.

Billable weight is the weight used to calculate your rate. For domestic and international services, the billable weight will either be the dim weight or the actual weight of your package (whichever number is greater). Calculations of dim weight are subject to change without notice. See the FedEx Service Guide for more details on dim weight.

Dim weight is calculated based on the length, height, and width of the package. The dim weight becomes the billable weight when the dim weight of your package exceeds its actual weight.

Follow these easy steps to calculate dim weight:

1.   Calculate the cubic size of your package in inches. Round each measurement of your package to the nearest whole inch. Multiply the length by width by height of your package. The resulting total is the cubic size of your package. 

2.   Determine actual weight. Use any standard scale to determine the actual weight of your package. Increase any fraction to the next whole pound.

3.   Determine dim weight. Divide the cubic size of your package in inches by 139. Increase any fraction to the next whole pound. 

4.   Determine billable weight. Compare the package's actual weight to its dim weight. The larger of the two weights is the billable weight and should be used to calculate the rate.

5.   For multiple-package shipments, total the billable weight of all packages in the shipment.

Recent e-commerce shipping trends have led to a decrease in package density. The average package weight compared to its exterior dimensions is declining, which is inefficient and costly for small businesses. Dim weight pricing methods will encourage businesses everywhere to optimize their packaging practices.

Packing properly may boost your bottom line. Many businesses use a few standard box sizes for all shipments without realizing the impact of dim weight on their shipping costs. FedEx can help you analyze your typical shipments and determine the right variety of box sizes necessary to protect your products without wasted dim weight. 

There are a number of reasons why the rates on your invoice may be different from your rate quotes. For example, the service type or the amount of information entered may differ. Another possible answer is that the package dimensions were not included in the estimate, but the package dimensions do affect the actual shipping cost.

For offline devices like FedEx Ship Manager® Server and FedEx Ship Manager® Software, the most common answer is that the automation device has not downloaded the most recent rate file.

For online devices like FedEx Web Services and fedex.com, it’s possible that the entered order weight was different from the actual. For further clarification please contact Customer Service at 1.800.GoFedEx 1.800.463.3339.
