Dimensional Weight

If your package has a large size-to-weight ratio, you should consider your package's dimensional weight when calculating your shipping rates.

Learn About Dimensional Weight

Determining which weight to use in calculating your rate requires that you determine which rule applies. Dimensional weight reflects package density, which is the amount of space a package occupies in relation to its actual weight. Dimensional weight may apply to all UPS domestic and international services. Billable weight is the weight used to calculate the rate. For domestic and international services, the billable weight will be the greater of the dimensional weight as compared to actual weight. Calculations of dimensional weight are subject to change without notice.

Packages that exceed UPS weight and size limits are not accepted for transportation. If found in the UPS system, they are subject to an Over Maximum Limits charge.

How To Measure the Cubic Size of Your Package

Calculate the cubic size of your package in inches by multiplying the height (number 1 in the diagram), by the length (number 2 in the diagram), by the width (number 3 in the diagram). Round each measurement to the nearest whole inch. The resulting total is the cubic size of your package.

How To Calculate Dimensional Weight

You can calculate the dimensional weight as the billable weight when the dimensional weight of your package exceeds its actual weight.

  • Determine Actual Weight: Use any standard scale to determine the actual weight of your package. Increase any fraction to the next whole pound.
  • Determine Dimensional Weight: Divide the cubic size of your package in inches by 139 to determine the dimensional weight in pounds. Increase any fraction to the next whole pound. 
  • Determine Billable Weight: Compare the package's actual weight to its dimensional weight. The larger of the two weights is the billable weight and should be used to calculate the rate.

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

Large Package Surcharge

A Large Package Surcharge will be applied to each UPS package when its length plus girth [(2 x width) + (2 x height)] combined exceeds 130 inches, but does not exceed the maximum UPS size of 165 inches.

Large Packages are subject to a minimum billable weight of 90 pounds in addition to the Large Package Surcharge.

An Additional Handling charge will not be assessed when a Large Package Surcharge is applied.
