Dimensional Weight
If your package has a large size-to-weight ratio, you may need to consider your package's dimensional weight when you calculate your shipping rates.


Learn About Dimensional Weight
Determining which weight to use in calculating your rate requires that you determine which rule applies. Different rules apply depending on the service selected. Dimensional weight considers density, which is the amount of space a package occupies in relation to its actual weight, to determine billable 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 by multiplying the height in inches or centimeters, by the length in inches or centimeters, by the width in inches or centimeters. Round each measurement to the nearest whole inch or centimeter. The resulting total is the cubic size of your package.

Calculating Dimensional Weight for Domestic Shipments
If you have more than one package to be shipped, consider each package a separate shipment for weight calculation purposes.

Determine the Actual Weight: Use any standard scale and round up any fraction of a pound to the next full pound.

Determine Dimensional Weight:

  • For UPS Ground Shipments: If the cubic size of the package is 5,184 or larger, divide the cubic size by 194 to determine dimensional weight in pounds. If the cubic size is less than 5,184, use the actual weight of the package.
  • For UPS Air Shipments: Divide the cubic size by 194 to determine dimensional weight in pounds. Any fraction of a pound will be calculated at the next highest rate.

Determine Billable Weight: Compare each 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.

If you have a multiple-package shipment, add the cubic sizes for all of the packages together. The total is the cubic size of your shipment.

Large Package Conditions
Your UPS package is considered a Large Package when its length plus girth [(2 x width) + (2 x height)] combined exceeds 130 inches (330cm), but does not exceed the maximum UPS size of 165 inches (419cm).

Large Package Surcharge
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 (330cm), but does not exceed the maximum UPS size of 165 inches (419cm).

Large Packages are subject to a minimum billable weight of 90 pounds (40kgs) in addition to the Large Package Surcharge.

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

Calculating Dimensional Weight for International Shipments
Use dimensional weight as the billable weight when the dimensional weight of your packages exceeds their actual weight, for your international shipments using these services:

  • UPS Worldwide Express PlusSM
  • UPS Worldwide ExpressSM
  • UPS Worldwide SaverSM
  • UPS Worldwide ExpeditedSM
  • UPS 3 Day SelectSM from Canada
  • UPS Standard

Follow these guidelines to determine your shipping rate:

Determine Actual Weight: Use any standard scale and round up any fraction of a pound to the next full pound.

Determine Dimensional Weight:

  • For export shipments using UPS Worldwide Express, UPS Worldwide Saver, and UPS Worldwide Expedited: Divide the cubic size by 166 if measured in inches, or by 6,000 if measured in centimeters, to determine the dimensional weight. To convert metric measurements into pounds, multiply the result by 2.20462. Any fraction of a pound will be calculated at the next highest rate. 
  • For import shipments: Divide the cubic size by 139 if measured in inches, or by 5,000 if measured in centimeters, to determine the dimensional weight. To convert metric measurements into pounds, multiply the result by 2.20462. Any fraction of a pound will be calculated at the next highest rate. For import shipments from Canada, Puerto Rico, and U.S. Virgin Islands, divide the cubic size by 166 if measured in inches, or by 6,000 if measured in centimeters.
  • For UPS Standard shipments: If the cubic size of the package is 5,184 cubic inches (84,951 cubic centimeters) or greater, divide the cubic size by 166 if measured in inches or by 6,000 if measured in centimeters, to determine the dimensional weight. To convert metric measurements into pounds, multiply the result by 2.20462. Any fraction of a pound will be calculated at the next highest rate. If the cubic size is less than 5,184, use the actual weight of the package.

Determine Billable Weight:
Compare each package's/shipment'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.
Calculating Dimensional Weight


Note: To calculate dimensional weight for import shipments, divide the cubic size by 139 if measured in inches, or by 5,000 if measured in centimeters. For import shipments from Canada, Puerto Rico, and U.S. Virgin Islands, divide the cubic size by 166 if measured in inches, or by 6,000 if measured in centimeters.
