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

 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.

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

 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. 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. For the dimensional weight of your package in kilograms, divide the cubic size of your package in centimeters by 5,000. Increase any fraction to the next whole kilogram. 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. For multiple-package shipments total the billable weight of all packages in the shipment. For import shipments: 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. For the dimensional weight of your package in kilograms, divide the cubic size of your package in centimeters by 5,000. Increase any fraction to the next whole kilogram.

 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 size of 165 inches (419cm).

 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.
