How to Determine Billable Weight


Determine the Actual Weight
Actual weight is the package weight rounded up to the next whole pound. First, use a scale to determine the weight of the package. Round any fraction of a pound to the next whole pound for Express Envelopes (letters) over 8 oz. and all other packages. Letters less than or equal to 8 oz. will be billed the Letter rate. Domestic letters greater than 8 oz. will be billed by weight (rounded up to the next whole pound). Export letters greater than 8 oz. and up to two pounds and international shipments that weigh 2 lbs. or less, do not exceed US$100.00 in customs value, and UPS Express Pak is selected at the time of shipping, qualify for the Pak rate.

Determine the Dimensional Weight
Dimensional weight reflects package density, which is the amount of the space a package occupies in relation to its actual weight. Dimensional weight may apply to all UPS domestic and international package services.

Determine the package dimensions in inches. For each dimension, measure at the longest point, rounding each measurement to the nearest whole number (for example, 1.00 to 1.49 will be considered 1, and 1.50 to 1.99 will be considered 2). Measure the length, width and height of the package at its extreme points. If the package has a bulge or is irregularly shaped, include the bulge or irregular aspects of the package. Multiply the package length by the width by the height. The result is the cubic size in inches.

Note: Refer to UPS's Rate and Service Guide for additional information on measuring irregularly shaped packages.
For Domestic Shipments:
  • UPS Air Services shipments in U.S.: Divide the cubic size in inches by 166 to determine dimensional weight in pounds. Increase any fraction to the next whole pound.
  • UPS Ground shipments in U.S.: If the cubic size of the package in inches is 5,184 or larger, divide the cubic size by 166 to determine dimensional weight in pounds. If the cubic size in inches is less than 5,184, use the actual weight of the package. Increase any fraction to the next whole pound.
Dimensional Weight


For International Shipments
For export and import shipments, divide the cubic size by 139 when measured in inches to determine the dimensional weight. Increase any fraction to the next whole pound.

For import shipments by way of UPS StandardTM from Canada, divide the cubic size in inches by 166 to determine the dimensional weight. Increase any fraction to the next whole pound.

For UPS StandardTM to Canada shipments - If the cubic size of the package is 5,184 cubic inches or greater, divide the cubic size in inches by 139 to determine the dimensional weight. Increase any fraction to the next whole pound.
Dimensional Weight


Notes: Size limits indicated by a box manufacturer may not reflect exterior dimensions of a package, including where a package may have bulges or otherwise may not be uniform across each plane, and should not be used as a substitute for actual length, width, and height measurements in determining dimensional weight.

Improper packaging may result in the alteration of a package's dimensions during transit which can affect the package's dimensional weight and result in a shipping charge correction.

Determine the Billable Weight
Compare the package's actual weight to its dimensional weight. The greater of the two 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.

A Large Package Surcharge may apply to domestic and international shipments. A package is considered a "Large Package" when its length plus girth [(2 x width) + (2 x height)] combined exceeds 130 inches.

Large Packages are subject to a minimum billable weight of 90 pounds. An Additional Handling charge will not be assessed when a Large Package Surcharge is applied.
