How to Determine Billable Weight
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 compared to the actual weight.

Determine the Actual Weight
Actual weight is the package weight rounded up to the next whole pound.

Use a scale to determine the weight of the package. Round any fraction of a pound to the next whole pound for UPS Express® Envelopes (letters) over eight ounces and all other packages.

Determine 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).

Multiply the package length by the width by the height. The result is the cubic size in inches.
For Domestic Shipments:
Divide the cubic size in inches by 166 to determine dimensional weight in pounds. Increase any fraction to the next whole pound.
Dimensional Weight

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

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

Determine 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.

Additional Information on Determining Weight and Size

Letter rates apply for domestic and international documents, correspondence and electronic media shipments that do not exceed eight ounces sent in a UPS Express® Envelope. Domestic letters greater than eight ounces will be billed by weight (rounded up to the next whole pound). Export letters greater than eight ounces and up to two pounds will be billed at UPS Express® Pak rates. Export letters greater than two pounds and import letters greater than eight ounces will be billed by weight (rounded up to the next whole pound).

UPS Express Pak rates apply for export shipments that weigh two pounds or less, do not exceed $100.00 in customs value and UPS Express Pak is selected at the time of shipping.

Irregularly Shaped Packages: If the package has a bulge or is irregularly shaped, measure the length, width and height of the package at its extreme points, which may include the bulge or irregular aspects of the package. Treat the irregularly shaped package as if it were in a regular rectangular box. Measure the length, width and height of the package from its extreme points.

Items Shipped in Bags:

  • Shape - When multiple items are shipped in a flexible container (e.g., burlap or plastic bag), the package measurements will be determined when the exterior is at rest. As this shape will differ from placement to placement, cubic size or package measurements will be made at the sole discretion of UPS.

  • Tails - A tail on an item shipped in a bag should be measured for the amount of space it takes up in a reasonably compressed fashion. Any tail that is created by placing an item in a bag must be compressed and taped to the body of the item.

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.

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.

Shippers are responsible for providing accurate and complete shipment information on the shipping document or in the automated processing system used, including service selected, number, weight and dimensions of packages. UPS reserves the right to audit any package and/or invoice to verify service selection, package dimensions or weight and applicability of any charges. As part of that audit, UPS may weigh and measure any package tendered to UPS using any method UPS deems appropriate including, but not limited to, multidimensional measuring devices. If any aspect of the shipment information provided by the shipper is incomplete or incorrect as determined by UPS in its sole and unlimited discretion, UPS may in its sole and unlimited discretion adjust charges at any time.

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.
