Shipments are priced either by weight or dimensional weight — a calculation based on package size.
To find dimensional weight, multiply the length, width, and height of your package in inches OR centimeters, rounded up to the nearest whole number. This is your cubic size.
For measurements in INCHES, divide cubic size by 139 to find dimensional weight in POUNDS.*
For cubic size made in CENTIMETERS, divide by 5,000 for dimensional weight in KILOGRAMS.
Compare dimensional weight to the actual weight of your package. The larger number determines your shipping charges, so if you have a lightweight item packed in an oversize container, consider using a smaller box if possible.
*NOTE: For shipments within the U.S. and imports to the U.S. from Canada, divide cubic size in inches by 166.
