Determining Priority Mail Express Dimensional Weight
Priority Mail Express dimensional weight for rectangular shaped parcels to zones 1–9.
- Measure the length, width, and height in inches. Round off 1 each measurement to the nearest whole inch:
(length = 21, height = 20, and width = 20).
- Multiply length x height x width: (21 x 20 x 20) = 8,400 cubic inches.
- If the result exceeds 1,728 cubic inches, divide the result by 166 and round up2 to the next whole number to determine dimensional weight in pounds:(8,400/166 = 50.60) 50.60 rounded up to the next pound is 51.
- The price is based on the actual weight or dimensional weight, whichever is greater.
In this example the dimensional weight for this rectangular package to zones 1–9 is 51 pounds.
Priority Mail Express dimensional weight for nonrectangular shaped parcels to zones 1–9.
- Measure the length, width, and height in inches at their extreme dimensions. Round off1 each measurement to the nearest whole inch: (length = 30, height = 9, and width = 18).
- Multiply length x height x width: (30 x 9 x 18) = 4,860 cubic inches.
- Multiply the result by an adjustment factor of 0.785: 4,860 x 0.785 = 3,815.1 cubic inches.
- If the final result exceeds 1,728 cubic inches, divide the result by 166 and round up2 to the next whole number to determine the dimensional weight in pounds: (3,815.1/166 = 22.98) 22.98 rounded up to the next pound is 23.
- The price is based on the actual weight or dimensional weight, whichever is greater.
- If the dimensional weight exceeds 70 pounds, the package pays the 70 pound price.
In this example the dimensional weight for this nonrectangular package to zones 1–9 is 23 pounds.
Additional examples of nonrectangular measurement.
1. Round off (e.g., 20.5 rounded off to the next whole number is 21, and 20.4 rounded off is 20), see 604.7.1.3.
2. Round up (e.g., rounding up either 44.2 or 44.8 to the next whole pound is 45).
