How to determine weight of package in Priority mail ?

Postage for parcels addressed for delivery to Zones 1-9 and exceeding 1 cubic foot (1,728 cubic inches) is based on the actual weight or the dimensional weight (as calculated in 1.3.2 or 1.3.3), whichever is greater.

1. Pay the same price for mailpieces weighing up to 70 lbs going anywhere in the U.S.
2. Use our Priority Mail Flat Rate Envelopes or Boxes that come in standard sizes so you don’t have to worry about measuring them.
3. When sealing a Flat Rate Envelope or Box, the container flaps must be able to close within the normal folds.

Determining Dimensional Weight for Rectangular Parcels

Follow these steps to determine the dimensional weight for a rectangular parcel:

1. Measure the length, width, and height in inches. Round off each measurement to the nearest whole inch.
2. Multiply the length by the width by the height.
3. If the result exceeds 1,728 cubic inches, divide the result by 166 and round up to the next whole number to determine the dimensional weight in pounds.
4. If the dimensional weight exceeds 70 pounds, the customer pays the 70-pound price.

Determining Dimensional Weight for Nonrectangular Parcels

Follow these steps to determine the dimensional weight for a nonrectangular parcel:

1. Measure the length, width, and height in inches at their extreme dimensions. Round off each measurement to the nearest whole inch.
2. Multiply the length by the width by the height.
3. Multiply the result by an adjustment factor of 0.785.
4. If the final result exceeds 1,728 cubic inches, divide the result by 166 and round up to the next whole number to determine the dimensional weight in pounds.
5. If the dimensional weight exceeds 70 pounds, the mailer pays the 70-pound price.

Use your own box and pay by weight and zone (distance):

• Any for your package based on how much it weighs and how far it’s going (the zone). Maximum weight is 70 lbs.
• You’ll need to measure your package to make sure it meets the size standards.
• Maximum combined length and girth (girth is the distance around the thickest part) is 108 inches. 
• Additional Fees:
  • Dimensional (DIM) weight rates apply to large, lightweight packages. If your package is larger than 1 cubic foot (1,728 cubic inches):
    1. Multiply Length x Width x Height and divide by 166 to get the DIM weight in pounds.
    2. If the DIM weight is greater than the actual package weight, you’ll need to pay the DIM weight price.
  • If you give inaccurate dimensions and/or don’t pay the DIM weight rate (when it applies), you’ll pay a dimension-noncompliance fee.
  • Nonstandard Fee: You’ll pay an extra fee for sending a nonstandard size if your package measures:
    • Between 22 and 30 inches long: add $4.00
    • More than 30 inches long: add $18.00
    • More than 2 cubic feet (3,456 cubic inches): add $30.00

TIP: Use the USPS^® Price Calculator tool to calculate your domestic postage costs. You’ll need to know your package’s weight, shape, and size measurements.
