Weight, Size, & Shape Requirements
Use USPS Priority Mail Express Flat Rate Envelopes and pay one price:
- Pay the same price for mailpieces weighing up to 70 lbs going anywhere in the U.S.
- When sealing a Priority Mail Express Flat Rate Envelope, the container flaps must be able to close within the normal folds.
Use USPS Priority Mail Express Mailing Boxes and pay by weight and zone (distance):
- Pay for your package based on how much it weighs and how far it’s going (the zone). Maximum weight is 70 lbs.
- Use USPS Priority Mail Express Mailing Boxes that come in standard sizes so you don’t have to worry about measuring them.
Use your own box and pay by weight and zone (distance):
- Pay 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″. Tips for Measuring Packages
- Additional Fees:
- Dimensional (DIM) weight rates apply to large, lightweight packages. If your package is larger than 1 cubic foot (1,728 cubic inches):
- Multiply Length x Width x Height and divide by 166 to get the DIM weight in pounds.
- 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
- Dimensional (DIM) weight rates apply to large, lightweight packages. If your package is larger than 1 cubic foot (1,728 cubic inches):
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.
