Weight, Size, & Shape Requirements

- You’ll need to measure your package to make sure it meets the size standards.
- Maximum weight is 70 lbs and maximum combined length and girth is 130 inches. 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 $7.00
- More than 2 cubic feet (3,456 cubic inches): add $15.00
- 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.
