How to calculate volume

To determine whether a parcel is more than 2 cubic feet in volume, meaning that the USPS volume surcharge will apply:

• Measure the length, width and height in inches. If the parcel is not rectangular, measure each dimension where it is the largest. For a tube, use the diameter for both the width and the height.
  
  
• Round off each measurement to the nearest inch. For example, if the measurement is at least 6" but less than 6 1/2", round down to 6". But if it is 6 1/2" up to 7", round up to 7".
  
  
• Multiply the rounded length by the rounded width by the rounded height.
  
  
• If the piece is not rectangular, multiply by 0.785.
  

The volume surcharge applies if the result is more than 3,456.
