As the final part of the affected changes to the Mailing Standards of the USPS earlier this year, the United States Postal Service will implement Dimensional Weight (DIM) weight pricing as of June 23, 2019.

This change in calculating shipping for larger packages makes it crucial for sellers to optimize packaging if they ship medium to large packages that contain potentially lighter items. If you can reasonably fit items into a smaller package, you'll absolutely want to explore your options.

Which Services are Affected?

All zones for Priority Mail, Priority Mail Express and Parcel Select.

How is DIM weight calculated?

DIM weight is determined by multiplying a package's length, width, and height and applying a volumetric divisor.
