About USPS and UPS package sizes
In this article

When you create your listing, you can provide your package size and weight, and select a choice of up to three types of shipping services. Our shipping calculator uses that information to provide the shipping cost to buyers and bidders.

Package (or thick envelope)

  • A package is a parcel (or box) less than 84" when you add the length plus girth. Length is the longest side of a package. Girth is the distance around the 2 smaller sides of a package.

  • A thick envelope is a large envelope exceeding 3/4" thickness.

Note: For large UPS packages, you might need to enter dimensions to correctly calculate costs.

Large Package

A large package is a parcel (or box) whose length plus girth is over 84" and less than or equal to 165". Length is the longest side of a package. Girth is the distance around the 2 smaller sides of a package.

Note: For large UPS packages, you might need to enter dimensions to correctly calculate costs.

Packages with length plus girth between 130" and 165" can only be sent through UPS. To help you determine that a package is within UPS limits, a 130-inch chain is available by calling 1-800-PICK-UPS.
