FedEx weight limits and size restrictions by service

FedEx has two different ways of calculating the weight of a package: dimensional weight and actual weight.

Dimensional weight, or dim weight, is calculated by multiplying the package's length by width by height (in inches, rounding each measurement to the nearest whole inch) and then dividing by 139.

Dimensional weight = (L x W x H)/139

Actual weight refers to the weight of a package as measured by a scale.

It is important to note that FedEx will charge for whatever weight measurement is higher.

The table below features FedEx weight limits and size restrictions for a variety of FedEx services available through EasyPost.
