Fedex Dim Weight Calculator

FedEx Dim Weight Calculator is a handy tool that helps you determine the dimensional weight of your package for FedEx shipments. Dimensional weight, also known as dim weight, is a pricing technique used by shipping carriers to account for the space a package occupies in relation to its actual weight. This calculator simplifies the process, providing quick and accurate dim weight calculations.

Formula: The dimensional weight is calculated using the formula: Length x Width x Height / 166. The result is then compared with the actual weight of the package, and the higher of the two is considered the billable weight.

How to Use:

  1. Enter the length, width, and height of your package in inches.
  2. Input the actual weight of the package in pounds.
  3. Click the “Calculate” button to obtain the FedEx dimensional weight.

Example: Suppose you have a package with dimensions 12″ x 10″ x 8″ and an actual weight of 3 lbs. After entering these values and clicking “Calculate,” the tool will display the FedEx dimensional weight.
