Dimensional Weight Calculator

What is dimensional weight and why is it used? Dimensional weight is the amount of space a package occupies in relation to its actual weight. Shipping carriers implemented this to incorporate the size of a package into the pricing structure. All carriers base their rates on weight and distance (zones); so, a package will be weighed and then the dimension will be taken, whichever is “heavier” will be used to determine the shipping cost for a package.

Enter the dimensions of your box into the Dimensional Weight Calculator to better understand what could be impacting your shipping costs.
