Dimensional Weight Calculator

What is Dimensional Weight?

Dimensional weight (DM), often called volumetric or cubed weight, is a pricing method used by carriers and shipping companies to calculate charges. Instead of just looking at how much a package weighs, they also consider how much space it takes up and charge you for the heaviest one.

 

This means that if you’re shipping something light but bulky, you’ll be charged based on its size rather than just its weight.

How to Calculate Dimensional Weight?

The formula to calculate dimensional weight is:

DIM weight = (Package Length × Package Width × Package Height) / Carrier's DIM factor
 
Let's break it down:
 
1. Measure the Package
 
Measure the length, width, and height of your package in inches. Make sure you measure from the longest points on each side.
 
2. Calculate the Cubic Size
 
Multiply the length, width, and height to get the cubic size of the package.
 
4. Determine Dimensional Weight
Divide the cubic size by the dimensional factor (dim divisor). The divisor varies by carrier. Use the list below or our calculator.
 
5. Compare with Actual Weight
 
Compare the dimensional weight to the actual weight of the package. The shipping cost will be based on the greater of the two weights.
