Your Shipping Result
Couriers charge based on the greater of actual or dimensional weight.
Understanding Dimensional Weight
When shipping packages via major couriers like FedEx, UPS, or DHL, you aren't just charged by how heavy your box is. If you ship a very lightweight item in a massive box, it takes up valuable space on their planes and trucks. To account for this, couriers use Dimensional (DIM) Weight.
Your "Billable Weight" is always the greater of the Actual Weight or the Dimensional Weight.
How it is Calculated
Multiply Length × Width × Height to get the volume, then divide by the correct DIM Divisor. For US domestic shipments in inches, FedEx and UPS typically use 139. For international metric shipments in cm, 5000 is often used.
Stop Paying for Air
If your dimensional weight exceeds your actual weight, you are essentially paying to ship empty space. Using correctly sized packaging is the single best way to lower your shipping rates.
