Dimensional weight, also known as volumetric weight, is a pricing technique for commercial freight transport (including courier and postal services), which uses an estimated weight that is calculated from the length, breadth, and height of a package. The shipping fee of your courier is based upon the dimensional weight or the actual weight, whichever is greater.
Volumetric Weight vs Actual Weight
The following image will give you a more visual idea of volumetric weight.
Courier will choose the higher value when choosing between the actual weight and the volumetric weight. This means that even if your package weight is 0.8kg (the actual weight), if the volumetric weight is 4 kg, then the rate for 4kg will be charged.
How to Calculate Volumetric Weight for International Courier
To get the volume of a box, multiply its length, width, and height and divide it by 5000; the outcome of this sum is the volume weight of the box. Measuring the dimensions of a parcel in centimeters is common in the courier world.

How To Reduce The Volumetric Weight Of Your Parcel?
While packing, make sure that the box is not bulging out from any side. Always use the right size box to pack your items. If you have bulky things, like a quilt, pillow, teddy bear, etc, vacuum pack them – this will save a lot of space. Do not leave any loose space inside the box – so it doesn’t swell in transit.
