What is Volumetric Weight?

Volumetric weight (also known as dimensional weight) is a calculation used by logistics companies to account for light, bulky packages. A large box filled with bubble wrap takes up more space in a cargo airplane or delivery truck than a small iron weight. To ensure fair billing, couriers measure dimensions and convert the total volume into a weight equivalent using a standard divisor.

The Volumetric Formula:

Dimensions in centimeters are multiplied and divided by a standard density ratio (IATA divisor):

Volumetric Weight = (Length × Width × Height) / Divisor

* The divisor 5000 is standard for domestic couriers (Delhivery, Shiprocket, Bluedart). Air cargo often uses 4000.

How to Optimize Packaging:

  • Choose box sizes closest to the product's actual dimensions.
  • Use bubble mailers or polybags for flat, non-fragile items (these have no height volume).
  • Cross-check courier invoices against your warehouse records to identify illegal dimensional overcharges.
