Dimensional weight calculator

Calculate volumetric weight and cubic metres from a carton size. Use it to sanity-check quotes before sending a parcel or a freight inquiry.

The divisor differs by carrier, service, origin, and contract. Check the quote and bill before charging a customer.

Why dimensional weight matters

Shipping networks charge for space as well as mass. A light but bulky parcel may be billed by the dimensional result, so carton design is part of product margin.

Formula

For centimetres, dimensional weight in kilograms is length multiplied by width multiplied by height, then divided by the carrier divisor. CBM is length multiplied by width multiplied by height, then divided by one million.
