How it works
Space matters as much as scale weight.
Air couriers price a shipment using whichever is greater: its actual scale weight or the space it occupies in the aircraft.
Volumetric weight in kilograms
Length x Width x Height / 5000
Use centimetres for all dimensions.
- 01Measure the final parcel
Measure the outermost length, width and height after the parcel is fully packed.
- 02Calculate dimensional weight
The parcel volume in centimetres is divided by 5000.
- 03Compare both weights
The courier uses the higher of the actual and volumetric weights for rating.
This calculator is a planning estimate. Final billed weight depends on carrier measurement, rounding rules and the booked service.
