Space on an aircraft is limited, so airlines charge by chargeable weight: the higher of the actual gross weight and the volumetric (dimensional) weight.
Calculating volumetric weight
Volumetric weight (kg) = L × W × H (cm) ÷ 6000
A carton measuring 60 × 40 × 40 cm has a volumetric weight of 16 kg. If it actually weighs 10 kg, you pay for 16 kg.
How to reduce it
- Use right-sized cartons to cut empty space
- Avoid oversized packaging and fillers
- Consolidate small parcels into fewer cartons
Our CBM calculator shows both volumetric and chargeable weight instantly.
