Container Load Calculator
Free container calculator for exporters. See how many cartons fit in a 20ft, 40ft, 40ft high cube, or 45ft high cube, and how many boxes a shipment needs. This is a plan, not a loading guarantee.

Usable planning volume, not the empty box: about 28 of 33 CBM for a 20ft, 58 of 67 for a 40ft, 68 of 76 for a 40ft high cube, and 72 of 86 for a 45ft high cube. Payload and pallet gaps cut the real load.
How to use it
- Enter the outer size of one carton.
- Enter how many cartons you need to ship.
- Read cartons per container type and how many boxes you would need.
How the figure is worked out
Cartons that fit = usable CBM ÷ CBM of one carton. Planning capacity used here is below the empty-box volume: 28 of about 33 CBM (20ft), 58 of about 67 (40ft), 68 of about 76 (40ft high cube), and 72 of about 86 (45ft high cube).
Questions
Why might fewer cartons fit than this shows?
Door height, pallet overhang, weight limits, and awkward sizes reduce the load. Treat this as a first plan, then confirm with your forwarder.
Why is the CBM below the empty container size?
An empty 20ft is about 33 CBM, but usable cargo space is closer to 28. This sheet uses those usable figures so the plan is not the empty box.
