How it works
The calculator tries each carton side as the height, then fits the most cartons on the floor using straight rows plus a block turned the other way when that fits more. Layers stack to the container's inside height.
Real loads lose a little space to door clearance, bracing and uneven cartons, so allow a few percent. Payload limits differ by container; check the CSC plate on the door.
Frequently asked questions
How many cartons fit in a 20 ft container?
It depends on the carton size. For 60 × 40 × 40 cm cartons, about 255 fit in a 20 ft standard container. The volume alone suggests 345, but cartons can't fill every gap along the walls and roof.
What are the inside dimensions of a 40 ft container?
About 12.03 m long, 2.35 m wide and 2.39 m high, or 2.70 m high for a high cube.
