About this container loading calculator

How does it work?

The calculator packs your carton size onto the container floor using grid and mixed-orientation patterns, stacks layers to the ceiling, and applies the container's payload limit — showing the result in 3D.

Which containers are covered?

20ft, 40ft, 40ft high cube, 45ft high cube, 20ft/40ft reefers and 40ft open top, using standard ISO interior dimensions. Each has a dedicated page with full specs — see the links below.

Shipping palletized cargo?

Plan cartons per pallet with the pallet load calculator, then check pallets per container on the 40ft or 20ft container pages. For volume-based quotes use the CBM calculator.
