How the Container Loading Calculator works

Maximum cartons is a geometric fit, then constrained by container payload weight.
20ft, 40ft and 40HC each have different internal dimensions and cube.
Utilisation percentage shows how much paid space you are actually using.
Palletised loading trades some cube for handling speed and cargo protection.

Example: Cartons of 40 × 30 × 25 cm into a 40ft: check the loose-load count, then compare it against the palletised count.
