Capacity decision
Physical carton fit is the limiting factor.
Straight-row estimate only. Real loading can be lower because of doors, pallets, mixed sizes, weight distribution and handling clearance.

Frequently asked questions
How many cartons fit in a container?
The count depends on internal container dimensions, carton dimensions, orientation, payload and practical loading constraints.
Does the calculator rotate cartons?
It checks the six simple axis-aligned carton orientations and uses the best straight-row estimate.
Why can actual loading be lower?
Doors, pallets, mixed sizes, weight distribution, damaged space and handling clearance can reduce real capacity.
Can this replace load-planning software?
No. It is a quick estimate for uniform cartons, not a complete three-dimensional packing optimiser.
