How this calculator works
Capacity checks all six right-angle carton orientations against nominal internal container dimensions and selects the highest grid count.
Worked example
A 60 × 40 × 35 cm carton can be compared in all orientations; the highest mathematical grid is shown before loading losses.
How to measure
- Use external carton dimensions.
- Allow space for dunnage and loading access.
- Verify the specific equipment supplied by your carrier.
Common mistakes
- Treating theoretical capacity as a loading guarantee.
- Ignoring payload weight.
- Assuming every container has identical internal dimensions.
