Procedure
How to use this tool
- 01
Choose a representative dry container size.
- 02
Enter one carton’s outside dimensions, weight, and planned quantity.
- 03
Review dimensional capacity, payload-limited capacity, fit status, and utilization.
Useful for
Common planning tasks
- Rough FCL load planning
- Carton-size comparisons
- Spotting payload-bound dense cargo
Model boundary
Assumptions
- Cartons are identical rectangular boxes arranged in one uniform axis-aligned orientation.
- Preset dimensions and payloads are representative planning values, not equipment guarantees.
- Cargo is evenly distributed and packaging tare is included in carton weight.
Operational caution
Limitations
- Door opening, dunnage, clearance, bracing, axle/road limits, weight distribution, and loading sequence are excluded.
- Actual container specifications vary by owner, manufacturer, age, and jurisdiction.
Reference
Questions and answers
Why might the result exceed a real load?
Mathematical grids ignore doors, handling clearance, bracing, damaged cartons, and practical loading sequence.
Does the calculator check payload?
Yes, using a representative preset payload, but the container CSC plate and carrier instructions control.
Can cartons rotate?
The estimator checks all six axis-aligned orientations and reports the highest simple grid count.
