Example Data Table
| Container | Internal Size m | Carton Size m | Cartons | Cube m³ | Weight kg |
|---|---|---|---|---|---|
| 20 ft GP | 5.90 × 2.35 × 2.39 | 0.50 × 0.40 × 0.30 | 420 | 25.20 | 5,040 |
| 40 ft GP | 12.03 × 2.35 × 2.39 | 0.60 × 0.40 × 0.35 | 300 | 25.20 | 5,400 |

Formula Used
Container Cube = Length × Width × Height
Usable Cube = Container Cube × Fill Factor × (1 − Aisle Allowance) × (1 − Packaging Loss)
Carton Cube = Cargo Length × Cargo Width × Cargo Height
Total Cargo Cube = Carton Cube × Carton Count
Cube Utilization % = (Total Cargo Cube ÷ Usable Cube) × 100
Payload Utilization % = (Total Cargo Weight ÷ Maximum Payload) × 100
Grid Fit = floor(Container Length ÷ Cargo Length) × floor(Container Width ÷ Cargo Width) × floor(Container Height ÷ Cargo Height)

Frequently Asked Questions
1. What does container cube mean?
Container cube is the internal volume available inside a container. It helps estimate how much boxed or palletized cargo can fit before space runs out.
2. Why is usable cube lower than container cube?
Usable cube removes lost space from aisles, clearance, packaging, and practical loading limits. Real loading plans rarely use every cubic meter perfectly.
3. Why check weight and cube together?
A shipment can fill the space before reaching payload, or exceed payload before filling the space. Both limits must be checked for safe planning.
4. What is the best orientation result?
The tool tests six carton orientations and shows the one with the highest estimated fit count inside the selected container dimensions.
5. Does this replace a load plan?
No. It gives fast planning estimates. Final loading should also consider door clearance, pallet overhang, cargo fragility, weight distribution, and lashing needs.
6. Can I use inches or feet?
Yes. The calculator converts common length units to meters internally, so you can work with inches, feet, millimeters, centimeters, or meters.
7. How do CSV and PDF downloads work?
CSV exports result rows or example data to a spreadsheet-friendly file. PDF uses your browser print dialog to save the visible report.
