Plan your 40ft high cube container with the actual dimensions of your cargo. See how cartons stack, what gets loaded and what remains outside the plan.
A practical guide with inspectable inputs and a calculated example.A 40ft high cube gives you more height than a standard 40ft container. The number of cartons it can carry still depends on each carton’s dimensions, permitted orientation, stacking limits and weight. Start with a packlist, then inspect a calculated arrangement.
These are CargoSNX planning preset values. Compare them with the container you will actually use.
Both names are commonly used for a 40ft high cube container. Choose the 40-foot High Cube preset in CargoSNX and check its internal dimensions, door opening and payload against the equipment for your booking. A dry high cube is different from a refrigerated container; insulation changes the usable space.
Take a carton that must stay upright and is 650 mm high. In the presets used below, three layers fit inside a standard 40ft container and four fit inside a 40HC: 4 × 650 = 2,600 mm. That extra layer is useful only if the carton can carry the load above it and the rest of the arrangement also fits.
The container’s door opening is lower than its internal ceiling. A tall crate can fit the internal dimensions and still fail the opening check. Enter the crate with its packed dimensions, retain its permitted orientations and check the actual door. The planner’s opening check does not simulate forklift access or the full physical loading path.
Review the 3D arrangement, the remaining-item list and the loaded weight together. Empty volume may sit above a non-stackable piece or between incompatible carton sizes. Changing quantities or stacking permissions changes the problem; calculate again after every change.
The high cube result below uses exactly the same mixed shipment as the two standard containers. Compare the pieces placed in one container, then open the example to inspect their arrangement.
| Package | L × W × H (mm) | Quantity | kg / piece | Total m³ |
|---|---|---|---|---|
| Large cartons | 1,000 × 750 × 650 | 80 | 18 | 39 |
| Medium cartons | 800 × 600 × 650 | 40 | 13 | 12.48 |
| Small cartons | 600 × 400 × 650 | 30 | 9 | 4.68 |
| Shipment total | 2,230 kg | 150 | — | 56.16 |
| Container preset | Inside L × W × H (mm) | Placed | Remaining | Volume use |
|---|---|---|---|---|
| 20ft standard | 5,898 × 2,352 × 2,393 | 51 | 99 | 74.9% |
| 40ft standard | 12,032 × 2,352 × 2,393 | 128 | 22 | 76.5% |
| 40ft high cube | 12,032 × 2,352 × 2,697 | 150 | 0 | 73.6% |
More volume use does not mean more of the order loaded. The standard 40ft uses a larger percentage of its interior in this example, but the high cube places all 150 cartons. Read the placed and remaining counts together with the volume percentage.
Preview the example, then choose to load it in the planner.

The tables use the CargoSNX container presets. Equipment varies by manufacturer and unit: Hapag-Lloyd’s container specifications describe that variability, and its 40ft high cube reference provides a carrier example. Check the booked container’s internal dimensions, door opening and payload before using a plan.
This example uses rectangular packages and the stated handling rules. It does not simulate cargo securing, packaging strength, equipment access or the full physical loading path, and it does not prove that the calculated arrangement is optimal. Include the relevant operational checks before loading.
For dry-container planning, both terms commonly refer to a 40ft high cube. Confirm the equipment type and dimensions with your carrier; the abbreviation does not specify every detail of the unit you receive.
The CargoSNX preset has roughly 76.3 m³ of internal geometric volume. That is an empty rectangular volume, not a promise that 76.3 m³ of packaged goods will fit. Door dimensions, carton geometry and stacking rules reduce usable capacity.
Yes. Add a separate row for each package size and handling rule. Give each row its quantity and weight per piece, then calculate and review the items the planner leaves unplaced.
No. More internal height does not guarantee more payload. In the presets shown here, the 40HC payload is slightly lower than the standard 40ft preset. Use the actual unit’s limits and the applicable transport constraints.
