45ft High Cube Container Loading Calculator
Test a shipment in the 45HC profile. The longer floor and high-cube height help only when your package sizes, stacking permissions and cargo weight allow them to be used.
Test the quantity you enter and review placed and unplaced cargo. This is a planning estimate, not a maximum-capacity guarantee or transport approval.
A standard-width 45ft high cube is not a 45ft palletwide container. For this CBM3 45HC planning profile, the rectangular inside envelope is 1355 x 235 x 270 cm, about 85.975 m3. Test your actual carton or complete loaded-pallet quantities below; dividing that volume by box volume is not a physical-fit calculation.

Open the 45HC loading planner. Start with a new job and confirm the selected equipment. This is an initial selection, not an automatic calculation; a saved job or your own equipment choice takes priority.
Planning profile and an equipment supplier example
CBM3 uses rounded interior dimensions and a 27,600 kg planning limit. The Seaco equipment example below differs. The profile does not supply a door opening, tare or maximum gross mass; do not turn an absent value into a passed check.
| Field | CBM3 11.63.55 profile | Seaco product example |
|---|---|---|
| Interior length x width x height (cm) | 1355 x 235 x 270 | 1355.6 x 235.2 x 269.8 |
| Door width x height (cm) | Not supplied | 234 x 258.5 |
| Cargo payload (kg) | 27,600 | 27,800 |
| Volume (m3) | 85.975 rectangular envelope | 86 published nominal value |
The supplier column refers only to the Seaco 45ft High Cube Dry Freight specification. Seaco supplies and leases containers; this is a fleet specification, not a manufacturing certificate. Confirm the equipment actually supplied. Interior volume is not a cargo-fit result; a listed door size is not a simulated loading path.
Do not substitute palletwide dimensions
The CBM3 45HC profile is 235 cm wide. Two 120 cm-wide floor units would need 240 cm, so that particular paired row cannot fit. Horizontal rotations and mixed rows can produce different arrangements; a failed pattern is not proof that the complete order cannot fit.
Reproduce two entered-order examples
Use metric units with palletization off. Keep rotation at Horizontal Only and leave global rules off. Normal loading priority, no delivery stop, no fragile marking and no additional maximum stack-weight limit are used. These are synthetic examples, not measured customer shipments.
| Example | Width x length x height (cm) | Quantity | kg per complete unit | Stackable | This Side Up |
|---|---|---|---|---|---|
| A: cartons | 40 x 60 x 80 | 40 | 25 | Yes | No |
| B: complete floor units | 80 x 120 x 120 | 24 | 400 | No | Yes |
Example B treats each already assembled unit as one box-shaped outer envelope. Its 120 cm height and 400 kg mass already include its base and contents. Do not add pallet height or tare again. This test is manual outer-envelope entry, not evidence of the separate pallet-transfer workflow. Full 3D Rotation and stacking are not permitted for these units.
| Example | Method | Entered | Placed | Unplaced | Containers | Cargo envelope m3 | Known unit mass kg |
|---|---|---|---|---|---|---|---|
| A | Max Volume | 40 | 40 | 0 | 1 | 7.680 | 1,000 |
| A | Best Balance | 40 | 40 | 0 | 1 | 7.680 | 1,000 |
| B | Max Volume | 24 | 24 | 0 | 1 | 27.648 | 9,600 |
| B | Best Balance | 24 | 24 | 0 | 1 | 27.648 | 9,600 |
Engine verification used the installed 11.63.52 Worker in Node, with independent quantity, orientation, boundary, overlap, support and payload checks. It is not a real-browser demonstration, a physical-loading test or a proof of maximum capacity. A different load, restriction or unit can produce a different result.
Review before organizing the physical load
- Measure the complete outer packages, including overhang and wrapping, and confirm the real equipment.
- Check the entered, placed and unplaced quantities for every container. Review the actual order and its handling permissions, not a reference pallet count.
- Assess access, load distribution, stacking suitability and securing with the responsible loading team. The known unit mass in the example excludes the container and any unentered materials; it is not VGM.
The IMO/ILO/UNECE CTU Code is voluntary global packing guidance. A geometric result is not transport approval. Securing choices and applicable requirements need a separate assessment.

Check 45ft Cargo CBM, Height and Known Weight
For packed box dimensions in centimetres, cargo CBM is width x length x height x quantity / 1,000,000. The 40-carton example is 40 x 60 x 80 x 40 / 1,000,000 = 7.680 m3. Its known mass is 40 x 25 = 1,000 kg. Keep different packed sizes in separate rows rather than replacing a mixed order with an average carton.
A higher ceiling does not permit a taller package to pass through a lower doorway. This preset has no verified door opening: a rendered unit inside the container is not a passed door check. Use the assigned unit’s real door and inside measurements, upright handling requirements and working clearance. The 27,600 kg software cargo limit is not container gross mass or a road/rail route authorization.
45ft High Cube Loading Questions
How many boxes fit in a 45ft high cube?
There is no single count without a packed size, quantity and handling rules. The recorded example places the entered 40 cartons; it does not search for an unrestricted maximum. Run your order and reconcile placed and unplaced quantities per container.
Does a standard 45ft high cube hold 33 Euro pallets?
Do not transfer a palletwide reference count to this narrower profile. The 235 cm software width cannot contain a 240 cm paired row. Other horizontal patterns may work, but a failed row pattern neither proves an optimum nor establishes that the whole order fails.
Can I turn a loaded pallet onto its side to fit?
Keep a complete loaded pallet upright, permit only horizontal turning and leave stacking off unless the unit is explicitly stackable. Enter its full outside height and gross unit mass once, including the base. The complete-floor-unit example follows those permissions; it is not a pallet-building demonstration.
What is the difference between 45HC and 40HC?
Compare the actual equipment profiles for inside length, width, height, payload and doorway information. A nominally longer container may help with an entered order, but more rectangular volume alone does not prove fewer containers. Use the same cargo and rules when comparing results.
Is the 3D plan a transport-safety approval?
No. It is an arrangement under the entered rules and available profile data. Packaging strength, access, securing and applicable transport requirements need separate review. Container tare and securing materials are not automatically included in the entered cargo mass.
References and Check Dates
Named equipment reference: Seaco, 45ft High Cube Dry Freight, metric specification rechecked 7 October 2026. The current planning profile is CBM3 11.63.55; the unchanged-source compatibility check is dated 7 October. The recorded engine examples retain their original 6 October 11.63.52 test date. IMO/ILO/UNECE CTU Code is the named packing-guidance reference, not certification of this simulated order.
Software compatibility note, 8 October 2026 (Europe/Istanbul): The planning profiles and recorded example inputs were checked against the source-reviewed CBM3 11.63.56 candidate. The earlier example execution dates remain unchanged; this compatibility review is not a new optimization run or physical-loading test. Fleet-provider and carrier references are not manufacturer approval. Confirm the actual unit dimensions, payload and securing requirements.
How to inspect and hand over a loading plan
Use the selected plan and the complete shipment data. Recheck the result after changing cargo, equipment or handling rules.
See every cargo unit in context
Search the cargo inventory, focus on an item and switch between realistic, operational, top and side views. Inspect pallet layers and height sections.
The inventory separates requested units, units in the selected container, units in other containers and unplaced units. Select a row to find its cargo in the scene; playback and height sections show only part of the complete plan.
Use pallet details to inspect full, partial and mixed pallets. A height section filters the view; it does not remove cargo from the plan. Vehicle bodies and wheels provide visual context.
Prepare clearer warehouse instructions
Use product colors and short codes, named groups and delivery stops. Choose a summary or warehouse PDF for the selected plan.
Assign product colors and short codes to connect the cargo table, 3D view and reports. Group and stop names improve instructions; apply the appropriate loading rules when a sequence must be enforced.
Compare verified alternatives and review any manual moves. A manual reallocation affects the current preview and PDF; saved or shared inputs recalculate the automatic arrangement when reopened. Export again after changes.
Read the estimated center of gravity
Review longitudinal, lateral and height coordinates from known cargo and pallet masses. Check the displayed origin and units before comparing plans.
The estimate assumes each item's mass is centered and excludes vehicle tare. Missing or stale additional-material records can leave the complete-load assessment unavailable; explicitly declare none when no extra materials are present.
Coordinates use the load-space frame, not road height. For Step Deck, X starts at the raised front end and Y at the lower-deck datum; axle-form distances run from the rear toward the cab.
Distinguish the loading unit from its carrying vehicle
This loading unit alone does not define an axle configuration.
Inspect cargo and pallet weight distribution in this loading space. A container, swap body or air-cargo unit does not identify the road chassis, rail wagon or aircraft carrying it.
Axle estimates are available after selecting a supported complete road or rail vehicle. Enter its actual mounting positions, full empty reactions and applicable limits; do not reuse a trailer reference as container or aircraft approval.
