45ft Palletwide Container Loading Calculator
Test mixed cartons or complete loaded pallets against the 45PWHC profile. Compare floor use and unused quantities before choosing a longer palletwide unit.
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 45ft high cube palletwide is wider than the standard-width 45HC profile. This 45PWHC model has a 1355.6 x 244.4 x 269.4 cm inside envelope, about 89.255 m3. Test your actual complete loaded-pallet or carton order; the supplier’s 33-Euro-pallet reference is not a guarantee for every 45ft unit.

Open the 45PWHC 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
The Seaco reference is 33 Euro pallets for this specific variant. Do not automatically double that number: stacking requires suitable complete units, height and weight checks, and an appropriate physical loading assessment.
| Field | CBM3 11.63.55 profile | Seaco product example |
|---|---|---|
| Interior length x width x height (cm) | 1355.6 x 244.4 x 269.4 | 1355.6 x 244.4 x 269.4 |
| Door width x height (cm) | 241.6 x 258.5 | 241.6 x 258.5 |
| Cargo payload (kg) | 29,250 | 29,250 |
| Volume (m3) | 89.255 rectangular envelope | 89.2 published nominal value |
The supplier column refers only to the Seaco 45ft High Cube Palletwide 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.
Use a valid pattern, not sixteen pairs plus one
Sixteen paired 80 cm-long rows occupy 1,280 cm. The remaining 75.6 cm in this profile cannot accommodate an additional 80 cm-long footprint. A different geometric pattern, eleven rows of three 80 cm-wide by 120 cm-long footprints, uses 1,320 cm by 240 cm and accounts for 33 units. Neither drawing establishes handling clearance or a securing method.
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 | 33 | 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 | 33 | 33 | 0 | 1 | 38.016 | 13,200 |
| B | Best Balance | 33 | 33 | 0 | 1 | 38.016 | 13,200 |
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.

Read the 33-Position Footprint Reference Correctly
For 80 x 120 cm bases, three 80 cm sides across require 240 cm and eleven 120 cm-long rows require 1,320 cm. Against this envelope that leaves 4.4 cm across and 35.6 cm along the length. These are simple pattern residuals, not approved forklift, cargo-wrapping or restraint allowances. Real outside load dimensions can consume them.
The entered 33 complete floor units total 80 x 120 x 120 x 33 / 1,000,000 = 38.016 m3 and 33 x 400 = 13,200 kg. Their base height and tare are already included. No stacking or side-tipping permission is assumed. Cargo-envelope CBM and known unit mass exclude unentered materials and are not a VGM declaration.
45ft Palletwide Loading Questions
Does any 45ft high cube hold 33 Euro pallets?
No. A supplier count depends on a particular wider model and reference base sizes. Do not apply it to the standard-width 45HC or another SeaPC+ variant. Confirm the actual equipment and test the complete outside envelopes.
What if shrink wrap or goods overhang the pallet?
Measure the widest loaded footprint instead of entering only the empty base. Preserve total height and gross unit mass. The recorded example does not include overhang, protective boards or additional working clearances.
Can I stack two loaded pallets in this high cube?
A taller container does not make the unit stackable. Enable stacking only when the complete load and its permitted supported mass allow it, while respecting height, support and doorway constraints. The floor-unit example explicitly disables stacking.
Why can a load be smaller than the container CBM but still fail?
A total volume does not describe footprint, orientation or access. Keep each different package or pallet size in its own row and review the per-container allocation. Weight, support and upright permissions may also prevent an arrangement despite unused volume.
Should I compare this with 40PWHC or 45HC?
Use the same cargo inputs and handling rules for each equipment profile you are actually considering. Compare placed/unplaced quantities and container allocation, then confirm route and supplied-equipment suitability. More nominal volume is not a guaranteed reduction in containers or freight cost.
References and Check Dates
Named equipment reference: Seaco, 45ft High Cube Palletwide, metric specification and pallet table rechecked 7 October 2026. The current profile is CBM3 11.63.55, checked for unchanged-source/profile compatibility on 7 October. Engine examples retain the original 6 October 11.63.52 test date. IMO/ILO/UNECE CTU Code is the named guidance reference, not approval of this cargo arrangement.
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.
