Container Loading Calculator for Pallets and Cartons
Estimate how your packed pallets and cartons could be arranged inside a shipping container. Enter the dimensions, quantities and gross weights to generate an indicative floor layout and see which units remain unplaced.
Quick Overview
This container loading calculator plans rectangular pallets and cartons in one floor layer. It considers the selected equipment dimensions, permitted horizontal rotation and the weight limit entered for the calculation.
The result is a planning estimate. It does not confirm a safe loading sequence, weight distribution, cargo securing or carrier acceptance, and it does not calculate freight rates.
Plan Your Container Layout
Container Loading Calculator
Plan rectangular pallets and cartons in one floor layer. All dimensions must include packaging, pallets and overhang. This tool estimates an arrangement, not freight rates.
Indicative Loading Result
Floor Layout — View from Above
Positions are measured from the closed end and one side wall. The door is on the right. Colours identify cargo groups; hover over a unit for its dimensions and position.
| Group | Entered | Placed | Unplaced | Unplaced reason |

Placed-Unit Positions
All coordinates and layout dimensions below are in centimetres. These are planning positions, not a loading sequence.
| Unit | X from closed end | Y from side wall | Length | Width | 90° turn |

Confirm weight distribution, concentrated and floor loads, access, blocking, bracing and lashing separately. The tool does not validate cargo strength, axle loads, dangerous-goods compatibility or verified gross mass.

Enter your cargo details
| Field | What to enter |
|---|---|
| Container | Select a 20ft standard, 40ft standard or 40ft High Cube reference profile. Check the displayed internal dimensions, door opening and weight assumptions against the equipment planned for your shipment. |
| Length, width and height | Enter the external dimensions of the packed unit, including its pallet, wrapping and any overhang. |
| Quantity | Enter the number of identical units. Add a separate row for each different size or gross weight. |
| Gross weight per unit | Include the goods, pallet and packaging. Use the same weight unit throughout. |
| Horizontal rotation | Allow a 90° turn only if the unit may change direction while remaining upright. This does not allow tipping it onto another face. |
| Stackability | Record whether other cargo may be placed on the unit. The floor layout keeps every unit in a single layer, even when it is marked stackable. |

Read your results
| Result | What it means |
|---|---|
| Units placed | Units included in the layout generated with your selected settings. |
| Unplaced units | Units not included in that layout. Review the stated dimensional or weight restriction; some may remain unplaced because of the arrangement found. |
| Floor layout | An indicative view from above showing unit positions and orientation. |
| Cargo volume | The combined packed volume, shown in cubic metres. |
| Gross cargo weight | The combined gross weight of the entered units, with the weight of placed units shown separately. |
| Assumptions and checks | The equipment profile, single-layer rule, rotation settings and weight limit used. |
Text beside the results: This is an indicative layout, not an approved loading or securing plan. Unplaced units do not necessarily mean that no alternative arrangement is possible. Confirm the actual equipment and loading requirements before booking.
How to Use the Container Loading Calculator
- Choose the equipment. Review its internal dimensions, door opening and weight assumptions.
- Measure each packed unit. Use finished dimensions and gross weights, not product measurements alone.
- Set the handling restrictions. Confirm permitted rotation and record stackability.
- Calculate and review. Check the layout, unplaced units and warnings before comparing another container or packing arrangement.
A unit that fits inside the container may still require a separate check for passage through the door and safe handling.
Why CBM Alone Cannot Confirm Container Fit
Two shipments with the same volume can need different arrangements. Pallet footprints, carton shapes, door clearance and permitted orientation affect how the cargo can be placed.
For example, 10 packed pallets measuring 1.20 × 0.80 × 1.40 m each have a combined volume of 13.44 m³. At 450 kg per pallet, their combined gross weight is 4,500 kg. Those totals describe the shipment; they do not establish a suitable loading plan.
Use the CBM calculator when you only need cargo volume. Use this tool when you also want to explore an indicative floor arrangement.
Compare Container Options
A 40ft container offers more floor length than a 20ft container. A 40ft High Cube mainly adds height compared with a standard 40ft container; it does not automatically add pallet positions in a single floor layer.
Review the reference dimensions for a 20ft container, 40ft container or 40ft High Cube container. Actual specifications vary by equipment.
For typical pallet counts and common formats, read how many pallets fit in a container.
Check the Loading Requirements
Before finalising the shipment, confirm weight distribution, concentrated loads, floor limits, handling access, blocking, bracing and lashing. Record any additional securing-material weight separately.
The calculator does not validate double-stacking, package strength, axle loads, dangerous-goods compatibility or the verified gross mass of the packed container. Oversized, irregular or specialist cargo needs a separate equipment and loading review.
