The tool compares straight and mixed 90° row patterns in both container directions. It selects the best of those patterns, without guaranteeing the best possible packing. All units stay upright.
Capacity = min(layout × layers, payload ÷ gross kg)Round down capacity; round up the container count.
Loaded pallet height must pass the door. Only a single level of identical pallets is estimated.
The drawing shows the first layer at maximum estimated capacity, with the door at right. Dense layouts show only the first 300 units. Volume use compares that capacity with the full internal geometric volume.
Before you book or load
Which specifications are used?
Presets use Hapag-Lloyd equipment examples. Manufacturers and individual containers vary; confirm the actual internal dimensions, door opening and permitted payload.
This geometric estimate does not assess stability, cargo restraint, weight distribution, carton compression, forklift access or road/vehicle limits. Allow handling space and verify these constraints with your carrier and site procedures. Mixed sizes and irregular cargo are outside this model.
What can I export?
The CSV contains your inputs, the selected container estimate and the four reference comparisons. It is generated locally; the tool does not upload your shipment data.
Worked example
Illustrative inputs and outputs to help you check your own task.
AU pallets in a 20ft example
Inputs
Choose 20′ GP and AU 1165 × 1165 mm; loaded height 1500 mm, gross weight 700 kg, shipment 24 pallets, allowance 0.
Output
10 pallets per container. The shipment needs 3 containers; the last has 4 pallets.
This assumes one level and no overhang beyond the entered footprint.
When weight becomes the limit
Inputs
Keep the 20ft AU example and change gross weight to 3000 kg per loaded pallet.
Output
The example payload permits 9 pallets per container; 24 pallets need 3 containers, with 6 in the last.
Verify the actual unit and transport limits. Available floor positions do not override payload.
