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.
Cartons must individually pass the door in their final orientation. They are stacked inside; the complete stack need not pass the door.
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.
