For exporters, importers and freight forwarders
Container load planning with 3D stowage
Simulate how many pallets and boxes fit in a 20ft, 40ft, 40ft HC or 40ft reefer, how much the cargo weighs and how best to place it, before you book space with the shipping line.

Book the right container and fill it well
How many pallets and boxes fit
Test the cargo in a 20ft, a 40ft or a High Cube and compare how much volume and payload each one uses.
Weight and center of gravity
Check the total weight against the container payload and avoid loading too much to one side or toward the back.
Real stacking and order
It respects each box’s stacking limit, fragile items and boxes that cannot be rotated, so the plan can actually be executed on the dock.
Foreign-trade documents
Generate the country-specific packing list and the load manifest as PDFs from the same plan.
Dock mode
Open the plan on your phone and guide the stuffing of the container box by box.
Reference containers
Interior dimensions from the CubiPacks base catalog. They are good for a first estimate; the final booking is confirmed with the shipping line.
| Container | Length | Width | Height | Payload |
|---|---|---|---|---|
| 20ft Dry Standard (20ft ST) | 5.90 m | 2.35 m | 2.39 m | 28,200 kg |
| 40ft Dry Standard (40ft ST) | 12.03 m | 2.35 m | 2.39 m | 26,700 kg |
| 40ft High Cube (40ft HC) | 12.03 m | 2.35 m | 2.70 m | 26,580 kg |
| 40ft Reefer High Cube | 11.58 m | 2.29 m | 2.55 m | 29,520 kg |
Reference values: they vary by manufacturer, shipping line and the tare of each unit. In a reefer, leave room for cold-air circulation.

Container loading: frequently asked questions
How many pallets fit in a 20ft and a 40ft container?
With 1.20 × 1.00 m pallets, a 20ft floor takes about 10 and a 40ft takes 20 to 21. The total also depends on height and permitted stacking, which is why simulating the real cargo is worth it.
What is the difference between a 40ft ST and a 40ft High Cube?
They share the same length and width, but the High Cube is about 30 cm taller inside (close to 2.70 m versus 2.39 m), giving more volume for light or stackable cargo.
Does it work for reefer containers?
Yes. The catalog includes the 40ft Reefer High Cube with its interior dimensions and reference payload.
How do I balance the weight inside the container?
CubiPacks computes the cargo’s center of gravity and shows it next to the total weight against the payload, to avoid a load heavy on one side or toward the back.
Can I get the packing list?
Yes. From the same plan you can generate a PDF packing list with country-specific identification marks, plus the load manifest.
