The calculator combines physical dimensions, pallet layout and payload limits. These result fields explain why a load fits — or why adding one more package, pallet or unit is no longer possible.
Units are the individual products, packages are the cartons or cases that contain them, and pallets are the loaded pallet bases used for handling. The result shows the maximum practical count at each level from the dimensions and weights you entered.
This is the percentage of the container's internal cubic volume occupied by the calculated load. A high volume percentage does not by itself guarantee that more cargo can fit: floor layout, height, orientation or payload can become the real constraint first.
This compares the estimated loaded cargo weight with the container's maximum payload. Dense cargo can reach the payload limit while significant physical space is still empty, so weight and volume always need to be checked together.
The limiting factor is the first constraint that prevents another unit, package or pallet from being loaded. Depending on the scenario, it may be payload, floor space, internal height, pallet capacity or the geometry of the available space.
Orientation describes how the package or pallet is rotated inside the available space. The calculator tests the allowed orientations and uses the arrangement that gives the best valid fit. Side placement is considered only when you explicitly allow it.
The three standard options differ mainly in internal length, height and payload. Actual specifications can vary slightly by container and carrier, so confirm the final booking against the container plate or carrier specification.
Approx. internal size: 5.89 × 2.35 × 2.39 m. Payload used by the calculator: 28,180 kg. A good choice for smaller or dense shipments where the higher payload-to-volume ratio is useful.
Approx. internal size: 12.03 × 2.35 × 2.39 m. Payload used by the calculator: 26,580 kg. It provides roughly twice the floor length of a 20 FT container, but not twice the payload.
Approx. internal size: 12.03 × 2.35 × 2.69 m. Payload used by the calculator: 26,330 kg. It has the same floor footprint as a standard 40 FT but about 30 cm more internal height, which helps with taller cargo and additional stacking.

It's a mathematical estimate based on the dimensions and weights you enter. Always confirm the final loading plan with your carrier — real loading also depends on weight distribution, packaging, and transport safety rules.
No. Product, package and pallet values you type are used only to run the calculation and are never saved to a database.
20 ft, 40 ft, and 40 ft High Cube, with standard internal dimensions and payload limits.
It tells you which constraint capped your load — weight, volume, floor space, stack height, or the carrier's pallet limit — so you know what to optimize first.
Up to 11 Euro-pallets (120×80cm) using an optimized mixed-orientation floor layout, or around 9-10 standard/GMA pallets — the exact number depends on your pallet size and load height. Use the calculator above for your specific dimensions.
Up to 25 Euro-pallets in a single floor layer, or around 20-21 standard/GMA pallets — this matches the industry-standard figures freight forwarders use. A 40ft High Cube has the same floor capacity, just more stacking height.
CBM is length × width × height of your cargo (in meters), multiplied by the quantity. Our calculator computes this automatically and shows it alongside volumetric and chargeable weight once you run a calculation.
Volumetric (dimensional) weight estimates how much space your cargo takes up, converted to an equivalent weight. Chargeable weight is whichever is higher — actual weight or volumetric weight — and it's what carriers typically bill on. Both are calculated automatically in your results.
Same floor footprint (1203×235 cm internally), but the High Cube is about 30cm taller (269cm vs 239cm internal height) — useful for taller cargo or extra stacking, not for fitting more pallets on the floor.
Yes — switch to "How much do I need?" mode, enter your total quantity of units or packages, and the calculator works out how many pallets and containers you'll need, including how full the last (partial) container would be.
Payload is the maximum cargo weight the container is designed to carry, excluding the container's own tare weight. A load can run out of payload before it runs out of physical space, especially with dense cargo. Always confirm the exact payload on the real container or carrier specification before shipping.
Pallets add their own footprint, height and empty weight, and they constrain cartons to a palletized layout. The calculator therefore checks pallet dimensions, pallet load height, pallet weight limits and the number of loaded pallets that can physically fit inside the container.
Yes. Use Multiple Products mode to enter more than one product or package type. The calculator combines the rows into one loading scenario and estimates how the different products share the available container capacity.
Yes. Choose Custom to enter the container's internal length, width and height. Max payload is optional: leave it blank to calculate without a container weight limit. Your last custom dimensions are saved only in this browser, and Custom is available for manual calculations but is never included in Recommended container comparisons.
Rotating a package can change how efficiently rows, columns and layers use the available space. The calculator evaluates the orientations allowed by your settings and selects a valid arrangement; placing a package on its side is never assumed unless you enable that option.
