Container Loading Calculator

Enter the packed size and weight of one unit and the loading plan comes back — units per layer, layers, the volume and payload limits, and which of the two binds first.

How many units fit in the container?

20ft or 40HQ · layers, weight limit and utilisation

This calculator answers the question that decides whether an order is economic: how many flat-pack units or panels load into one container. Enter the packed size of one unit, and it returns the loading plan — units per layer, how many layers fit the height, the volume and weight limits, and which of the two binds first.

It does not estimate. If a dimension or the unit weight is missing it returns a list of what is missing instead of a number, because a guessed loading plan is how deposits get lost.

Loading plan

Container Internal length × width × height and payload are the typical published values; confirm with the carrier.

Packed length of one unit (mm) *

Packed width of one unit (mm) *

Packed height of one unit (mm) *

Weight of one unit (kg) * Without the unit weight the payload limit cannot be checked — this is the number most loading plans get wrong.

Stacking limit (layers) If the factory or the packing method allows only a set number of layers, enter it here.

Allow rotating each unit 90°

Reference only: our own flat-pack container houses load 4 units per 20ft and 8 units per 40HQ. Those are our product figures — the calculator above works for any packed size you enter.

FAQ

Is a 20ft or a 40HQ container better for flat-pack units?

A 40HQ carries roughly twice the volume of a 20ft and relatively less weight per unit of volume, so tall light units suit it best. Enter both container types in the calculator with your packed size and compare the units you can load.

Why does the calculator ask for the unit weight?

Because volume and payload bind differently. A container can be volumetrically full and still be under its payload limit, or the other way round. The calculator reports both and tells you which one limits the load.

What if I do not know the packed height yet?

Then the calculator returns what is missing rather than a number. The packed height is normally confirmed with the factory packing method, and it changes the number of layers more than any other dimension.

Do you confirm the loading plan before booking?

Yes. Send the packed size and unit weight with your enquiry and the loading plan is checked against the actual packing method before the container is booked.
