Plan your container load

A top view and a side view of the first container, with each cargo type loaded in rows along its length. It shows the arrangement behind the box counts so you can sanity-check the plan. It is a planning drawing, not a certified stuffing plan.

Space utilization is the total volume of your fitted cargo divided by the container's internal volume, shown as a percentage. It reflects how much of the container's cubic capacity your shipment uses.

Cargo fit depends on shape as well as volume. Boxes that don't divide evenly into the container's length, width, or height leave unusable gaps, this is normal in real container loading and is why the calculator reports a maximum fit per orientation rather than raw volume division.

Yes. Add as many cargo line items as you need. The calculator allocates container space across all item types proportionally, then checks the combined weight against the container's payload limit.

The calculator will cap the fitted quantity so total weight stays within the container's maximum payload, even if there's still volume available. Weight becoming the limiting factor before volume is common with dense cargo like metal parts, machinery, or fertilizer.

Each unit takes a share of a container's space and of its weight allowance, and a container is full when either runs out. The calculator fills containers one after another, never splits a single item, and reports the total for the container type you chose and for every other size. For example, cargo that needs 2.4 containers' worth of space needs 3 containers.

Yes. Choose centimeters, meters, inches or feet for dimensions and kilograms or pounds for weight. Switching units converts the values you have already typed, and the results show cubic feet and pounds when you work in imperial units.

'This side up' stops the calculator from tipping a box onto its side, so its height stays vertical (it can still turn on the floor). 'Do not stack' loads that item in a single layer. Both reduce how much fits, which is how the real cargo behaves.

If your cargo doesn't fully fit, compare containers in the results below. A larger container reduces per-unit shipping cost if you can fill it; splitting across two smaller containers can be cheaper if a single larger container would still be significantly under-utilized.
