Frequently Asked Questions

Internal dimensions represent the actual usable space inside a container, while external dimensions include the wall and door thickness. Our calculator requires internal dimensions because that's what your cargo can occupy.

Yes, you can enter any number of items, even if they don't fill the entire container. The tool will show you how much space your cargo takes and the remaining empty volume.

Currently, the free version focuses on volume optimization. If your cargo is very dense, you should manually verify that the packed items do not exceed the container's weight capacity. A weight-constraint feature is on our development roadmap.

The 3D view uses WebGL and adapts to your screen size. On smartphones, the preview appears below the form. You can rotate and zoom using touch gestures.

No. We send your input to our server for the calculation, but we do not log, store, or share any of your shipment details.

At the moment, embedding is not supported, but we plan to offer a white-label version and a REST API for businesses. Contact us if you're interested.

Real-world packing always has some unusable space. Our algorithm prioritizes quick, practical solutions that are usable in real logistics operations rather than theoretical 100% fill rates.

The free version supports up to 500 items of varying sizes. For larger calculations, we recommend grouping similar items to reduce the row count.

The plan is mathematically accurate for rectangular items. In practice, minor deviations may occur due to packaging deformations or human loading methods. Always treat the output as a highly reliable guide.

We are developing a REST API that will allow you to integrate our calculation engine directly into your own systems. If you need API access, please reach out with your requirements.
