Container Loading Calculator

Free packing calculator for shipping containers and export cartons. Define the outer container or carton dimensions (or pick a standard container), then list up to 10 products with their length, width, height, weight and quantity. The tool calculates exactly how many products fit, the total product volume, total weight, remaining space, and visualizes the packing plan in an interactive 3D scene with a PDF report export.

Frequently Asked Questions

How does the tool decide how many products fit?

It uses rectangular bin packing. For each product it calculates how many whole items fit along the length, width and height axes of the outer box, and validates the arrangement against the available container volume so the plan is achievable.

Can I use a standard shipping container size?

Yes. The tool offers both a carton and a container mode. In container mode you can model a standard shipping container (ISO 668 dimensions) or enter any custom inner dimensions that match your actual box.

What units are supported?

Dimensions are entered in inches with a cm secondary field that converts automatically. Volumes are reported in in³ and ft³, and weights in lb, matching US shipping documentation conventions.

Can I export the packing plan?

Yes. After calculation you can export a professional PDF report that includes the outer box info, product list, loaded quantities, total volumes and total weight, ready for shipping documentation.
