Can I use custom container dimensions instead of the preset sizes?

Yes, the calculator allows you to enter custom container length, width, and height in addition to the preset 20 foot, 40 foot, and 40 foot high cube options.

What does the 'Allow floor rotation' option do?

Enabling this option allows the calculator to rotate cartons 90 degrees to potentially fit more items within the container's footprint.

How accurate is the capacity ceiling number shown in the results?

The capacity ceiling is a heuristic estimate based on published internal dimensions; actual loading may differ due to equipment variations and physical constraints not modeled by the tool.

Can I embed this calculator on my own website?

Yes, FreightTotals provides a free embed option with an iframe code; the calculator must remain attributed with the FreightTotals branding intact.

About this tool

What Container Loading Calculator does

FreightTotals' Container Loading Calculator determines how many cartons fit inside standard shipping containers by comparing the user's carton dimensions against preset container sizes. The tool outputs a planning result showing the number of cartons that fit, the capacity ceiling, leftover space, and the loaded weight. It includes visual load arrangement planning and options to rotate cartons, copy calculations as text or CSV, or embed the calculator on another site while preserving the FreightTotals attribution. The interface supports multiple container types—20 foot, 40 foot, and 40 foot high cube—and provides side elevations and end views of internal dimensions and door openings for comparison. A heuristic estimate notes that actual equipment varies and reminds users to review door clearance, dunnage, load sequence, securing, balance, and local weight limits.
