How many boxes fit in your container?
Enter your box dimensions and pick a container or pallet. The calculator finds the best orientation and tells you how many boxes will fit by volume and by stacking.

A few things to know
The "boxes that fit" count is the maximum from trying all 6 rotations of your box and stacking it rectangularly in the container. This is sometimes called a palletizing calculation.
The "by volume only" number is what you'd get if you could melt your boxes and pour them in. It's an upper bound — real packing always leaves some empty space, especially when box dimensions don't divide evenly into container dimensions.
For real loading, also consider weight limits (most 20-ft containers max out around 22 tonnes / 48,000 lb), structural support (stack heavy boxes on the bottom), and access (boxes you need first should be loaded last).
Pallets are smaller targets but follow the same logic — try fitting your box at 48×40×height for a GMA pallet, with the maximum stack at 96 inches total.
