How many boxes fit in a 40ft container?

It depends entirely on the box size. Here are the counts for three common sizes — or skip straight to the calculator with your exact dimensions.

It depends
Box size determines everything
Small box (30×20×15 cm)
~7,500
Medium box (60×40×30 cm)
~938
Large box (80×60×40 cm)
~352
Container volume
67.5 m³

Box counts by size

Box sizeDimensionsPer boxApprox. count
Small30 × 20 × 15 cm0.009 m³~7,500
Medium60 × 40 × 30 cm0.072 m³~938
Large80 × 60 × 40 cm0.192 m³~352
Extra large120 × 80 × 80 cm0.768 m³~87

These counts assume optimal packing with no wasted space. In practice, you'll lose 5-15% of the theoretical maximum due to gaps, irregular stacking, and the need to leave space for loading and unloading.

40ft High Cube12,032 mm2,352 mm2,698 mm76.3 m³

A High Cube container adds about 305 mm of headroom, increasing capacity by roughly 13%. If your boxes stack well, this extra height translates directly into more boxes.

Why the real number is always less

Weight limits. A 40ft container's max payload is ~26,580 kg. Heavy items (books, canned goods, machinery parts) will hit the weight limit long before filling the volume.

Irregular sizes. If you're mixing different box sizes, the packing efficiency drops. This is exactly the problem a 3D packing calculator solves — finding the optimal arrangement for mixed loads.

Access and handling. You may need to leave aisles or organize boxes by delivery stop, which reduces the total count further.
