How Many ISO Pallets Fit in a 20ft Container?
A 20ft container takes 10 ISO pallets on the floor in a single layer, 5 down the length by 2 across. The count uses the 5898 x 2352 mm usable interior with no overhang and no stacking.

The short answer
10 ISO pallets on the floor of a 20ft container, 5 down by 2 across, single tier, no overhang. Floor area used: 87.2%.
The 1100 mm square ISO pallet is the tidiest fit of the four standards in a 20ft: 5 down the 5898 mm length leaves 398 mm at the doors, 2 across leaves 152 mm, and orientation is irrelevant because the pallet is square.
Internal dimensions used
- 20 ft Standard Dry: 5898 x 2352 x 2393 mm usable interior (232 x 93 x 94 in), 28,200 kg payload.
- ISO pallet (Asian 1100 x 1100 mm): 1100 x 1100 mm footprint (43.3 x 43.3 in), 140 mm deck, 1,000 kg dynamic rating.
Usable figures sit a little under nominal to allow for corrugation, posts and the door frame; the count is a plain grid with no overhang.
Long side or short side down the container
A 1100 x 1100 mm pallet has one footprint, so there is no long side to choose. Down the 5898 mm length you fit 5 pallets (398 mm left over at the doors) and across the 2352 mm width 2 (152 mm left over). That is 5 x 2 = 10 on the floor, using 87.2% of the floor area. Turning a square pallet changes nothing: the leftover length is either enough for another full row or it is wasted.
What changes with double stacking
Two tiers need every loaded pallet, deck included, at or under 1196 mm in the 2393 mm interior: goods no higher than 1056 mm on a 140 mm deck. The 1500 mm load preset here (1640 mm with the deck) is one tier only. Under 1056 mm the floor count doubles to 20, if the bottom tier can carry the top.
Weight is worth a check too: 10 pallets at the 1,000 kg dynamic rating comes to 10,000 kg against a 28,200 kg payload, so a second tier at full weight would not clear it.
