How many pallets fit in a 20ft and 40ft container? (2026 guide)

A 20ft container fits 10–11 Euro pallets or 9–10 GMA pallets in a single floor layer; a 40ft fits 20–24 Euro pallets, and a 40ft High Cube up to 25. The exact number depends on your loading pattern, not just your container and pallet size, which is why published figures for “pallets per container” vary across the industry, and why both the higher and lower numbers you’ll find are usually correct, just for different loading arrangements.

This guide gives you the real ranges for Euro pallets, GMA (standard American) pallets, and double-stacking scenarios across 20ft, 40ft, and 40ft High Cube containers, along with why the range exists and how to get a precise number for your specific shipment.

Quick answer

Ranges reflect single-layer floor loading. The lower end of each range is a simple grid layout; the higher end reflects optimised block-stow or pinwheel arrangements. Double-stacking adds to these figures far less often than most sources suggest, for reasons covered in the double-stacking section below. For the internal dimensions behind these figures, see our guide to shipping container dimensions.

Why the numbers vary: loading pattern matters more than container size

Two operations can use the same container and the same pallets and still fit a different number, because the loading pattern determines how much of the container’s width and length is actually used.

A simple grid layout (pallets placed in straight rows with consistent spacing) is the easiest to plan but wastes space near the container walls and doors. An optimised block-stow or pinwheel arrangement rotates some pallets and tightens spacing to use almost the entire floor area, typically adding 2 to 4 more pallets per container compared to a simple grid.

This is also why two reputable sources can both be correct while quoting different numbers: “10 Euro pallets” and “11 Euro pallets” in a 20ft container are both real, achievable figures depending on how carefully the load is arranged.

Euro pallets vs GMA pallets

The Euro pallet (1200 × 800mm) is the international standard, especially across Europe and in most cross-border ocean freight. The GMA pallet (48 × 40 inches, or 1219 × 1016mm), sometimes called the standard American pallet, is the North American standard, common in retail, grocery, and food distribution.

Because the Euro pallet has a narrower footprint, more of them typically fit in the same container space compared to GMA pallets, even though the difference in any single dimension looks small on paper.

Double-stacking: the three constraints that decide it

Double-stacking adds capacity far less often than published figures suggest, and when it does work it rarely doubles the count. Three separate constraints have to clear at once, and in a 40ft container the one that usually fails is weight, not height.

Can the bottom tier carry the top one?

The pallet itself is almost never the limit. A standard EPAL 1 Euro pallet is rated to carry around 1,500kg, comfortably more than a second loaded pallet weighs in most shipments. What fails is the goods underneath: cartons, sacks, drums and anything with void space above it will crush, deform or shift long before the pallet does. If the bottom tier is not a solid, evenly loaded block with a flat top surface, it is not a double-stacking candidate regardless of what the numbers say.

Does the payload limit allow it?

This is the constraint most guides skip, and it is usually the binding one. A 40ft Standard container has a payload limit of about 26,580kg. Doubling 20 floor pallets to 40 means each loaded pallet has to average under roughly 660kg or the container is overweight before it leaves the yard. That rules out most palletised food, drink, tinned goods, tiles, paper and hardware immediately.

A 20ft container is the more forgiving case, which is the opposite of what most people assume. Its payload limit is about 28,080kg spread across only 10 floor pallets, so doubling to 20 still allows roughly 1,400kg per loaded pallet. Dense cargo in a 20ft container is often weight-limited before it is volume-limited, which means the floor is already carrying all the mass it can and the space above it stays empty whatever you do.

Does each tier fit under the roof?

Two tiers have to share the container’s interior height, and each tier spends part of its allowance on the pallet itself. In a 239cm standard container, two 14.4cm pallet bases leave about 210cm of goods across both tiers, so each loaded tier has to come in under roughly 119cm including its pallet. In a 269cm High Cube that rises to about 134cm per tier. Most loaded pallets are taller than 119cm, which is the honest reason double-stacking in a standard container is frequently not possible at all.

Put the three together and the realistic answer for a lot of shipments is that double-stacking adds nothing. That is not a failure of planning, it is what the constraints produce, and it is better established before the booking than discovered at the dock.

Maximum pallet and cargo stacking height

The maximum cargo height on a standard pallet is about 224cm (88 inches) in a 20ft or 40ft container, and about 254cm (100 inches) in a 40ft High Cube. Those come straight from the interior heights, less the height of the pallet the goods sit on.

Assumes a standard pallet base of roughly 14.4cm (the EPAL 1 height). Figures include the pallet, so subtract the pallet height again if you are measuring only the goods.

Why published maximum heights contradict each other

Search for a maximum pallet height and you will find 72 inches, 89 inches and 90 inches quoted with equal confidence. All three are correct, because they are answers to three different questions that get asked with the same words.

Roughly 72 inches is a carrier or warehouse handling convention. It has nothing to do with containers; it comes from what a person or a machine can safely wrap, move and put away, and it is the number a warehouse manual is most likely to quote. Roughly 88 to 90 inches is close to the physical ceiling inside a standard container. Roughly 100 inches is the physical ceiling inside a High Cube.

There is also a fourth constraint nobody publishes, because it is specific to you: the receiving warehouse at the other end may cap pallet height lower than any of the above, and will refuse the delivery if you exceed it. The height that governs your shipment is whichever of those four is lowest, so check the destination’s receiving rules before planning to the container ceiling.

Pallet types: Euro, GMA, ISO, CHEP, block and stringer

Pallet capacity questions almost always come down to footprint, and there are only a handful of footprints in common international use. The table below covers the ones you will actually meet in containerised freight.

CHEP is a pooling operator rather than a size standard: it rents pallets in several of these footprints. Its European standard is the 1200 × 1000mm industrial pallet, and its 1165mm square Australian pallet is the one genuine outlier, since it does not divide neatly into a 235cm container width the way the 1200mm sizes do.

Block versus stringer construction

Block pallets are supported by nine solid blocks, leaving openings on all four sides so a forklift can enter from any direction. Stringer pallets are built on two or three long parallel boards and normally accept forks from two sides only, though notched stringers allow partial four-way entry for a pallet truck.

Inside a container this matters more than it sounds. Four-way entry lets you rotate pallets to suit the loading pattern, which is exactly what the block-stow and pinwheel arrangements above depend on to gain their extra two to four pallets. With two-way stringer pallets, the orientation is chosen for you by where the forklift can reach, and the optimised layouts may simply not be loadable. Euro and CHEP pallets are block pallets; the North American GMA pallet is most commonly a stringer pallet.

These ranges are useful for early planning, but they are generic: they don’t know your exact pallet dimensions, your cargo height, or whether your goods can be double-stacked. For a precise answer, use our free container loading calculator. Enter your exact pallet or carton dimensions and quantity, and it calculates real space utilisation for your specific shipment, not a published industry range. For a quick volume-only check, our CBM calculator gives your total CBM in seconds.

Shipping by road rather than by sea? The same layout logic applies to different dimensions, and the numbers change: see how many pallets fit on a 48ft and 53ft trailer. If the load is dense enough that weight becomes the binding constraint, our truck axle load calculator checks whether the positions you have in mind are legal.
