How Many Pallets Fit in a 40 ft Container?

Shipping goods internationally means making the most of every cubic foot inside a container. Whether you are a freight forwarder quoting a client, a warehouse manager planning an outbound load, or a small business owner shipping your first full container load, one question comes up repeatedly: how many pallets actually fit in a 40 ft container? The short answer is that a standard 40-foot dry container holds 20 to 22 standard US pallets (48 x 40 inches) in a single layer, while Euro pallets (1200 x 800 mm) can squeeze in 24 to 30 units depending on how they are arranged. But the real answer depends on pallet type, cargo height, weight restrictions, stacking ability, and the loading method you choose.

This guide breaks down the internal dimensions of a 40 ft container, compares the most common pallet sizes, explains the loading configurations that professional logistics teams rely on, and highlights the factors that can make or break your container utilization rate.

Understanding 40 ft Container Dimensions

Before you can calculate pallet capacity, you need to know precisely what you are working with. A standard 40-foot dry container — classified as an ISO 1CC container — has the following approximate internal dimensions:

• Length: 12.03 meters (39 feet 5 inches)
• Width: 2.35 meters (7 feet 8 inches)
• Height: 2.39 meters (7 feet 10 inches)

These numbers give you a total internal volume of roughly 67.5 cubic meters (2,385 cubic feet). However, volume alone does not determine how many pallets you can load. The floor area is what matters for single-layer loading, and that comes out to approximately 28.3 square meters (304 square feet).

One detail that catches inexperienced shippers off guard is the door opening. The rear doors of a standard 40 ft container open to a width of about 2.34 meters and a height of approximately 2.28 meters. That door width is slightly narrower than the internal width, which means pallets loaded sideways need to clear the doorframe before being pushed to their final position.

It is also worth noting the difference between a standard height container and a High Cube (HC) container. A 40 ft High Cube adds roughly 30 centimeters (one foot) of internal height, bringing the ceiling up to about 2.69 meters. The floor dimensions stay the same, so the number of pallets in a single layer does not change, but the extra headroom can be a game-changer for double stacking or for shipping tall goods.

Pallet Types Compared

Not all pallets are created equal, and the type you use has a direct impact on how many units fit in a container.

Standard US Pallet (GMA Pallet)

The Grocery Manufacturers Association (GMA) pallet measures 48 x 40 inches (1219 x 1016 mm). It is by far the most common pallet in North America. When loaded with the 40-inch side facing the container wall, you can fit two pallets side by side across the width of the container, with minimal wasted space. Running ten pairs down the length gives you 20 pallets in a single layer. With careful arrangement, some shippers manage to fit 21 or even 22.

Euro Pallet (EUR1 / EPAL)

The Euro pallet measures 1200 x 800 mm (approximately 47.2 x 31.5 inches). It is the dominant format across Europe and is increasingly used in Asia. The slightly narrower width allows for more creative loading configurations. In a straightforward two-row layout, you can fit 24 to 25 Euro pallets in a single layer. Using a pinwheel or alternating arrangement, experienced loaders can push that number to 28 or even 30.

Industrial Pallet

The industrial pallet measures 48 x 48 inches(1219 x 1219 mm). Its square shape is common in chemical, paint, and hardware industries. The extra width means you lose space across the container's width. Typically, you can load 18 to 19 industrial pallets in a single layer.

Loading Configurations That Maximize Space

How you physically place pallets inside the container matters just as much as which pallet type you use.

Straight Loading (Lengthwise Rows)

This is the simplest and most common method. Pallets are placed in two parallel rows running the length of the container, with the shorter side of each pallet facing the container wall. For standard US pallets, the 40-inch side sits against the wall, and the 48-inch side runs toward the center. Two pallets side by side span roughly 80 inches (2032 mm), leaving about 12 inches of unused space across the container width. Ten pairs along the length give you 20 pallets.

Turned or Rotated Loading

By rotating some or all pallets 90 degrees — placing the 48-inch side against the wall — you change the math. Two pallets now span 96 inches (2438 mm), which is extremely tight against the 2350 mm internal width. In practice, this does not work for standard US pallets. However, for Euro pallets, rotation is a powerful tool. Alternating the orientation of Euro pallets in a pinwheel pattern can fill gaps and add one to three additional pallets compared to straight loading.

Pinwheel (Staggered) Loading

A pinwheel configuration alternates pallet orientation within each row or between rows. This interlocking pattern reduces dead space between pallets and against the container walls. It is most effective with Euro pallets because their rectangular proportions create complementary gaps when rotated. Skilled loaders using a pinwheel arrangement routinely fit 28 to 30 Euro pallets in a single layer.

Double Stacking

If your cargo's height permits it, double stacking effectively doubles your pallet count. A standard 40 ft container has 2.39 meters of internal height. Subtract the pallet height (approximately 15 cm) and you have about 2.24 meters for cargo on the bottom layer. If each layer of goods stands no taller than roughly 1.1 meters, you can fit a second pallet on top.

Double stacking requires that the bottom layer's cargo can bear the weight of the upper pallets without crushing, shifting, or collapsing. Goods like canned food, bottled water, and boxed hardware are excellent candidates. Always use slip sheets, interlocking patterns, or stretch wrap to stabilize double-stacked loads.

Key Factors That Affect Pallet Capacity

Even with the perfect loading configuration, several real-world factors can reduce the number of pallets you actually get into a container.

Weight Limits: A 40 ft dry container has a maximum payload of approximately 26,000 to 28,000 kg. If you are shipping dense goods, you will hit the weight limit long before you run out of floor space. Always check the container's CSC plate for its specific maximum gross weight, then subtract the tare weight (typically around 3,700 to 3,900 kg).

Cargo Overhang: If your goods extend beyond the edges of the pallet — even by a few centimeters — it can prevent pallets from sitting flush. This overhang eats into usable space and can reduce capacity by two or three pallets.

Reefer Containers: Refrigerated 40 ft containers have the same external dimensions but the insulation and refrigeration unit reduce internal space. Expect to lose one to two pallets compared to a dry container. Air circulation requirements also matter.

High Cube Containers: A 40 ft High Cube does not add floor space, so single-layer counts remain the same. The advantage is the extra foot of height, which makes double stacking feasible for taller cargo.

Road Weight Limits: In the United States, the typical gross vehicle weight limit is 80,000 lbs (about 36,287 kg). After accounting for the truck, chassis, and container weight, you may be limited to a payload of around 19,000 to 21,000 kg. European road limits differ. Always verify local regulations.

Practical Planning Tips for Optimal Loading

Measure Your Goods First: Before committing to a loading plan, measure the actual dimensions and weight of your packed, palletized goods — not just the product itself. Include stretch wrap, corner protectors, and any dunnage.

Use Loading Software: Container loading optimization software lets you input your pallet dimensions, cargo weights, and container type to generate a 3D visual loading plan. These tools also flag weight distribution issues.

Plan for Unloading Access: If your container will be partially unloaded at multiple stops, you need access lanes between pallets. For multi-stop deliveries, prioritize loading order over maximum density.

Secure the Load Properly:Use load bars between rows, dunnage bags in gaps, and plenty of stretch wrap on individual pallets. For heavy loads, consider ratchet straps anchored to the container's lashing rings.

Consider Pallet Quality: Broken or warped pallets reduce stacking stability. ISPM-15 heat-treated pallets are required for most international shipments to prevent pest transmission — make sure your pallets comply before loading.

The number of pallets that fit in a 40 ft container ranges from as few as 18 to as many as 60, depending on pallet type, loading configuration, stacking, and weight constraints. For the most common scenario — standard US pallets in a single layer with straight loading — plan for 20 pallets as your baseline. Euro pallets in a pinwheel arrangement push that to 28 to 30. Double stacking can double those figures when cargo weight and stability permit.
