A standard 40-foot shipping container fits 20 standard pallets (48″ x 40″) in a single layer. Depending on how you arrange them and whether you can double-stack, that number can range from 20 to 48. The actual count for your shipment depends on pallet size, product weight, stacking height, and how the pallets are oriented inside the container.
Standard Pallets in a Single Layer
The most common pallet in North America is the 48-inch by 40-inch wood stringer pallet. When loaded into a 40-foot container, 20 of these pallets fit on the floor in a straightforward arrangement. The container’s internal width is roughly 92 inches, which means two pallets placed side by side (each 40 inches wide) leave about 12 inches of unused space across the width. That gap is unavoidable with standard pallets, but it’s narrow enough that the configuration still works well for most shipments.
By rotating some pallets and experimenting with mixed orientations, shippers can sometimes squeeze in 22 to 24 standard pallets per layer. This pinwheel or interlocking approach alternates pallets between lengthwise and widthwise positions to fill more of the floor. The tradeoff is that loading and unloading takes longer, and forklift access can be trickier. If speed at the destination matters, sticking with the clean 20-pallet layout is often worth the small sacrifice in space.
Double-Stacking to 48 Pallets
If your goods are light enough and short enough, you can stack a second tier of pallets on top of the first. A standard 40-foot container has an internal height of about 7 feet 10 inches, while a 40-foot high cube container gives you roughly 8 feet 10 inches. With double stacking, a 40-foot container can hold up to 48 standard pallets.
Whether double stacking is practical comes down to two questions. First, can your products handle the compression? Fragile or irregularly shaped goods may not tolerate weight on top. Second, does the combined height of two loaded pallets fit under the container ceiling? A standard wood pallet is about 6 inches tall, so two pallets plus their cargo need to total less than the container’s interior height. If each loaded pallet stands 48 inches tall, two tiers would reach 96 inches, which fits inside a high cube container but would be tight in a standard one.
Euro Pallets and Other Sizes
Euro pallets measure 1200mm by 800mm (roughly 47″ x 31″), which is slightly narrower than the North American standard. In a regular 40-foot container, you can typically fit around 21 Euro pallets in a single layer. The smaller width allows a bit more flexibility in orientation.
Some carriers offer “pallet wide” containers, which are slightly wider than standard containers. These non-standard units are more common in European trade lanes and can accommodate 24 or 30 Euro pallets per layer. If you’re shipping Euro pallets in high volume, asking your freight forwarder about pallet wide availability could save you a container or two per shipment.
The International Organization for Standardization recognizes six pallet sizes under ISO 6780, each designed to optimize floor coverage in standard containers. If your product dimensions allow flexibility in pallet choice, testing a different size could meaningfully improve how many units you fit per container.
Weight Limits That Override Volume
Even if you have physical space for more pallets, weight restrictions may cap your load. A 40-foot dry container has a recommended maximum cargo weight of roughly 44,500 pounds (about 20 metric tons). Refrigerated 40-foot containers are typically limited to around 41,500 pounds of cargo.
These limits exist because over-the-road trucking in the U.S. is capped at 80,000 pounds gross vehicle weight, which includes the truck, chassis, container, and cargo combined. A typical 40-foot container weighs about 8,000 to 8,500 pounds empty, and the truck and chassis add roughly 30,000 more. That leaves your cargo allowance in the mid-40,000-pound range.
This matters most for dense products. If you’re shipping bottled beverages, machinery, or stone tile, you’ll hit the weight ceiling long before you run out of floor space. A single loaded pallet of heavy goods can weigh 2,000 pounds or more, meaning you might only safely load 20 to 22 pallets even with room for more. For lightweight goods like paper products or textiles, volume is the constraint, and double stacking becomes the better strategy.
Factors That Change Your Count
Several practical details can shift the number of pallets you actually load:
- Pallet loading height: Taller stacks per pallet mean fewer tiers fit vertically, which reduces total pallet count if you were planning to double-stack.
- Unloading requirements: If your customer needs to unload with a standard forklift, pallets must face a certain direction with enough clearance for fork entry. This can prevent some of the tighter interlocking arrangements.
- Overhanging cargo: Products that extend past the pallet edges effectively make each pallet larger, reducing how many fit side by side.
- Dunnage and bracing: Airbags, straps, or wood bracing used to secure cargo inside the container take up space. Budget a few inches of clearance on each side when planning your layout.
Quick Reference by Container Type
- 40-foot standard container, single layer: 20 standard pallets (up to 24 with optimized arrangement)
- 40-foot standard container, double-stacked: Up to 48 standard pallets
- 40-foot high cube container: Same floor count, but the extra 12 inches of height makes double stacking easier for taller loads
- 40-foot pallet wide container (Euro pallets): 24 to 30 Euro pallets per layer
Before finalizing your load plan, run the numbers on both volume and weight. The container that looks half empty might already be at its cargo weight limit, and the one packed to the ceiling might be well under. Balancing both constraints is how you get the most out of every shipment.
