How Many Pallets Fit in a 20' Container
Understanding how many pallets fit inside a 20-foot shipping container is one of the most practical questions in freight logistics. Whether you are shipping consumer goods across the Atlantic, moving inventory between warehouses, or coordinating an international trade deal, getting the pallet count right determines your cost per unit, your truck-to-port scheduling, and ultimately your bottom line. The short answer is that a standard 20-foot container typically holds 10 to 11 pallets in a single layer, but the real answer depends on pallet type, loading orientation, stacking strategy, and the specific container variant you are using.
This guide breaks down every variable so you can plan loads with confidence, avoid costly surprises at the port, and maximize the cubic footage you are paying for.
Standard 20-Foot Container Dimensions
Before you can calculate pallet capacity, you need to know exactly how much space you are working with. A standard 20-foot dry container, often called a TEU (Twenty-foot Equivalent Unit), has the following nominal dimensions:
| Measurement | External | Internal |
|---|---|---|
| Length | 20 ft (6.058 m) | 19 ft 4 in (5.898 m) |
| Width | 8 ft (2.438 m) | 7 ft 8 in (2.352 m) |
| Height | 8 ft 6 in (2.591 m) | 7 ft 10 in (2.393 m) |
The difference between external and internal measurements matters more than most shippers realize. The corrugated steel walls, floor boards, and corner castings consume roughly 6 to 8 inches on each side. That means your usable floor space is approximately 233 inches long by 92 inches wide, giving you about 148 square feet of floor area. The usable height of just under 94 inches is critical when you start thinking about double-stacking pallets.
It is also worth noting that the door opening is slightly narrower than the interior width. Most 20-foot containers have a door width of about 7 feet 6 inches (2.286 m), which can create a bottleneck when loading wider pallets with a forklift. Always measure the door opening of your specific container before finalizing a loading plan.
Common Pallet Types and Their Dimensions
Not all pallets are created equal, and the type you use has a direct impact on how many fit inside a container. The two most common pallet standards in international shipping are the GMA pallet (used primarily in North America) and the EUR pallet (dominant across Europe).
Standard American Pallet (GMA / 48" x 40")
The Grocery Manufacturers Association pallet, measuring 48 inches long by 40 inches wide, is the workhorse of the North American supply chain. Roughly 30 percent of all pallets produced in the United States follow this specification. When loaded into a 20-foot container, these pallets are typically arranged in two rows of five, with the 40-inch side facing the container wall and the 48-inch side running along the container's length. This configuration yields 10 pallets per single layer.
The math works out cleanly: two pallets side by side at 40 inches each consume 80 inches of the container's 92-inch internal width, leaving about 12 inches of clearance. Along the length, five pallets at 48 inches each use 240 inches of the available 233 inches, which means in practice you may need to angle the last pallet slightly or accept a snug fit.
Euro Pallet (EUR / 1200mm x 800mm)
The Euro pallet measures 1200mm by 800mm, which converts to approximately 47.24 inches by 31.50 inches. Its narrower width is specifically designed to optimize space inside ISO shipping containers and European truck trailers. When loaded into a 20-foot container, Euro pallets can be arranged to fit 11 pallets in a single layer, and some experienced loaders manage to squeeze in 12 by alternating the orientation of certain rows.
This dimensional efficiency is one of the key reasons European shippers prefer the EUR standard for containerized freight. Half-pallets (800mm x 600mm) can fit up to 24 units in a single layer, making them popular for retail distribution.
Loading Configurations: Single-Stack vs. Double-Stack
Single-stacking means placing one layer of pallets on the container floor with no pallets stacked on top. This is the safest approach and the default for fragile, top-heavy, or irregularly shaped cargo. With single-stacking, a 20-foot container holds 10 standard GMA pallets or 11 Euro pallets. Single-stacking leaves significant vertical space unused, with 30 to 40 inches of empty air above cargo that stands 48 to 60 inches tall.
| Pallet Type | Single-Stack | Double-Stack |
|---|---|---|
| Standard (GMA) | 10 | 20 |
| Euro (EUR) | 11 | 22 |
Double-stacking places a second layer of pallets directly on top of the first. This works well for durable goods such as canned food, bottled beverages, boxed hardware, or packaged dry goods. Two conditions must be met: the combined height of two palletized loads must not exceed 7 feet 10 inches, and the total weight must stay within the container's maximum payload capacity of 27,600 to 28,200 kg. Weight is often the limiting factor before height becomes an issue.
Key Factors That Affect Pallet Count
Pallet Orientation: How you orient each pallet changes the geometry of the entire load. Experienced freight planners often test multiple orientations to find the optimal arrangement. Euro pallets benefit from orientation flexibility more than GMA pallets because their 800mm width divides more efficiently into the container width.
Weight and Height Restrictions: Every container has a maximum gross weight stamped on its CSC plate, typically 30,480 kg for a 20-foot container. Heavy goods like stone or metal parts often hit the weight limit before filling the volume. Lightweight goods like textiles cube out first.
Forklift Access: If a forklift must enter the container for unloading, you need an internal aisle. This reduces capacity to 8 or 9 pallets. Many shippers avoid this by using containers that will be fully destuffed from the door end.
Container Variants: High-cube 20-foot containers offer an extra foot of height. Pallet-wide containers with 2,440mm interior width can fit one or two additional pallets per load.
How to Calculate Pallet Fit Yourself
A simple formula works for most situations. Start with the container's internal dimensions in millimeters. Divide the internal length (5,898mm) by the pallet length. For a GMA pallet at 1,219mm, you get 4.84, which rounds down to 4. Divide the internal width (2,352mm) by the pallet width. For GMA at 1,016mm, you get 2.31, meaning 2 across. Multiply for a base count of 8, then check bonus positions. The remaining length (1,022mm) nearly matches the 1,016mm width, so you can fit one more rotated pallet per row, bringing the total to 10.
Always subtract approximately 125 to 150mm from the internal length to account for the door frame recess and any protective dunnage. This small adjustment can mean the difference between a plan that works on paper and one that works in the real world.
Practical Loading Examples
Consumer Electronics on GMA Pallets
An electronics distributor needed to ship television sets to a European retailer. Each GMA pallet carried four boxed TVs and stood 52 inches tall. Single-stacking 10 pallets used 52 inches of the available 94-inch height, leaving 42 inches unused. However, the TVs were too fragile to double-stack, so the shipper accepted 10 pallets per container and negotiated a per-unit freight rate.
Canned Goods on Euro Pallets, Double-Stacked
A food manufacturer regularly ships canned soups to North Africa. Each Euro pallet of canned goods weighs approximately 900 kg and stands 1,050mm tall. Two stacked pallets reach 2,100mm, comfortably under the 2,393mm ceiling. The total weight of 22 double-stacked Euro pallets comes to 19,800 kg, well within the payload limit. This represents one of the most efficient loading scenarios possible.
Mixed Load with Forklift Access
A warehousing firm needed forklift access inside the container for partial unloading at multiple stops. They loaded only 8 GMA pallets in a staggered arrangement, leaving a center aisle wide enough for a narrow-aisle forklift. While this sacrificed two pallet positions, it saved significant labor time at each delivery point.
Final Recommendations
Getting the most out of a 20-foot container comes down to matching your pallet type, cargo characteristics, and unloading requirements to the right configuration. For maximum capacity with standard pallets, plan for 10 single-stacked or 20 double-stacked. For Euro pallets, aim for 11 single-stacked or 22 double-stacked. Always verify weight limits before committing to double-stacking, and leave door-end clearance for safe loading and unloading.
When in doubt, request a container loading plan from your freight forwarder. Most logistics providers use specialized software that accounts for pallet dimensions, weight distribution, container type, and regulatory requirements. A few minutes of planning can save thousands of dollars in wasted space or rejected shipments at the port of entry.
Frequently Asked Questions
A standard 20-foot container holds 10 GMA pallets (48x40 inches) or 11 Euro pallets (1200x800mm) in a single layer. If your cargo and pallets support double-stacking, you can fit 20 GMA pallets or 22 Euro pallets by placing a second layer on top.
The exact number depends on pallet orientation, cargo overhang, weight limits, and whether you need forklift access inside the container. In practice, most shippers achieve these standard numbers with careful loading.
Yes, double-stacking is possible when two conditions are met. First, each palletized load must be short enough that two stacked layers fit under the container ceiling of 7 feet 10 inches. Second, the total weight must stay within the payload limit of roughly 28,000 kg.
The lower tier must also be strong enough to support the upper tier without crushing. Double-stacking works well for durable, uniformly shaped goods like canned food, boxed hardware, or bottled beverages. Fragile or top-heavy cargo should not be double-stacked.
A standard 20-foot container has a maximum gross weight of approximately 30,480 kg (67,200 lbs), which includes the container itself. After subtracting the container tare weight of about 2,200 kg, the maximum payload capacity is roughly 28,000 kg (61,700 lbs).
In practice, road weight limits may further restrict your load. In the United States, the typical over-the-road limit is around 44,000 lbs gross for a loaded container on a chassis. Always check both the container rating and local road regulations.
GMA pallets measure 48x40 inches and are standard in North America. They fit 10 per layer in a 20-foot container, arranged as two rows of five. Euro pallets measure 1200x800mm (about 47x31 inches) and are narrower, allowing 11 per layer with optimized placement.
Euro pallets offer roughly 10 percent more pallet positions per container due to their narrower width, which divides more efficiently into the container floor space. The choice between them typically depends on your trade lane and destination market standards.
Start with the container internal dimensions: 5,898mm long by 2,352mm wide. Divide the length by your pallet length and the width by your pallet width, rounding down each result. Multiply to get your base count, then check if leftover space can fit additional rotated pallets.
For GMA pallets: 5,898 divided by 1,219mm gives 4 pallets per row, times 2 across gives 8, plus 2 bonus positions from rotating pallets in the remaining length, totaling 10. Always subtract 125-150mm from the length for door frame clearance.
