How many pallets fit in a 20-ft and 40-ft container

Quick Overview

A standard 20-foot container usually fits 11 Euro pallets or 9–10 industrial pallets. A standard 40-foot container fits 24–25 Euro pallets or 20–21 industrial pallets in one floor tier. Actual capacity depends on pallet dimensions, overhang, cargo weight, stacking and container specifications.

How many pallets fit in a 20- and 40-foot container?

The number of pallets that fit in a shipping container depends primarily on the pallet dimensions and the container’s usable internal floor space.

For standard dry containers loaded in a single floor tier, the typical pallet capacities are:

These figures assume that the cargo does not extend beyond the edges of the pallets and that the pallets are arranged efficiently in a standard dry container. They refer to one floor tier and do not include double-stacking.

The final number may be lower when pallets have overhanging cargo, irregular packaging, restricted loading orientations or excessive weight.

Standard pallet sizes used in container shipping

Several pallet formats are used in international shipping. The three most relevant formats for containerized cargo are the Euro pallet, the industrial pallet and the North American GMA pallet.

Euro pallet or EPAL 1

The Euro pallet, also known as the EPAL 1 pallet, measures 1,200 × 800 mm. It is widely used across Europe and is designed for efficient handling, storage and road transport.

A standard 20-foot container can usually hold 11 Euro pallets, while a standard 40-foot container can hold approximately 24–25 Euro pallets in one tier.

Industrial pallet or EPAL 2

The EPAL 2 industrial pallet measures 1,200 × 1,000 mm. Its larger footprint makes it suitable for many industrial and heavy-duty applications.

A standard 20-foot container normally holds 9–10 industrial pallets, while a standard 40-foot container holds approximately 20–21 pallets.

North American GMA pallet

The most common pallet format in the United States and Canada measures 48 × 40 inches, or approximately 1,219 × 1,016 mm.

A 20-foot container typically accommodates about 10 of these pallets, depending on the arrangement. An optimized 40-foot container loading plan can carry up to 21 pallets.

ISO 6780 specifies the principal dimensions and tolerances of flat pallets used in intercontinental materials handling. However, the standard does not guarantee a fixed container capacity. The actual number still depends on pallet dimensions, container specifications and the selected loading pattern.

Internal dimensions of 20-foot and 40-foot containers

Standard dry containers have nominal external lengths of 20 or 40 feet, but their usable internal dimensions are slightly smaller.

Exact measurements, door openings, tare weights and payload limits can vary slightly by carrier, container manufacturer and equipment series. Confirm the specifications of the assigned container before finalizing the loading plan.

For more detailed equipment information, review the specifications of a 20-foot container or 40-foot container.

Does a High Cube container fit more pallets?

A 40-foot High Cube container normally has almost the same internal floor dimensions as a standard 40-foot container. Its main advantage is additional internal height.

Therefore, a High Cube container does not usually provide more pallet positions in a single floor tier. It may allow cargo to be loaded higher or pallets to be double-stacked when:

• The cargo is structurally suitable for stacking.
• The bottom pallets can support the additional load.
• The total cargo weight remains within the container payload.
• The pallets can be loaded and unloaded safely.
• The cargo is properly secured against movement.
• Road and inland transport weight limits are not exceeded.

Double-stacking should never be assumed solely because a High Cube container has more height.

Standard containers vs. Pallet Wide containers

A Pallet Wide container has additional internal width and is designed to improve pallet utilization.

The difference is especially relevant for Euro pallets:

A 40-foot Pallet Wide High Cube can carry 30 Euro pallets, compared with approximately 24–25 in a standard 40-foot container. A 45-foot Pallet Wide High Cube can carry approximately 33 Euro pallets.

Pallet Wide containers are not available on every route. Availability should be confirmed with the carrier or freight forwarder before the shipment is planned.

What affects the number of pallets you can load?

The theoretical pallet count is only a starting point. Several cargo and operational factors can reduce the number that can be loaded safely.

Pallet overhang

Boxes, bags or other cargo should not extend beyond the pallet edges. Even a small amount of overhang can prevent pallets from fitting into the intended arrangement.

Overhanging cargo is also more exposed to crushing, tearing and impact during handling.

Pallet loading height

The total height includes both the pallet and the cargo placed on it. Pallet height determines whether the cargo can fit through the container door and whether double-stacking is possible.

Measure the finished palletized load rather than relying only on the product dimensions.

Cargo and pallet weight

A container may have enough floor space for the planned number of pallets but still exceed its permitted payload or an applicable road weight limit.

Calculate the combined weight of:

• The goods
• The pallets
• Packaging materials
• Securing materials
• The empty container

Heavy pallets should also be distributed evenly to avoid excessive concentrated loads and poor weight balance.

Cargo stackability

Not all palletized cargo can be double-stacked. Fragile goods, flexible cartons, drums, irregular machinery and pallets with limited load-bearing strength may require single-tier loading.

The shipper should confirm the maximum permitted top load and stacking configuration with the supplier or packaging provider.

Loading and unloading requirements

The pallet arrangement must account for the equipment available at origin and destination.

Consider:

• Forklift access
• Dock height
• Container door dimensions
• Side or rear unloading restrictions
• The sequence in which pallets need to be removed
• Warehouse ceiling and doorway clearances
• Final-mile vehicle limitations

The arrangement that maximizes pallet capacity may not always be the arrangement that enables the safest or most efficient unloading process.

How to pack pallets for container shipping

Correct pallet preparation reduces cargo movement and helps make the best use of the available container space.

• Keep cargo within the pallet footprint. Boxes and other goods should not extend beyond the pallet edges.
• Use a stable stacking pattern. Align cartons carefully and avoid uneven columns or unstable pyramid-shaped loads.
• Distribute weight evenly. Place heavier items at the bottom and avoid concentrating excessive weight on one part of the pallet.
• Use stretch wrap correctly. Secure the load to the pallet rather than wrapping only the cartons together.
• Add suitable strapping. Plastic or steel strapping may be required for heavy, dense or unstable cargo.
• Protect corners and edges. Edge protectors help prevent straps and wrapping from damaging cartons.
• Use blocking, bracing or lashing where required. Pallet wrap alone may not prevent cargo from moving inside the container.
• Avoid damaged pallets. Do not use pallets with broken boards, loose blocks, protruding nails or visible structural damage.
• Keep labels visible. Shipping marks, handling labels and identification numbers should remain readable after wrapping.
• Confirm moisture protection. Use suitable liners, desiccants or other moisture-control measures when the cargo is sensitive to condensation.

The appropriate securing method depends on the product, its weight, the route and the expected forces during inland and ocean transportation.

ISPM 15 requirements for wooden pallets

Solid-wood pallets used in international trade may need to comply with ISPM 15, the international standard for wood packaging material.

ISPM 15 is intended to reduce the risk of pests being transported between countries in untreated raw wood packaging. Regulated wood packaging may include pallets, crates, boxes, skids and wooden dunnage.

When the destination country requires ISPM 15 compliance, wooden pallets generally need to:

• Receive an approved treatment.
• Be produced or treated by an authorized provider.
• Display a valid and legible IPPC mark.
• Remain free from untreated replacement components.

Packaging made entirely from processed wood materials, such as plywood, particle board or oriented strand board, is generally outside the scope of ISPM 15 because the manufacturing process removes the relevant pest risk. Mixed packaging containing both processed and raw wood may still need compliant treatment and marking.

Always check the import requirements of the destination country before shipping.

Choosing between FCL and LCL for palletized cargo

A shipment does not need to fill every pallet position to use a full container.

FCL shipping provides the shipper with the use of an entire container. It may be suitable when the cargo volume is high, the shipment requires greater separation from other cargo or the shipper wants more control over container loading.

LCL shipping consolidates cargo from multiple shippers in one container. It is commonly used for smaller palletized shipments that do not require a complete container.

The most economical option depends on the number of pallets, total volume, weight, origin, destination, handling requirements and current freight rates.
