Pallet Wood Dimensions Guide
Understanding pallet wood dimensions is essential whether you work in logistics, build furniture from reclaimed lumber, or need to specify the right pallet for international shipments. Pallets may look simple, but their component sizes follow established standards that vary by region, construction style, and intended load capacity. This guide breaks down the exact measurements for every major pallet format so you can find the numbers you need quickly and confidently.
Pallet Construction Overview
Before diving into specific measurements, it helps to understand the four main components that make up a standard wooden pallet. Each part serves a distinct structural purpose, and the dimensions of these components determine the overall strength, weight, and compatibility of the finished pallet.
Top deck boards are the planks that form the upper surface of the pallet. Cargo sits directly on these boards, so their width, thickness, and spacing influence how evenly weight is distributed. A typical pallet has five to seven top deck boards arranged across the width of the frame, with narrow gaps between them to allow airflow and reduce overall weight.
Bottom deck boards run along the underside of the pallet and provide contact points with the floor, racking, or conveyor system. Pallets usually have three bottom deck boards, though some heavy-duty designs use five. Bottom boards are often slightly narrower than top boards because they bear less direct load from the cargo above.
Stringers are the long structural members that connect the top and bottom decks on a stringer pallet. They run the full length of the pallet and are typically notched to allow forklift entry from two sides. Stringers are the primary load-bearing element and are made from denser hardwood or engineered lumber to resist bending under heavy cargo.
Blocks are short, solid wood segments used in block-style pallets instead of continuous stringers. A standard block pallet uses nine blocks arranged in a three-by-three grid at the corners, center edges, and middle of the pallet. Block construction allows four-way forklift access, which makes these pallets easier to handle in tight warehouse spaces.
North American Standards (GMA)
The Grocery Manufacturers Association pallet, commonly called the GMA pallet, is the dominant standard in the United States, Canada, and Mexico. Its overall footprint measures 48 inches long by 40 inches wide, a size originally chosen to fit efficiently inside standard North American truck trailers and rail cars. Roughly 30 percent of all new pallets produced in the United States follow this specification, making it the single most common pallet size on the continent.
The individual component dimensions of a GMA pallet follow well-established guidelines. Top deck boards are 40 inches long, running across the width of the pallet. Each board is typically 3.25 to 3.5 inches wide and about 5/16 of an inch (roughly 8 millimeters) thick. A standard GMA pallet uses five to seven top deck boards, with the leading and trailing boards sometimes being slightly wider than the interior boards to provide additional edge support.
Stringers on GMA pallets run 48 inches long and have a cross section of approximately 3.5 inches tall by 1.5 inches wide. Most GMA pallets use three stringers spaced evenly across the width of the deck. Each stringer includes two notches cut into its lower half to allow forklift tines to enter from the front or back. The notches are typically about 9 inches wide and 1.5 inches deep, leaving enough solid wood above to maintain structural integrity.
Bottom deck boards on a GMA pallet mirror the length of the top boards at 40 inches but are often narrower, around 3.25 inches wide. Three bottom boards are standard, aligned directly beneath the three stringers to provide stable floor contact. The overall assembled height of a GMA stringer pallet ranges from about 5 to 6.5 inches depending on exact board and stringer thicknesses used by the manufacturer.
While the 48 by 40 inch size dominates, North America also uses several secondary pallet sizes for specific industries. The 42 by 42 inch pallet is popular in the telecommunications and paint sectors, the 48 by 48 inch format suits the drum and barrel industry, and the 48 by 42 inch size is common in chemical and beverage shipping. Each of these variants uses similar deck board and stringer proportions scaled to the larger or smaller footprint.
European and ISO Standards
The European Pallet Association manages the EUR pallet system, with the EUR 1 pallet being the most widely used format across Europe. The EUR 1 measures 800 millimeters wide by 1200 millimeters long (approximately 31.5 by 47.2 inches). Unlike the GMA stringer pallet, the EUR 1 uses a block construction with nine solid wood blocks that allow full four-way forklift access.
EUR pallets follow strict dimensional tolerances. The overall height of a EUR 1 pallet is 144 to 162 millimeters (about 5.7 to 6.4 inches), depending on whether the pallet is new or has been repaired. Top deck boards are22 millimeters thick (just under 7/8 of an inch), which is noticeably thicker than the typical GMA deck board. This additional thickness contributes to the EUR pallet's higher maximum static load capacity of around 4000 kilograms compared to the GMA standard of about 2500 kilograms.
The EUR 1 uses five top deck boards of two different widths. The three wider boards measure 145 millimeters across, while the two narrower boards are100 millimeters wide. Bottom boards follow a similar pattern with three boards, the center board being wider than the two outer boards. All boards are chamfered on their top edges to reduce splintering during handling.
The blocks on a EUR pallet measure approximately 145 by 100 by 78 millimeters for the corner and center edge positions, with the center block sometimes being slightly larger. These blocks are made from pressed wood chips or solid softwood and connect the top and bottom decks using spiral or ring-shank nails. The ISO also recognizes several other EUR sizes, including the EUR 2 at 1000 by 1200 millimeters, the EUR 3 at 1000 by 1200 millimeters with a different board layout, and the EUR 6 at 800 by 600 millimeters as a half-pallet for retail display use.
Other Regional Pallet Sizes
Australia uses a distinctive square pallet that measures 1165 by 1165 millimeters (approximately 45.9 by 45.9 inches). This format was designed to optimize space inside Australian standard shipping containers and rail cars. The Australian pallet typically uses a block construction and is built with hardwood native to the region, giving it exceptional durability in the harsh climate conditions that pallets face during overland transport across the continent.
Asian markets rely on two primary pallet sizes. The 1100 by 1100 millimeter (43.3 by 43.3 inch) square pallet is the preferred format in Japan and South Korea. It was developed to fit the slightly narrower truck beds common in those countries and is often made from lightweight softwood or engineered wood composites to keep shipping weights low. Japan's pallet industry places a strong emphasis on precision manufacturing, and the 1100 by 1100 format has very tight dimensional tolerances.
China and much of Southeast Asia favor the 1000 by 1200 millimeter (39.4 by 47.2 inch) pallet, which closely aligns with the European EUR 2 size. This overlap is no coincidence, as trade routes between Asia and Europe make compatibility between the two formats commercially valuable. Pallets built to this size in Asia are typically made from plantation-grown pine or poplar, materials that are widely available and relatively inexpensive compared to the hardwoods used in Australia.
Other sizes worth noting include the 1067 by 1067 millimeter (42 by 42 inch) pallet used in parts of North America and Australia for specific industries, and the 1100 by 1100 millimeter format that the ISO recognizes as one of its six global standard sizes. Each region developed its preferred dimensions based on local truck widths, warehouse racking standards, and shipping container dimensions, which explains why no single global pallet size has ever achieved universal adoption.
Regional Comparison Table
The table below summarizes the key dimensions for each major regional pallet standard. All measurements are listed in both millimeters and inches where applicable.
| Region / Standard | Length | Width | Height (approx.) | Construction |
|---|---|---|---|---|
| North America (GMA) | 1219 mm (48″) | 1016 mm (40″) | 127–165 mm (5–6.5″) | Stringer |
| Europe (EUR 1) | 1200 mm (47.2″) | 800 mm (31.5″) | 144–162 mm (5.7–6.4″) | Block |
| Australia | 1165 mm (45.9″) | 1165 mm (45.9″) | 150 mm (5.9″) | Block |
| Asia (Japan/Korea) | 1100 mm (43.3″) | 1100 mm (43.3″) | 130–150 mm (5.1–5.9″) | Block |
| Asia (China/SE Asia) | 1200 mm (47.2″) | 1000 mm (39.4″) | 130–150 mm (5.1–5.9″) | Block |
Board thickness also varies across standards. GMA deck boards are about 8 millimeters (5/16 of an inch) thick, while EUR boards measure 22 millimeters (7/8 of an inch). Australian and Asian pallets generally fall between 18 and 22 millimeters depending on the manufacturer and intended load capacity.
Applications and Safety Tips
Whether you are selecting pallets for commercial shipping or sourcing reclaimed pallet lumber for woodworking, a few practical considerations will help you make better decisions and stay safe.
Check for ISPM 15 stamps. The International Standards for Phytosanitary Measures No. 15 require all wood packaging used in international trade to be treated against pests. Every compliant pallet carries a stamp showing the treatment method and country of origin. Look for the HT code, which indicates the pallet was heat treated to a core temperature of 56 degrees Celsius for at least 30 minutes. Heat-treated pallets are safe for most repurposing projects. Avoid pallets stamped with MB, which means they were fumigated with methyl bromide, a toxic chemical that is being phased out globally but still appears on older pallets.
Inspect reclaimed wood carefully. Pallet wood that has spent years in a supply chain may have absorbed chemicals from the products it carried, been exposed to weather and moisture, or developed mold in hidden areas between boards. Before using reclaimed pallet lumber for furniture, planters, or any indoor project, inspect each board for stains, discoloration, unusual odors, and signs of fungal growth. Discard any boards that look or smell suspicious.
Wear protective equipment. Pallet wood is rough-sawn, full of splinters, and often contains old nails, staples, or broken fasteners embedded in the grain. Always wear heavy work gloves when disassembling pallets, safety glasses when cutting or sanding, and a dust mask or respirator to avoid inhaling wood dust. Pallet wood dust can be especially irritating because the lumber is typically dried out and may contain residues from its treatment process.
Match the pallet to the load. If you are selecting pallets for shipping, make sure the pallet size matches both your cargo footprint and the destination country's preferred format. Sending GMA-sized pallets to a European warehouse with EUR-configured racking creates handling problems and potential safety hazards. Consult your freight carrier or logistics provider to confirm the correct pallet dimensions before building or purchasing pallets for international shipments.
Consider weight ratings. Every pallet has static, dynamic, and racking load limits that depend on its construction and the species of wood used. A standard GMA stringer pallet supports about 2500 kilograms in a static stack but only around 1000 kilograms when stored on warehouse racking with unsupported spans. EUR block pallets handle higher loads due to their thicker boards and nine-block support structure. Always verify the weight rating with the pallet manufacturer rather than relying on general guidelines, especially for heavy or fragile cargo.
Frequently Asked Questions
The standard North American pallet follows the Grocery Manufacturers Association (GMA) specification and measures 48 inches long by 40 inches wide. This size accounts for roughly 30 percent of all new pallets produced in the United States and is the dominant format used across grocery, retail, and general freight industries.
The overall height of a GMA pallet typically falls between 5 and 7 inches depending on whether it uses a stringer or block construction. Individual deck boards on these pallets are usually 40 inches long, 3.25 to 3.5 inches wide, and about 5/16 of an inch thick, while stringers run 48 inches long with a cross section of approximately 3.5 by 1.5 inches.
Pallet deck board thickness varies by region and intended load capacity. In North America, most GMA pallet deck boards are roughly 5/16 of an inch thick, which translates to about 8 millimeters. This thickness provides a reliable balance between weight capacity and overall pallet weight.
European EUR pallets use slightly thicker deck boards at 22 millimeters, which is just under 7/8 of an inch. Thicker boards contribute to the higher load ratings that EUR pallets are known for. Heavy-duty and custom pallets in any region may feature boards as thick as 1 inch or more to handle specialized cargo.
Stringer pallets use two or three long boards, called stringers, running the full length of the pallet to support the deck boards. The stringers usually have notches cut into them so forklift tines can slide underneath from the front or back. Most standard GMA pallets in North America are stringer pallets because they are less expensive to manufacture.
Block pallets replace the continuous stringers with solid wood blocks positioned at the corners, center edges, and sometimes the middle of the pallet. These blocks allow forklifts and pallet jacks to access the pallet from all four sides, which makes block pallets more versatile in warehouses with limited maneuvering space. European EUR pallets and many international formats use the block design as their standard construction.
No, pallet dimensions differ significantly around the world. The ISO recognizes six standard pallet sizes, and individual countries or regions often favor their own preferred dimensions. North America primarily uses the 48 by 40 inch GMA pallet, Europe relies on the 800 by 1200 millimeter EUR pallet, and Australia uses its own 1165 by 1165 millimeter square format.
Asia adds further variety with both the 1100 by 1100 millimeter size common in Japan and Korea and the 1000 by 1200 millimeter size used widely across China and Southeast Asia. These differences developed over decades based on local truck widths, container sizes, and warehouse rack systems, which is why a single global standard has never fully taken hold.
Reclaimed pallet wood can be safe for many projects, but you need to inspect it carefully before use. Look for the ISPM 15 treatment stamp on any pallet you plan to repurpose. Pallets stamped with HT were heat treated and are generally considered safe. Avoid any pallet stamped with MB, which indicates it was fumigated with methyl bromide, a toxic chemical that can linger in the wood fibers.
Beyond the treatment stamp, consider what the pallet carried during its service life. Pallets used to ship food or dry goods are typically cleaner than those from chemical or industrial supply chains. Inspect the wood for visible stains, mold, or strong chemical odors. Wear gloves and a dust mask when cutting or sanding reclaimed pallet wood, and never use questionable pallet lumber for items that will come into direct contact with food.
