Wooden pallets are the backbone of modern logistics. Every day, billions of dollars worth of goods travel across warehouses, loading docks, and ocean containers stacked on these simple yet essential platforms. Despite their importance, many business owners, warehouse managers, and shipping coordinators are unsure about the exact dimensions of the pallets they use — or should be using. Choosing the wrong pallet size can lead to wasted truck space, damaged products, and unnecessary shipping costs.
Understanding pallet dimensions is not just a matter of trivia. It directly affects how efficiently you can load a trailer, whether your goods will fit through standard doorways, and how safely your products will travel from point A to point B. In this guide, we will break down the standard wooden pallet sizes used across North America and the rest of the world, explain how to measure a pallet correctly, and help you choose the right dimension for your specific needs.
Standard Wooden Pallet Size in North America
48 x 40 Inches and Height
The most widely used wooden pallet in the United States and Canada is the 48 x 40 inch pallet, often referred to as the GMA pallet. GMA stands for the Grocery Manufacturers Association, which originally standardized this size for the grocery and consumer goods industries. Over time, this pallet became the de facto standard across nearly every sector of the North American supply chain, from retail and food service to pharmaceuticals and automotive parts.
The 48-inch dimension refers to the length of the pallet — the side that runs along the length of the stringer boards. The 40-inch dimension is the width, which runs parallel to the deck boards. According to industry estimates, the GMA pallet accounts for approximately 30 percent of all new wooden pallets produced in the United States each year, and when you include pallets already in circulation, its market share is even larger.
The typical height of a standard GMA pallet ranges from 5.5 to 6.5 inches, depending on the construction style and the thickness of the lumber used. Most commonly, you will find these pallets standing about 6 inches tall. This height includes the top deck boards, the bottom deck boards, and the stringers or stringer boards that run between them.
For those who work in international shipping or need metric measurements, the 48 x 40 inch pallet translates to approximately 1219 x 1016 millimeters, or roughly 1200 x 1000 mm when rounded. This is close to, but not identical to, some international pallet standards, which can occasionally cause compatibility issues when shipping goods between North America and other regions.
The weight of a standard 48 x 40 wooden pallet typically falls between 35 and 50 pounds, depending on the type of wood used and the specific construction. Hardwood pallets tend to be heavier but more durable, while softwood pallets are lighter and more affordable. The dynamic load capacity generally ranges from 2,500 to 2,800 pounds for a well-built GMA pallet. Static load capacity can be significantly higher, often reaching 5,000 pounds or more.
Other Common Wooden Pallet Dimensions
Popular Sizes by Region and Industry
While the 48 x 40 inch pallet dominates North America, it is far from the only pallet size in use around the world. The International Organization for Standardization (ISO) recognizes six standard pallet dimensions for global trade. Each of these sizes is associated with a particular region or industry, and understanding them is essential if you ship goods internationally.
The most prominent alternative is the Euro pallet, also known as the EUR pallet or EPAL pallet. This pallet measures 800 x 1200 millimeters, which is approximately 31.5 x 47.2 inches. The Euro pallet is the dominant standard across most of Europe. One of its key advantages is its exchange pool — companies can swap loaded pallets for empty ones at various points in the supply chain, reducing the need to track and return individual pallets. The standard height is 144 millimeters, or roughly 5.7 inches.
Another widely used international size is the 1000 x 1200 millimeter pallet, common in Europe, Asia, and parts of the Middle East, frequently used in the automotive and chemical industries. The Australian standard pallet measures 1165 x 1165 millimeters, a square design optimized for Australian rail cars and shipping containers. In Asia, particularly Japan and South Korea, pallets measuring 1100 x 1100 millimeters are popular because they fit efficiently into shipping containers used for Pacific Rim trade.
Beyond these international standards, several industry-specific pallet sizes are common in North America. The beverage industry often uses 48 x 48 inch pallets for stacking cases of bottles and cans. The telecommunications and paint industries frequently rely on 42 x 42 inch pallets. The United States military uses the 40 x 48 inch pallet — the same dimensions as the GMA pallet but with the orientation reversed, built to stricter specifications for durability and air transport.
Custom pallet sizes are also available and surprisingly common. If none of the standard sizes align with your product dimensions or shipping requirements, pallet manufacturers can build pallets to virtually any specification. Custom pallets cost more, but the investment can pay for itself through improved load efficiency and reduced product damage.
How to Measure a Wooden Pallet Correctly
Length, Width, and Height Definitions
Measuring a wooden pallet seems straightforward, but there are common mistakes that can lead to ordering the wrong size or miscalculating load plans. The industry convention for stating pallet dimensions is length by width, expressed as L x W.
For stringer pallets — the most common type in North America — the length is the dimension that runs along the stringer boards. Stringers are the long, solid boards that run between the top and bottom deck boards and provide the pallet’s structural support. The width is the measurement taken perpendicular to the stringers, running across the deck boards from one side to the other.
For block pallets, which use blocks of solid wood at the corners and along the edges instead of full-length stringers, the length is typically the longer of the two horizontal dimensions, and the width is the shorter. In the case of a square pallet, either side can be considered the length or width.
When measuring height, account for all three layers of the pallet: the bottom deck boards, the stringers or blocks, and the top deck boards. Standard deck boards are usually about five-eighths to three-quarters of an inch thick, and stringers typically stand about 3.5 inches tall. A common mistake is to measure only the stringer height or forget to include the bottom deck boards.
It is also important to measure the actual pallet rather than relying solely on its stated dimensions. Wooden pallets are manufactured products, and there is always some degree of variation due to wood shrinkage, manufacturing tolerances, and wear. A pallet that is nominally 48 x 40 inches might actually measure 47.75 x 39.875 inches in practice. For most applications, this small difference does not matter, but if you are designing racking systems or loading containers with very tight tolerances, even a quarter-inch discrepancy can cause problems.
Choosing the Right Pallet Dimension for Your Needs
Factors That Influence Pallet Size Selection
Selecting the correct pallet size involves balancing several factors, including the dimensions of your products, the capacity of your handling equipment, the size of your storage and shipping spaces, and cost considerations. Making the right choice can improve your shipping efficiency by ten percent or more, while making the wrong choice can lead to wasted space, product damage, and higher freight bills.
The first and most important factor is the size of the products you are shipping. Ideally, your boxes or containers should fit on the pallet with minimal overhang and minimal wasted space. Efficient arrangement reduces the risk of product shifting during transit and maximizes the number of units you can fit on each pallet.
Doorway and container constraints are another critical consideration. Standard single doorways in commercial buildings are typically 36 inches wide, which means a 48 x 40 inch pallet can only pass through turned on its short side. Standard 20-foot and 40-foot ocean shipping containers have interior widths of approximately 92 inches, which means you can fit two 40-inch-wide pallets side by side. Standard 53-foot domestic trailers have an interior width of about 98.5 inches.
Your handling equipment also plays a role. Standard forklifts and pallet jacks are designed to work with 48 x 40 inch pallets. Block pallets offer the advantage of four-way entry, meaning a forklift can pick them up from any side. Stringer pallets typically offer two-way entry unless notched.
Weight capacity is another important factor. Heavier loads generally require thicker deck boards, closer board spacing, and hardwood construction. Always verify that the pallet’s rated load capacity exceeds your actual load weight, and build in a safety margin of at least 20 percent.
Cost is always a factor. Standard 48 x 40 inch pallets are the least expensive option in North America because they are produced in the highest volumes. If cost is a primary concern, try to design your packaging to fit standard pallet sizes rather than ordering custom pallets.
Finally, consider the destination of your shipments. If you are exporting goods to Europe, it may make sense to use Euro pallets from the start. Some countries also have regulations regarding the treatment of wooden pallets to prevent the spread of invasive insects. The international standard for this is ISPM 15, which requires that wooden pallets used in international trade be heat-treated or fumigated and stamped with a certification mark.
