Pallet Size Guide
The right pallet size depends on your product dimensions, warehouse racking, truck configuration, and industry standards. This comprehensive guide covers every common pallet dimension used in North America and beyond — plus the anatomy, construction types, and measurement techniques you need to make an informed decision.

Pallet Anatomy
Understanding the parts of a pallet helps you communicate exactly what you need — whether you are ordering new pallets, requesting repairs, or evaluating recycled inventory.
Deck Boards (Top)
The flat boards on the top surface where cargo sits. Typically 5 to 7 boards running across the pallet width. Board width and spacing affect how evenly weight is distributed. Closer spacing supports smaller, heavier items better.
Bottom Boards
Boards on the underside that contact the warehouse floor or racking beams. Usually 3 to 5 boards. They protect stringers from abrasion, provide sliding surfaces, and distribute weight across racking beams for stable storage.
Stringers
The long structural members (typically 2×4 lumber) that run the full length of the pallet between the top and bottom deck boards. They carry the load and define the pallet's height. Stringer pallets have 3 stringers — one on each edge and one in the center.
Blocks
Solid wood blocks (usually 4×4 or 3.5×3.5 lumber) placed at the four corners, the center of each edge, and the center of the pallet. Block pallets use 9 blocks total and are inherently 4-way entry because blocks leave gaps for fork entry on all sides.
Notches
Semi-circular or rectangular cutouts in the bottom edge of stringers that allow forklift tines to enter from the side (creating partial 4-way entry on a stringer pallet). Without notches, a stringer pallet is 2-way entry only. Standard notch depth is typically 1.5 inches.
Chamfers
Angled cuts on the bottom leading edges of the pallet (and sometimes the top edges) that allow forklift tines to slide under the pallet more easily. Chamfers reduce edge damage during handling and are especially important for automated pallet dispensers and conveyor systems.
Lead Board
The outermost deck board on the entry side of the pallet. It takes the most abuse from forklift tines and is the first board to need replacement. On recycled pallets, lead boards are inspected first for cracks and splits.
Entry Types Explained
Entry type determines how a forklift can access the pallet. This has a direct impact on warehouse layout, truck loading patterns, and handling speed.
2-Way Entry
Forklift tines can only enter from the two open ends of the pallet (the sides without stringers blocking access). The fork operator must approach the pallet from the correct direction, which limits flexibility in tight warehouse aisles.
Characteristics
- Stringer pallets without notches
- Stronger in the stringer direction — better for heavy one-directional loads
- Less common today — mostly used in half-pallets and specialized industrial applications
- Not compatible with pallet jacks from the stringer side
4-Way Entry
Forklift tines can enter from all four sides. This is achieved either by using block construction (gaps between blocks on all sides) or by cutting notches into the stringers on a stringer pallet. 4-way entry is the standard for modern warehousing.
Characteristics
- Block pallets or notched stringer pallets
- Maximum flexibility for loading, unloading, and racking
- Required for most automated warehouse systems and AS/RS installations
- Compatible with both forklifts and pallet jacks from any direction
Construction Types
The two primary construction methods determine a pallet's strength, entry type, repairability, and cost. Knowing the difference helps you choose the right pallet for your operation.
Stringer Pallets
Stringer pallets use three parallel boards (called stringers) running the length of the pallet to support the deck boards. They are the most common pallet type in North America due to low cost and easy repairability.
Block Pallets
Block pallets use solid wood blocks (typically 9 blocks per pallet) to support the deck structure. Connector boards run between the blocks. This design is inherently 4-way entry and offers superior racking performance.
Weight vs Load Capacity
Pallet weight and load capacity are two different measurements. Understanding both prevents overloading, warehouse accidents, and shipping damage.
Pallet Weight (Tare Weight)
The weight of the empty pallet itself. A standard 48x40 stringer pallet weighs between 30 and 48 lbs depending on lumber thickness, moisture content, and whether it is new or recycled. Block pallets are heavier at 50 to 70 lbs. Tare weight matters for freight cost calculations — carriers charge by total weight, which includes the pallet.
Static Load Capacity
The maximum weight a pallet can support while sitting stationary on a flat surface (floor stacking). Static capacity is always the highest rating — typically 2 to 3 times the dynamic capacity. A standard GMA pallet has a static capacity of approximately 5,000 to 7,500 lbs.
Dynamic Load Capacity
The maximum weight a pallet can support while being moved by a forklift or pallet jack. Movement creates dynamic forces (acceleration, deceleration, turning) that stress the pallet. The standard GMA pallet is rated at 2,800 lbs dynamic capacity. This is the number you should use for everyday operations.
Racking Load Capacity
The maximum weight a pallet can support when placed on warehouse racking beams (supported at the edges only, with the center span unsupported). This is the most demanding scenario and yields the lowest capacity rating — typically 60% to 75% of the dynamic capacity. A standard GMA pallet has a racking capacity of approximately 2,000 to 2,500 lbs.
How to Measure a Pallet
Accurate pallet measurements are essential for ordering replacements, fitting racking, and maximizing trailer space. Follow these steps to measure any pallet correctly.
Measure the Length (Stringer Length)
Place your tape measure along the stringer — the long structural board that runs between the top and bottom deck boards. Measure from one end to the other. On a standard GMA pallet, this is 48 inches. The length is always the stringer dimension and is stated first when referencing pallet size (e.g., 48×40 means 48 inches long).
Measure the Width (Deck Board Length)
Measure across the deck boards from edge to edge, perpendicular to the stringers. On a GMA pallet, this is 40 inches. The width is the second number in the size designation. Measure at both ends to check for squareness — if the measurements differ by more than 1/4 inch, the pallet may be warped.
Measure the Height (Overall Thickness)
Stand the tape measure vertically from the floor to the top of the top deck boards. Standard pallets range from 5 inches to 6.5 inches. Height determines racking clearance and stacking limits. For accurate height, measure in the center of the pallet, not at the edge where boards may be warped.
Check Entry Type
Look at the pallet from each of the four sides. If you can see clear openings for forklift tines on all four sides, it is a 4-way pallet. If only two sides have openings, it is a 2-way pallet. On stringer pallets, look for notches cut into the bottom of the stringers — notches indicate partial 4-way entry.
Count the Deck Boards
Count the top and bottom deck boards. A standard GMA pallet has 7 top boards and 5 bottom boards. Fewer boards may indicate a lighter-duty pallet. Board count affects load distribution — more boards mean better support for small or irregularly shaped items.
Measure Board Thickness and Gaps
Use calipers or a tape measure to check deck board thickness (typically 5/8 inch to 3/4 inch) and the gaps between boards (typically 2.5 to 3.5 inches). Board thickness affects load capacity, and gap width determines whether small items can fall through.

Pallet Height Guide
Pallet height affects forklift clearance, racking compatibility, stacking limits, and container utilization. Most pallets fall into one of four height categories.
Used for air freight, retail display, and export shipping. Lightweight plastic or pressed-wood construction. Saves vertical space in containers.
The most common height for stringer-style pallets. Provides adequate fork clearance for standard forklifts and pallet jacks. Used in general warehousing.
Typical for block pallets and heavy-duty stringer pallets. Provides maximum fork clearance and additional structural depth for heavier loads.
Oversized or reinforced pallets for extremely heavy loads (machinery, concrete, steel). Extra height comes from larger stringers or stacked block construction.
Height and Racking
When calculating racking beam spacing, add the pallet height plus the cargo height plus a minimum 4-inch clearance for fire sprinkler regulations. For example, a 6-inch pallet with 48-inch cargo needs beam spacing of at least 58 inches. Check your local fire code — some jurisdictions require 6-inch clearance between the top of cargo and the bottom of the next racking beam.

Product Dimensions
Your product should fit within the pallet footprint without overhang. Overhang increases damage risk during transport and makes stacking unstable. Underhang (product smaller than the pallet) wastes space but is acceptable if racking and trailer utilization are not concerns.
Racking Compatibility
Check your warehouse racking specs. Most selective rack systems accommodate 48×40 pallets but custom racking may require different dimensions. Block pallets perform better in push-back and drive-in racking. Measure your beam spacing and depth before ordering pallets.
Truck Configuration
Standard 53' trailers fit two 48×40 pallets side by side (double-pinwheeled) for 20 pallets per load. Using non-standard sizes may reduce trailer utilization. Always calculate pallet count per trailer before committing to a non-standard size.
Industry Standards
Many industries have standard pallet sizes. Using the industry standard simplifies logistics and improves compatibility with trading partners. Deviating from the standard may cause receiving rejections, added handling costs, or pallet exchange problems.
Weight Distribution
Heavier products need pallets with more deck boards and thicker stringers. Concentrated point loads (like machinery feet) require full-deck or close-boarded pallets. Distribute weight evenly across the pallet surface to prevent board deflection and breakage.
Environmental Conditions
Outdoor storage, cold storage, and humid environments affect wood pallets differently. Moisture causes swelling and mold. Extreme cold can make wood brittle. For wet or cold environments, consider heat-treated hardwood pallets or plastic alternatives.
