Standard Pallet Sizes and Shipping Preparation Guide

Pallets are the foundation of freight shipping. The pallet you choose affects your freight class, how efficiently your products fill a trailer, how safely they travel, and how much you pay per shipment. This guide covers every standard pallet size, their ideal uses, and the preparation steps that prevent damage, reclassification, and delivery rejection.

The GMA Standard: 48 x 40 Inches

The Grocery Manufacturers Association (GMA) pallet — 48 inches long by 40 inches wide — is the most widely used pallet in North America. It accounts for approximately 30% of all new pallets produced and is the default standard for LTL carriers, FTL operations, and most retail and grocery distribution centers.

GMA pallets feature 4-way entry (forklifts can access from all four sides), a typical tare weight of 33 to 48 pounds for wood pallets, and a dynamic load capacity of 2,500 to 2,800 pounds for standard-grade pallets. The 48 x 40 dimension was specifically chosen because two pallets placed side by side fit perfectly across the 96-inch interior width of a standard 53-foot trailer with minimal wasted space.

If you are shipping to Amazon FBA, major retailers, or grocery chains, GMA pallets are almost always required. See our Amazon FBA shipping guide for Amazon-specific pallet requirements.

Other Standard Pallet Sizes

While the GMA pallet dominates, several other sizes are standard in specific industries:

• 42 x 42 inches: Standard for the paint and coatings industry. The square shape accommodates round pails and drums efficiently.
• 48 x 48 inches: Used in the barrel and drum industry and common for chemical and beverage shipping. The extra 8 inches of width versus GMA pallets means they do not optimize trailer width as well, but they accommodate larger or square products better.
• 48 x 42 inches: Standard for the chemical and beverage industries. Slightly wider than GMA, optimized for specific product dimensions.
• 48 x 45 inches: Automotive industry standard. Designed for parts bins and component packaging used in automotive manufacturing supply chains.
• 44 x 44 inches: Common in the chemical and cement industries for drum and bag shipping.
• 36 x 36 inches: Used for smaller, denser shipments — particularly beverages, canned goods, and some industrial components. Their compact size makes them useful for retail end-cap displays.

EUR and International Pallets

If you import or export freight internationally, you will encounter European pallet standards. The most common are:

• EUR 1 (800 x 1200 mm / ~31.5 x 47.2 inches): The most widely used European pallet, managed by EPAL. It does not optimize US trailer widths, so companies importing on EUR pallets often transload to GMA pallets upon arrival for domestic distribution.
• EUR 2 (1000 x 1200 mm / ~39.4 x 47.2 inches): Used for larger or heavier European freight. Closer in dimensions to the GMA pallet but still requires width consideration in US trailers.
• EUR 6 (600 x 800 mm / ~23.6 x 31.5 inches): A half-pallet commonly used for retail display and smaller shipments. Two EUR 6 pallets equal one EUR 1 footprint.

For cross-border shipping between the US, Canada, and Mexico, GMA pallets are standard. ISPM-15 (International Standards for Phytosanitary Measures) requires all wood packaging material — including pallets — to be heat-treated or fumigated and stamped with the ISPM-15 mark for international shipments.

Pallet Materials

Wood remains the dominant pallet material in freight shipping, but alternatives exist for specific applications:

• Wood (stringer or block): The industry standard. Inexpensive, repairable, recyclable, and widely available. Stringer pallets use 2x4 or 3x4 stringers for support and typically offer 2-way forklift entry. Block pallets use blocks at the corners and center for 4-way entry and greater load capacity.
• Plastic: More durable, lighter, and easier to sanitize than wood. Required by some food and pharmaceutical companies for hygiene reasons. More expensive upfront ($15-$70 per pallet vs. $5-$20 for wood) but longer-lasting in closed-loop systems.
• Metal (steel or aluminum): Used for extremely heavy loads, high-temperature environments, and permanent warehouse storage systems. Rarely used in one-way freight shipping due to cost and weight.
• Corrugated and presswood: Lightweight, inexpensive, and exempt from ISPM-15 requirements for international shipping. Lower load capacity limits them to lighter freight.

How Pallet Choice Affects Freight Class

For LTL shipments, your freight class is determined partly by density — pounds per cubic foot. The pallet you choose directly affects the cubic dimensions of your shipment. A taller pallet with fewer products per layer takes up more cubic space for the same weight, resulting in a lower density and potentially a higher freight class.

To optimize freight class and minimize LTL costs: use the smallest pallet that safely accommodates your product, stack as high as safely possible (most carriers accept up to 72 inches total height including the pallet), and arrange products to minimize void space. Denser stacking means a lower freight class and a lower rate per hundredweight. For more on how freight class affects pricing, see our complete freight shipping cost guide.

Stacking and Shrink-Wrapping Best Practices

Proper stacking and wrapping prevent damage, reduce claims, and ensure your freight arrives in the same condition it left your dock:

• Brick-lay stacking pattern: Alternate the direction of boxes on each layer so they interlock, creating a more stable stack. Column stacking (all boxes in the same orientation every layer) is weaker and more prone to shifting.
• Do not overhang the pallet: Products should not extend beyond the pallet edges. Overhanging freight gets damaged by forklift tines, adjacent pallets, and trailer walls.
• Shrink wrap to the pallet: Wrap from the top of the stack down to the pallet deck, catching the top deck boards in the wrap. This anchors the load to the pallet and prevents the stack from sliding off during transport.
• Use corner boards: Cardboard or plastic corner protectors placed at the vertical edges before wrapping add structural rigidity and prevent strap or wrap damage to product packaging.
• Top sheets or caps: A flat cardboard or plastic cap on top of the stack, under the shrink wrap, distributes pressure if pallets are double-stacked in transit.
• Weight distribution: Place heavier items on the bottom and lighter items on top. Center the weight over the pallet to prevent tipping during forklift handling.

Trailer Loading and Pallet Optimization

A standard 53-foot trailer has an interior length of approximately 636 inches and an interior width of 98.5 inches. Two GMA pallets (each 48 inches long) placed side by side span 80 inches — fitting within the 98.5-inch width with room for a forklift to maneuver. Placed lengthwise (40-inch dimension along the trailer length), you can fit approximately 15 rows of 2 pallets, for a total of 30 pallets on a single layer.

If your freight allows double-stacking (the bottom pallet can support the weight of a second pallet on top), you could fit up to 60 pallets per trailer — though this depends entirely on the weight capacity of the trailer (typically 44,000 to 45,000 pounds of freight) and the stackability of your product.

Pallet Inspection Before Shipping

Before loading freight onto a pallet, inspect it for these common defects that cause damage and claims:

• Broken or missing deck boards (products can fall through)
• Cracked or split stringers/blocks (pallet may collapse under weight)
• Protruding nails (puncture risk for products and worker safety hazard)
• Excessive moisture or mold (contaminates products, especially food)
• Chemical stains or odors from prior use (contamination risk)
• Warped or twisted frame (pallet will not stack or sit flat on the trailer floor)

Rejecting a bad pallet before loading is far cheaper than filing a freight claim after delivery. If you need help optimizing your pallet strategy and freight preparation, contact our team for a consultation.
