Pallet size is the single most common source of confusion and chargeback in the supply chain. A supplier ships on the wrong size, the retail DC rejects the pallet, and a $25-75 per-pallet chargeback hits the account. The question "what size is a standard pallet?" has a simple answer -- 48 x 40 inches in the US -- but the full picture is more nuanced. International trade, specific industries, military procurement, and specialty retailers all have distinct pallet dimensions that affect shipping, racking, forklift compatibility, and compliance. This guide covers every standard pallet size used in 2026 with the context you need to choose correctly.

Pallet Lumber & Sawmill Operations
Stamped kiln-dried pallet lumber, bulk warehouse stock, dimensional yard inventory, raw softwood logs, and sawmill operations - the supply chain behind every custom and standard pallet we ship.
The 48 x 40 inch (1,219 x 1,016 mm) pallet is the dominant standard in the United States. It was standardized by the Grocery Manufacturers Association (GMA, now the Consumer Brands Association) decades ago and has been adopted by virtually every major US retailer, distributor, and manufacturer as the default unit of commerce. Over 90% of all pallets in US domestic circulation are GMA 48x40.
The GMA pallet is a stringer-style pallet (three parallel 2x4 stringers running the 48-inch length) in its most common form, though 48x40 block pallets also exist. Key specifications:
- Dimensions: 48 inches long x 40 inches wide x 5.5 inches tall (standard stringer)
- Weight: 35-50 lbs empty (heavier for block style or hardwood)
- Dynamic capacity: 2,800 lbs (standard stringer, new or Grade A)
- Static capacity: Up to 30,000 lbs (floor storage, distributed load)
- Forklift entry: 2-way (standard stringer) or 4-way (block, or notched stringer)
- Truck fit: 26 pallets per 53-foot dry van trailer (2 rows of 13); up to 30 with pinwheel loading

GMA Size Variants: When 48x40 Is Not the Right Choice
Best for cylindrical containers (drums, barrels, paint cans) that need maximum base support. Common in chemical, paint, and industrial gas industries. Does not fit standard GMA racking without modification.
Standard in the telecommunications equipment and paint industries. Telecom DCs are built around 42x42 pallet bays. Paint manufacturing lines use 42x42 to fit paint can configurations (4x4 or 5x5 case layouts).
Smaller footprint fits in dairy cooler configurations and certain produce packinghouse conveyors. Common in the US dairy industry for milk crates and in specialty produce operations with tight cooler aisles.
Soft drink, water, and beer cases often configure better on 48x42 for case count optimization. Some beverage bottlers have maintained this non-standard size for decades in their proprietary distribution systems.
The US Department of Defense uses 48x45 pallets per MIL-STD-1660. Defense contractors and government suppliers must match this spec for military procurement. DoD also uses 463L air cargo pallets (88x108 inches) for air transport.
Automotive OEM suppliers, aerospace manufacturers, and specialty agricultural operations often require custom pallet sizes matching their specific process or product footprint. We manufacture custom pallets with typical lead time 5-10 business days.
ISO International Pallet Standards
The International Organization for Standardization (ISO) defines six official pallet sizes under ISO 6780:2003. These are the globally recognized standard sizes -- important for operations involved in international import/export:
| ISO Designation | Dimensions (mm) | Dimensions (inches) | Primary Region |
|---|---|---|---|
| ISO 1 | 1000 x 1200 | 39.4 x 47.2 | Europe, Asia |
| ISO 2 | 800 x 1200 | 31.5 x 47.2 | Europe (EUR-1) |
| ISO 3 | 1000 x 1200 | 39.4 x 47.2 | Australia, Asia |
| ISO 4 | 800 x 1200 | 31.5 x 47.2 | Europe |
| ISO 5 | 1219 x 1016 | 48 x 40 | North America (GMA) |
| ISO 6 | 1067 x 1067 | 42 x 42 | North America |
The GMA 48x40 is ISO 5 -- an internationally recognized standard, though rarely called "ISO 5" in US domestic operations.
Forklift Entry Compatibility by Pallet Size
Pallet size affects which sides a forklift can enter, which in turn affects warehouse flow, racking orientation, and conveyor compatibility:
| Pallet Size | Forklift Entry | Racking Orientation | Conveyor Compatible? |
|---|---|---|---|
| 48x40 Stringer (standard) | 2-way (40-inch sides only) | 48 facing aisle OR 40 facing aisle | Yes (most conveyors) |
| 48x40 Block | 4-way (all sides) | Either orientation | Yes |
| 48x40 Notched Stringer | 4-way (notched for partial entry) | Either orientation with caution | Yes |
| 48x48 | 4-way (square, all sides equal) | Any orientation | May require conveyor adjustment |
| 42x42 | 4-way | Any orientation | Not standard; requires adjustment |
| Euro 800x1200 | 4-way (Euro block construction) | 800mm or 1200mm facing aisle | Requires metric conveyor |
How Many Pallets Fit in a Truck by Size?
| Truck Type | 48x40 GMA | 48x48 | Euro 800x1200 |
|---|---|---|---|
| 53-foot dry van (standard) | 26 pallets (2 rows) | 21 pallets | 33 pallets (metric loading) |
| 53-foot dry van (pinwheel) | 30 pallets | N/A | N/A |
| 48-foot trailer | 24 pallets | 19 pallets | 30 pallets |
| 20-foot ocean container | 11 pallets | 9 pallets | 11 pallets (ISO 1) |

Custom Pallet Sizes: When Standard Won't Work
Some operations genuinely need non-standard pallet sizes. Valid reasons to order custom pallets include:
- Automotive OEM specs: Kia, Hyundai, BMW, and Toyota each have proprietary pallet specifications for certain components. These are non-negotiable for Tier 1/2 suppliers.
- Aerospace and defense: Aircraft components, satellite assemblies, and defense electronics often have non-standard footprints requiring custom pallets.
- Florida citrus: Field bins and citrus packinghouse pallets often run 48x24, 36x36, or 48x48 depending on the grower and packinghouse configuration.
- Nursery and horticulture: Rack-style nursery pallets used in plant production greenhouses are almost always custom-built to match greenhouse bay spacing.
- Oil and gas: Pipe, tubing, and drilling equipment require custom pallet lengths ranging from 60 to 120 inches.
We manufacture custom pallets to spec with standard lead time of 5-10 business days for most sizes. Contact us with dimensions, load requirements, and forklift entry needs for a quote.
Frequently Asked Questions
The standard pallet size in the United States is 48 x 40 inches (1,219 x 1,016 mm), known as the GMA pallet (after the Grocery Manufacturers Association, now Consumer Brands Association). Over 90% of all pallets in US domestic circulation are 48x40. All major US retailers -- Walmart, Amazon, Target, Kroger, Publix, Costco, and Whole Foods -- require 48x40 GMA pallets for inbound shipments.
The most common Euro pallet (EUR-1 or EUR/EPAL) measures 800 x 1,200 mm, which converts to approximately 31.5 x 47.2 inches. This is significantly narrower than the US GMA standard (40 inches wide vs 31.5 inches). Euro pallets are the standard in the European Union and often arrive in the US on import shipments -- they are not compatible with US standard racking without modification and typically need to be transloaded to GMA 48x40 pallets for domestic distribution.
A GMA 48x40 pallet is 40 inches (1,016 mm) wide, while the standard Euro pallet (EUR-1) is 31.5 inches (800 mm) wide -- making the GMA pallet 8.5 inches (216 mm) wider. This width difference matters for racking (Euro pallets can fall between GMA-spaced rack beams), conveyor systems, and truck loading configuration. If you receive Euro pallets on import shipments, transload to GMA 48x40 before entering your domestic distribution racking system.
Walmart requires GMA standard 48x40 inch pallets for all inbound supplier shipments. The pallet must be Grade A (near-new condition), GMA stringer or block construction, free of broken boards, split stringers, protruding nails, chemical contamination, and pest evidence. Non-compliant pallets trigger chargebacks of $15-75 per pallet per Walmart's Vendor Compliance Guide. Same requirement applies to Sam's Club, though some Sam's Club warehouse floor display items may use 48x48 display pallets for specific configurations.
