48x40 Pallets in Los Angeles: The Standard GMA Size Explained

When someone asks for a standard pallet without giving a size, they almost always mean a 48x40. It is the footprint the North American supply chain quietly settled on decades ago, and most of the warehouses, trailers, and racking systems around Los Angeles are built around it. If you are buying pallets for the first time, or trying to figure out which size your freight actually needs, the 48x40 is the baseline everything else is measured against.

The 48x40 earned its default status for concrete reasons, and those same reasons are what tell you when it is the right pallet and when it is not. That covers the dimension itself, what one weighs and holds, the grades it comes in, and the question most LA businesses end up asking us, which is where to buy them and whether you can get them for free. We stock 48x40 pallets in every grade at our yard in Los Angeles, so these are the numbers we work with daily.

What a 48x40 Pallet Actually Is

A 48x40 pallet measures 48 inches on one side and 40 inches on the other, written width by depth in the way the industry always lists pallet sizes. That single footprint is the most common pallet in North America and accounts for roughly 30 percent of all new wood pallets produced each year. It is often called a GMA pallet, after the Grocery Manufacturers Association that helped standardize it, and the two terms point to the same thing.

The reason the size matters so much is that it is not arbitrary. Two 48x40 pallets sit side by side across the width of a standard 53-foot trailer with almost no wasted space, which works out to around 26 pallets in a single ground layer. The same footprint drops cleanly into standard warehouse racking and is handled without fuss by every forklift and pallet jack on the floor. When a retailer like a grocery chain or a big-box store specifies a pallet, this is usually the one they mean. For the full range of footprints and how each fits a trailer, our pallet dimensions and size chart lays them out side by side.

GMA, Block and Stringer: Same Size, Different Build

A 48x40 footprint can be built two ways, and the distinction matters more than the size does once you are moving real weight. A stringer pallet uses long boards, the stringers, running between the top and bottom decks. A block pallet uses solid wood blocks, nine of them in a three-by-three pattern, which gives true four-way forklift entry from any side and a more rigid platform. Most of the 48x40 stock we sell are standard block pallets for exactly that reason. The deeper comparison lives in our breakdown of what a GMA pallet is.

What a 48x40 Pallet Weighs and Holds

An empty 48x40 wood pallet weighs roughly 33 to 48 lbs. Where it lands in that range comes down to the grade, the thickness of the lumber, the wood species, and how much moisture the boards are carrying, which is why a damp recycled pallet weighs more than a dry new one of the same size. That tare weight travels with your freight and shows up on the bill of lading, so it is worth knowing rather than guessing, as we explain in our guide to how much a pallet weighs.

Capacity is the separate figure people often confuse with weight. A standard 48x40 wood pallet carries a static load of roughly 2,500 to 4,600 lbs depending on grade, with a dynamic working limit around 2,500 lbs while it is being moved. That covers the great majority of palletized freight moving through LA. If your load runs heavier than that, or the shape does not fit a 40-inch depth, a 48x40 is the wrong tool and a reinforced or oversized build is the right one.

The 48x40 Grades and What They Are For

The same 48x40 pallet comes in different grades, and matching the grade to the job is where most of the savings are. We inspect and sort every pallet before it leaves the yard, so the grade you order is the grade you get.

• Grade A (Premium): Like-new condition, no broken or missing boards, all blocks intact. Used for retail display, export shipments, and the major retailers that require clean stock.
• Grade B (Standard): Structurally sound with minor cosmetic wear. The best balance of quality and value for general warehousing, internal transfers, and routine shipping.
• Grade C (Economy): Functional with visible wear and repaired boards. Suited to one-way shipments and light-duty use where cost is the priority.
• New: Built fresh when presentation or a guaranteed spec matters, and available heat treated for international export.

Where to Buy or Find Free 48x40 Pallets in Los Angeles

This is the question that brings most people to the topic in the first place. The honest answer has two halves, because a free 48x40 pallet and a reliable supply of 48x40 pallets are not the same thing.

If you need one or two pallets for a personal project, free is realistic. Plenty of LA businesses set used pallets out for collection, and our walkthrough of where to find free pallets in Los Angeles covers how to do it safely, including how to read the stamps so you avoid chemically treated wood. The catch is that free stock is unsorted, inconsistent, and never available in the quantity or grade a business actually runs on.

If you need 48x40 pallets for a business, by the dozen or by the thousand, that is a supply question rather than a scavenging one. We keep 48x40 pallets for sale in Los Angeles in every grade, sorted and ready, with free delivery on orders of 100 or more anywhere in our service area. You can see the current lineup and request specific grades or heat-treated stock through our free pallet quote and product page. Whether you need 50 or 5,000, the point of buying rather than collecting is that the size, grade, and count are exactly what you ordered.
