Walk a receiving dock for an hour and you will see the same thing we see at every plant: a 48x40 pallet that does not quite fit the rack, a 42x42 paint pallet turned sideways to squeeze into a trailer, a block pallet from one pooler stacked on a stringer pallet from another. Pallet dimensions look like a solved problem. They are not. They are overlapping standards that each made sense for one industry, one country or one truck, and the mismatches between them are where product gets damaged, trailers run half empty and automated lines jam.
This guide is the reference we wish someone had handed us: the GMA 48x40 and where it came from, the six ISO 6780 footprints, the EPAL Euro pallet, the North American sizes that persist by industry, entry and height, trailer and container math, racking, load ratings, and when a custom footprint is worth the trouble. It ends where our own work starts: dimensional consistency, which decides your automation uptime more than the size itself.
Key Takeaways
- The standard pallet size in North America is the GMA 48x40: 29% of the 919 million new wood pallets built in the U.S. in 2021, used by 72% of facilities surveyed in 2025.
- ISO 6780 recognizes six pallet footprints, from the 1,016 x 1,219 mm North American pallet to the 800 x 1,200 mm Euro pallet.
- A 53-foot dry van holds 26 GMA pallets straight loaded, 28 pinwheeled or 30 turned, but with 42,000 to 45,000 lb of legal payload, dense freight weighs out first.
- Pallet weight capacity is three numbers: static, dynamic and racking. Racking is almost always the lowest, and it decides whether a pallet can go into open beams.
- Automation does not care which footprint you choose, only whether every pallet matches the last one. Wood varies 8 to 10%; APS recycled HDPE pallets hold under 1%.
The GMA 48x40 Standard Pallet Size
The standard pallet size in the United States is 48 inches long by 40 inches wide. It is called the GMA pallet after the Grocery Manufacturers Association, which standardized the footprint in the 1960s so grocery shippers, warehouses and retailers could share one platform. Pallet Enterprise's history notes that the detailed spec was developed in the 1970s around a heavy-duty 13/16 inch deck and 2x4 stringers, and that it eroded over the following decades as manufacturers trimmed lumber. Today a typical GMA pallet is a partial four-way stringer pallet with five four-inch interior boards and two six-inch exterior boards on top, and three fours and two sixes on the bottom.
Why 48 by 40? Because it divides a trailer well: two across and thirteen deep fill a 53-foot van with almost no wasted floor (the math is in the trailer chapter below), and the footprint wastes less of an ISO container floor than any other ISO size.
Two things about the GMA matter. First, it is a footprint, not a build: a new kiln-dried GMA, a Grade B recycled one with plugged stringers and a pooler's 48x40 block pallet share the footprint and behave very differently under load and on a conveyor. Second, its share is slipping. Virginia Tech put 48x40 at about 35% of new pallets in 2016 and 29% in 2021, and facility usage fell from 77% to 72% between 2022 and 2025.
The Six ISO 6780 Pallet Dimensions
ISO 6780:2003, Flat pallets for intercontinental materials handling: principal dimensions and tolerances, is the standard that lets a pallet built in Ohio, Rotterdam or Osaka be handled anywhere. It does not pick a winner. It recognizes six footprints, each grown out of a regional trucking, rail or retail convention, and specifies the tolerances around them. Here is the whole standard in one view.
| Millimeters (W x L) | Inches (W x L) | Wasted container floor | Where it is used |
|---|---|---|---|
| 1,016 x 1,219 | 40.00 x 48.00 | 3.7% | North America (the GMA) |
| 1,000 x 1,200 | 39.37 x 47.24 | 6.7% | Europe, Asia (the ISO or industrial pallet) |
| 1,165 x 1,165 | 45.9 x 45.9 | 8.1% | Australia |
| 1,067 x 1,067 | 42.00 x 42.00 | 11.5% | North America, Europe, Asia |
| 1,100 x 1,100 | 43.30 x 43.30 | 14% | Asia |
| 800 x 1,200 | 31.50 x 47.24 | 15.2% | Europe (the Euro pallet; fits many doorways) |
The third column explains a lot of global freight behavior. The North American 40x48 wastes 3.7% of a container floor; the Euro pallet wastes 15.2%, which is why European shippers pushed carriers toward pallet-wide containers (2.438 m inside instead of 2.348 m). The pallet you standardize on quietly sets your ocean freight efficiency for years.
Why It Matters
A global network rarely runs one footprint. The goal is not one size; it is knowing which sizes you run, in what proportion, and designing racks, conveyors and trailer plans around that list.
The Euro Pallet: EPAL and the 800 x 1,200 Footprint
The Euro pallet is a block pallet, not a stringer pallet. Nine blocks sit between the decks, giving a forklift or pallet jack true four-way entry. Its 800 mm width lets a loaded pallet pass through a standard European doorway and fit two abreast in a rail car. The European Pallet Association (EPAL) owns the specification and licenses manufacturers and repairers; a pallet that meets it carries the EPAL brand on its blocks and exchanges pallet for pallet inside the European pool.
| Specification | EPAL Euro pallet (EPAL 1) |
|---|---|
| Dimensions | 800 x 1,200 x 144 mm (31.5 x 47.24 x 5.67 in) |
| Weight | Approximately 25 kg (55 lb) |
| Safe working load | 1,500 kg (3,307 lb) |
| Stacking | Bottom pallet may carry up to 5,500 kg (12,125 lb) on a solid, even surface |
| Construction | 11 boards, 9 blocks, 78 nails |
| Phytosanitary | All new EPAL pallets heat treated to ISPM 15 since January 1, 2010 |
| In circulation | More than 650 million EPAL pallets worldwide |
EPAL also licenses an EPAL 3 at 1,000 x 1,200 x 144 mm (about 30 kg, 13 boards and 84 nails), the European version of the ISO industrial footprint. Ship into Europe on 48x40 pallets and expect them to be treated as non-standard: they will not exchange in the pool, and automated European warehouses can reject them at the inbound profile check for being 16 mm too wide and 19 mm too long. One cross-border point: every new wood EPAL pallet has been heat treated under ISPM 15 since 2010. Plastic pallets need no treatment. Ours are 100% recycled HDPE and ISPM 15 exempt, so there is no treatment, no fumigation and no stamp to inspect.
Common North American Pallet Sizes by Industry
North America never fully consolidated on the GMA. The industry's production rankings list roughly ten footprints that keep showing up, each tied to the product it was designed around: drums dictate 48x48 and 44x44, telecom reels and paint cans settled on 42x42, dairy crates stack on 40x40. The table below is the production ranking the industry still cites.
| Inches (W x L) | Millimeters | Production rank | Industries |
|---|---|---|---|
| 40 x 48 | 1,016 x 1,219 | 1 | Grocery, consumer goods, most general freight |
| 42 x 42 | 1,067 x 1,067 | 2 | Telecommunications, paint |
| 48 x 48 | 1,219 x 1,219 | 3 | Drums (four 55-gallon drums per pallet), chemicals |
| 48 x 40 | 1,219 x 1,016 | 3 (tie) | Military, cement (the GMA footprint, stringers on the 48 in side) |
| 48 x 42 | 1,219 x 1,067 | 5 | Chemical, beverage |
| 40 x 40 | 1,016 x 1,016 | 5 (tie) | Dairy |
| 48 x 45 | 1,219 x 1,143 | 7 | Automotive; also common in pharmaceutical distribution |
| 44 x 44 | 1,118 x 1,118 | 8 | Drums, chemical |
| 36 x 36 | 914 x 914 | 9 | Beverage, bottling |
| 48 x 36 | 1,219 x 914 | 10 | Beverage, roofing shingles, packaged paper |
Two trends are moving this list. Millwood, one of the largest U.S. pallet manufacturers, reported in 2026 that block pallets are growing fast in food and beverage because major retailers mandate them, and that pharmaceutical shippers buy almost exclusively new, kiln-dried 48x40 and 48x45 pallets. The Pallet Report 2025 found 34% of facilities now use 48x48 and 18% use 24x20 half pallets. The chemical industry is the outlier: it runs the metric CP pallet family (CP1 through CP9) alongside 48x48 and 44x44.
Entry, Height and Pallet Weight Capacity
Two-Way, Partial Four-Way and True Four-Way Entry
- Two-Way Entry A pallet with solid stringers can only be entered from the two ends. It is the cheapest to build.
- Partial Four-Way Entry The GMA notches its three stringers so forklift tines can also enter from the sides. Hand pallet jacks still cannot, because their wheels would land on the bottom boards.
- True Four-Way Entry Block pallets (the Euro pallet, CHEP and PECO pooled pallets, most molded plastic pallets) replace stringers with nine blocks, so forklifts and jacks enter from all four sides. CHEP notes its block pallet also allows free-span racking in either direction.
Pallet Height
Height is the dimension everyone forgets until a load will not clear a rack beam or a trailer door. A new GMA stringer pallet is about 6.5 inches tall and a recycled one about 5 inches, because worn deck boards are replaced with thinner stock. A Euro pallet is 144 mm, about 5.67 inches. Most molded plastic 48x40 and 48x48 pallets run 5 to 6 inches. That inch matters when double stacking in a 108 inch trailer or in a rack bay set up for a different height.
Static, Dynamic and Racking Load
Pallet weight capacity is three ratings, and a pallet sold on one number is being sold badly. Static capacity is the weight a pallet supports at rest on a flat floor, including loaded pallets stacked on it; it is always the highest. Dynamic capacity is what it carries while moving on forks, a jack or a conveyor; it is always lower. Racking capacity is the load it holds while bridging open beams with nothing under its center, and it is almost always the lowest. Every rating assumes an evenly distributed load. The test methods are ASTM D1185, whose static compression and bending tests estimate stiffness, strength and safe working loads, and its international counterpart, ISO 8611.
| Pallet | Static | Dynamic | Racking or free span | Source |
|---|---|---|---|---|
| New GMA 48x40 wood stringer (one supplier's spec) | 7,500 lb | 4,600 lb | 2,800 lb | Repackify, 2026 |
| CHEP 48x40 wood block (pooled) | Stack 5 high, max 10,000 lb | 2,800 lb design load | Free span either direction | CHEP |
| EPAL Euro pallet 800 x 1,200 | 5,500 kg on bottom pallet | 1,500 kg safe working load | Not rated by EPAL | EPAL |
| Rackable plastic 48x40 | Up to 30,000 lb or more | Varies by design | Rated, required for open beams | Container Exchanger, 2026 |
Watch Out
A used wood pallet carries none of these numbers with it. Ratings are for the design as built; a Grade B pallet with plugged stringers is a different structure, and nobody re-tests it. If your racks assume 2,800 lb per position on wood, that assumption is only as good as your inbound inspection.
Nestable, Stackable and Rackable Plastic Pallets
- Nestable Plastic Pallets Molded with legs instead of a bottom deck, so empties nest and cut empty storage and return freight by as much as 75%. Light and inexpensive, built for one-way distribution, not for racking.
- Stackable Plastic Pallets Have a bottom deck or runners so loaded pallets sit squarely on one another on the floor. Good static capacity, modest racking numbers.
- Rackable Plastic Pallets Reinforced, often with steel bars molded into the deck, to carry a load across open beams without sagging. The heaviest and most expensive type, and the only one that belongs in selective racking or an AS/RS.
How Pallet Footprints Fit Trailers, Containers and Racks
The 53-Foot Dry Van
A 53-foot dry van is about 636 inches long, 98 to 100 inches wide (100 is most common) and 108 to 110 inches high inside. Straight loaded, two GMA pallets fit across on their 40 inch side (80 of 100 inches) and thirteen down the length on their 48 inch side (624 of 636 inches): 2 x 13 = 26. Turned, two fit across on the 48 inch side (96 inches) and fifteen down the length on the 40 inch side (600 inches): 2 x 15 = 30. Pinwheeling, alternating orientations, lands at 28.
| Pallet footprint | Across (in) | Deep (rows) | Single-stacked pallets | Pattern |
|---|---|---|---|---|
| 48 x 40 GMA | 2 x 40 = 80 | 13 x 48 = 624 | 26 | Straight |
| 48 x 40 GMA | Mixed | Mixed | 28 | Pinwheel |
| 48 x 40 GMA | 2 x 48 = 96 | 15 x 40 = 600 | 30 | Turned |
| 48 x 48 drum | 2 x 48 = 96 | 13 x 48 = 624 | 26 | Straight |
| 42 x 42 | 2 x 42 = 84 | 15 x 42 = 630 | 30 | Straight |
| 48 x 42 | 2 x 42 = 84 | 13 x 48 = 624 | 26 | Straight |
Then weight takes over. Federal law caps a tractor-trailer at 80,000 lb gross, 20,000 lb on a single axle and 34,000 lb on a tandem, which leaves a typical dry van 42,000 to 45,000 lb of payload. Spread 44,000 lb over 26 pallets and each one, product plus platform, can weigh about 1,690 lb before the truck weighs out; for beverages, canned goods or chemicals that limit arrives first. Our HDPE pallets are up to 30% lighter than wood, about 2,200 lb less dead weight per truckload, which on a weight-limited lane is 2,200 lb more product per truck.
ISO Containers
A 20-foot container is about 5.90 m long by 2.35 m wide by 2.39 m high inside. A 40-foot is about 12.03 m long at the same width and height; the 40-foot high cube adds height to 2.69 m on the same floor. Width is the constraint: 2.35 m (92.5 inches) is narrower than a van, so two GMA pallets on their 48 inch side (96 inches) will not fit across, and the straight pattern falls back to two across on the 40 inch side.
| Container | Interior (L x W x H) | 48x40 GMA pallets | 1,200 x 1,000 industrial | 800 x 1,200 Euro |
|---|---|---|---|---|
| 20 ft standard | 5.90 x 2.35 x 2.39 m | About 10 | 9 to 10 | 11 |
| 40 ft standard | 12.03 x 2.35 x 2.39 m | 20, up to 21 optimized | 20 to 21 | 24 to 25 (iContainers); 23 (Haalboom) |
| 40 ft high cube | 12.03 x 2.35 x 2.69 m | Same floor as 40 ft | Same floor as 40 ft | Same floor as 40 ft |
| 40 ft pallet wide | Interior width 2.438 m | Not typical | Not typical | 30 |
A 40-foot container takes 20 or 21 GMA pallets while a 53-foot van takes 26 to 30, so a domestic load plan transloaded into containers leaves four to six orphan pallets at the port. If an export lane matters, plan the unit load around the container.
Pallet Racking
Selective pallet racking in North America is built for the GMA. Frames are most commonly 42 inches deep for 48 inch pallets, leaving three inches of overhang front and back so the pallet rests on the beams by its stringers or blocks; 48 inch deep frames serve 48x48 drum pallets. Beams come in 96 and 108 inch lengths to hold two 40 inch wide pallets; Uline's standard duty 108 inch beam, for example, is rated at 5,000 lb per pair, and the rack is built to the Rack Manufacturers Institute standard. A pallet racked across its 48 inch length is bridging a span, which is exactly the racking rating above, and a plastic pallet with no racking rating has no business on those beams.
Key Takeaway
Design the unit load from the outside in: container or trailer first, then rack bay, then pallet, then case pattern. Do it the other way around and you get a pallet that fits the product perfectly and wastes 15% of every box you ship it in.
When a Custom Pallet Footprint Makes Sense
Most of the time the right answer is the standard. A 48x40 moves through anyone's dock, any pooler supplies it, any rack holds it and any trailer plan assumes it. But the industries that run 48x45, 44x44 or a CP footprint did not pick them for fun; the product dictated the platform. Millwood describes building materials pallets as highly customized to the product, its use and its durability requirements, and that logic reaches well beyond lumber yards. Here is the framework we walk through with closed-loop partners.
- Does the Product Set the Footprint? Four 55-gallon drums are 48x48. A returnable automotive module is 48x45. If the product fixes the unit load, the pallet follows it and a GMA just wastes deck.
- Is the Loop Closed? A custom footprint only works if the pallets come back. In a one-way lane an odd size becomes waste at the receiver; in a closed loop between your own facilities it can be whatever the line needs.
- What Do the Trailer and Container Say? Run the math for the actual lane. A 45 inch deep pallet takes 14 rows in a 53-foot van instead of 13, and a 1,000 mm wide pallet fits two across in a container with room to spare.
- What Does the Automation Need? Ask the integrator for the pallet profile before you order pallets. AS/RS systems often require block construction, true four-way entry and tolerances of about a quarter inch.
- Who Else Has to Handle It? Retailers deduct for non-compliant pallets. If the end customer is a grocer, the footprint is 48x40 whether you like it or not; customize the build, not the size.
- What Does It Cost Over the Life of the Fleet? Custom wood means a custom mill run every time pallets break. Custom molded plastic means a mold, a fixed cost that pays off only across hundreds of trips per pallet, which is how a leased HDPE fleet that comes back is meant to run.
Custom footprints pay off exactly where closed-loop leasing pays off: regulated or high-value product, repeat lanes, automation at one or both ends, and a receiver who is part of the program. Those are the conditions under which APS designs pallet programs by industry.
Dimensional Consistency: The Spec That Automation Actually Reads
Here is the part of pallet dimensions no size chart captures. An automated line does not read a spec sheet; it reads the pallet in front of it. A conveyor photo-eye, an AS/RS shuttle and a robotic depalletizer were all calibrated to a footprint, a height and a flatness, and they expect every pallet to match. Wood does not. Lumber shrinks and swells with humidity, boards cup, stringers split and get plugged, and the fleet that was 48x40 on paper arrives at the induction station varying 8 to 10% in its dimensions. Millwood puts the threshold bluntly: a variance of even half an inch can cascade into system-wide failures.
The 2019 survey of 259 facilities, run with Virginia Tech, found that poor quality or missing bottom boards causing jams or faults was the most common pallet problem, with 53% of respondents dealing with it daily or weekly. By 2025, three quarters of respondents rated broken components as extremely important to their automated systems, and 63% said the same of protruding nails and of dimensional tolerances. We wrote about what that costs in The Pallet Is Costing You More Than You Think: the pallet sits in one budget while the jams, downtime and damage land in four others.
Where APS Fits
We should be plain about what we do and do not do. We do not make the GMA footprint better than anyone else; 48x40 is 48x40. What we do is make every pallet in a fleet the same pallet. APS Smart Pallets are molded from 100% recycled HDPE to tolerances under 1%, they do not absorb moisture or swell, there are no nails to protrude and no boards to go missing, and they hold their shape for roughly 100 to 200 or more trips instead of the 3 to 5 a white wood pallet manages. They match wood in load-bearing capacity; the material case is on our Why Plastic page.
Because the footprint and deck are consistent, the pallet can carry something else consistently too: an embedded sensor module with cellular GPS plus temperature, humidity and shock, reporting through our Pulse platform on an exception basis. A sensor built into the pallet, not bolted on, needs a pallet whose geometry does not change from trip to trip. The lease is all-inclusive, priced at or below what companies already pay for wood pallet programs. If you are weighing a footprint change, send us the lanes and the equipment list and an APS expert will come back with a program scoped to them.
Automation never asked for a better pallet size. It asked for the same pallet, every time.

FAQ
What Is the Standard Pallet Size in the United States?
The standard pallet size in the U.S. is 48 by 40 inches, the GMA pallet named for the Grocery Manufacturers Association that standardized it. Virginia Tech found it made up 29% of the 919 million new wood pallets produced in 2021, and 72% of facilities surveyed in 2025 use it. A new wood GMA pallet is about 6.5 inches tall and weighs roughly 30 to 48 pounds.
What Are the Dimensions of a Euro Pallet?
The EPAL Euro pallet (EPAL 1) measures 800 by 1,200 by 144 millimeters, about 31.5 by 47.24 by 5.67 inches, and weighs approximately 25 kilograms. It is a block pallet with true four-way entry, built from 11 boards, 9 blocks and 78 nails, rated for a 1,500 kilogram safe working load and up to 5,500 kilograms on the bottom pallet of a stack.
How Many Pallets Fit in a 53-Foot Trailer?
A 53-foot dry van with a 636 by 100 inch interior holds 26 GMA 48x40 pallets straight loaded in two rows of 13, 28 pinwheeled, or 30 turned sideways in two rows of 15. It holds 26 pallets at 48x48 and 30 at 42x42. Weight is usually the real limit: with 42,000 to 45,000 pounds of legal payload, 26 pallets can average only about 1,690 pounds each.
How Many Pallets Fit in a 40-Foot Container?
A standard 40-foot container, about 12.03 by 2.35 by 2.39 meters inside, holds 20 GMA 48x40 pallets on one tier, or 21 with an optimized pattern, per iContainers. The same floor takes 20 to 21 industrial 1,200 x 1,000 mm pallets and 23 to 25 Euro pallets depending on the guide; a pallet-wide box with a 2.438 meter interior takes 30 Euro pallets. A high cube adds height for double stacking, not floor positions.
What Is the Difference Between Nestable, Stackable and Rackable Plastic Pallets?
Nestable plastic pallets have legs instead of a bottom deck, so empties nest inside each other and save up to 75% of empty storage space; they are light, inexpensive and not meant for racking. Stackable pallets have a bottom deck or runners so loaded pallets sit squarely on one another. Rackable pallets are reinforced, often with steel bars molded into the deck, to carry a load across open beams; they are the only type that belongs in pallet racking or automated storage.
