Almost every freight quote starts with the same question: how many pallets? The answer drives the price, the equipment and whether the shipment moves as LTL, partial or full truckload. Yet pallet counts are one of the most common sources of error in shipping. A load booked as 24 pallets turns out to need 28 positions, or the freight will not double stack, and the plan falls apart at the dock.
This guide covers the basics every shipper should know: standard pallet sizes, how many fit in common equipment, and the limits that matter more than floor space.
The standard pallet
In North America the most common pallet measures 48 inches by 40 inches. It is often called a GMA pallet, after the grocery industry association that standardized it. When a carrier or warehouse says “standard pallet” with no other detail, this is what they mean.
Other sizes are in regular use:
- 42 x 42 and 48 x 48 inches. Common for drums, paint, chemicals and bulk bags.
- 48 x 42 inches. Seen in chemical and beverage supply chains.
- Metric pallets. Imported goods frequently arrive on 1200 x 800 mm or 1200 x 1000 mm pallets, which do not fit a trailer the same way as a 48 x 40.
If your freight is on anything other than a 48 x 40, say so when you request a quote. Give the actual length, width and height of each loaded pallet, not the size of the empty pallet underneath.
How many pallets fit in a 53-foot trailer
A standard 53-foot dry van has roughly 52 feet 6 inches of usable interior length and about 8 feet 2 inches or more of interior width, with small differences between manufacturers.
With 48 x 40 pallets, the usual numbers are:
- 26 pallets loaded straight, two across, with the 48-inch side running the length of the trailer. Thirteen rows of two.
- Up to 30 pallets when some or all are turned so the 40-inch side runs the length of the trailer. Turned pallets are a tight fit side to side and only work if the freight does not hang over the pallet edge.
Those are single-layer floor counts. If the freight can be double stacked, the count can double, subject to height and weight. A 48-foot trailer holds 24 standard pallets loaded straight.
Refrigerated trailers have thicker insulated walls and a cooling unit, so their interior dimensions and capacity are somewhat smaller. See dry van vs. reefer for the differences.
How many fit in an ocean container
Ocean containers are narrower inside than a domestic trailer, about 7 feet 8 inches, which changes the arithmetic. Typical floor counts for 48 x 40 pallets are:
- 20-foot container: about 10 pallets
- 40-foot container: about 20 to 21 pallets
The exact figure depends on the loading pattern and on overhang. This difference is why a full 40-foot container usually transloads comfortably into a 53-foot trailer with room to spare, a practice explained in transloading vs. cross-docking.
Height: the limit people forget
Interior height in a standard dry van is around 110 inches, and the door opening is a little lower than the inside of the trailer. Two pallets at 54 inches each will not double stack, because the load has to clear the door frame and leave room to maneuver.
A common rule of thumb is to keep each pallet at or under about 48 inches tall if you want it double stacked. For LTL, pallets taller than a certain height are often treated as non-stackable and may be priced accordingly. Many LTL carriers also apply rules based on how much linear trailer space a shipment uses, which is part of why volume LTL and partial truckload exist as separate options.
Weight: the limit that actually stops trucks
Floor space is not the only constraint. On U.S. interstate highways the general gross vehicle weight limit is 80,000 pounds for a five-axle tractor-trailer. After subtracting the weight of the tractor and trailer, the cargo capacity of a dry van is typically somewhere around 43,000 to 45,000 pounds, depending on the equipment.
That means dense freight “weighs out” before it “cubes out.” Twenty-six pallets at 2,000 pounds each is 52,000 pounds, which is too heavy even though the floor is not stacked. Weight also has to be distributed across the axles, so a legal total can still be an illegal load if too much sits at one end.
Ocean containers add another wrinkle. A container can be loaded overseas to a weight that is fine for the ship and too heavy for the road. Heavy containers may need special chassis or permits.
Stackable or not
Whether pallets can be stacked is one of the most valuable facts you can give a carrier. Freight is generally stackable when:
- The top surface is flat and level.
- The cartons can bear the weight above without crushing.
- The load is stable and wrapped.
- The combined height fits the equipment.
If freight must not be stacked, mark it clearly and declare it on the bill of lading. Cones or “do not stack” labels help, but they are not a guarantee, particularly in LTL where freight is handled several times. Sturdy packaging is the real protection.
Building a good pallet
- No overhang. Cartons should sit inside the pallet edge. Overhang gets crushed and prevents tight loading.
- Heavy on the bottom. Put the heaviest cartons low and keep the stack square.
- Interlock when possible. Alternating carton patterns add stability, though column stacking is stronger for cartons that carry weight on their corners.
- Wrap it to the pallet. Stretch wrap should tie the load to the pallet itself, not just bundle the cartons.
- Use a sound pallet. Broken boards fail under a forklift.
- Label two sides. Make each pallet identifiable without moving it.

What to tell your carrier
An accurate quote needs five things for each group of pallets:
- Number of pallets
- Length, width and height of each, measured loaded
- Weight of each, including the pallet
- Whether they can be stacked
- What the product is
Measure, do not estimate. Carriers re-weigh and re-measure freight, and corrections after the fact cost more than accurate numbers up front.
The quick reference
- Standard pallet: 48 x 40 inches
- 53-foot trailer: 26 pallets straight, up to 30 turned, single layer
- 48-foot trailer: 24 pallets straight
- 40-foot container: about 20 to 21
- 20-foot container: about 10
- Typical dry van cargo weight: roughly 43,000 to 45,000 pounds
Treat these as planning figures. Your carrier’s equipment and your actual freight dimensions are what decide the final count.
