How Many Pallets Fit in a Full Truckload? Capacity Planning Made Simple

Every shipper reaches the same crossroads sooner or later. You have freight sitting on pallets and need to decide whether to book a full truckload or split the shipment across a shared trailer. The answer starts with one number: how many pallets in a full truckload your trailer can actually hold.

For a standard 53-foot dry van loaded with 48 x 40 inch GMA pallets, the baseline is 26 pallets in a single layer. That figure changes with trailer type, stacking ability, cargo weight, and the commodity on the pallet. Get the count wrong and you either overpay for empty space or scramble to find room for leftover freight.

This guide breaks down real pallet counts for every common trailer, explains the factors that reduce those theoretical maximums, and shows when a partial truckload or LTL shipment is the smarter move.

Standard pallet counts by trailer type

The 48 x 40 inch pallet, known in the industry as the GMA pallet after the Grocery Manufacturers Association, is the most common size in North American shipping. Two of these pallets fit side by side in most trailers because the interior width of a standard trailer is roughly 100 inches.

Here is what each trailer type holds when loaded with standard GMA pallets in a single layer.

53-foot dry van

A 53-foot dry van is the workhorse of full truckload shipping. Its interior measures approximately 53 feet long, 100 inches wide, and 110 inches tall. You can place 13 rows of two pallets side by side, giving you 26 pallets on one level. If your cargo can be double-stacked safely, the count jumps to 52.

Some shippers use a technique called pinwheeling, where alternating pallets are rotated 90 degrees. This can squeeze in up to 28 pallets on a single layer. Most warehouses lack the forklift setup to handle pinwheeled loads efficiently, so 26 remains the practical standard.

53-foot reefer trailer

Refrigerated trailers carry insulation and cooling units that eat into the usable interior. Wall thickness reduces the width by a few inches, and the ceiling-mounted refrigeration unit lowers the load height. Expect 22 to 24 standard pallets in a single layer, depending on the manufacturer of the reefer unit.

Double stacking in a reefer is possible but less common. Temperature-sensitive goods like produce, dairy, and frozen foods often cannot bear the compression of a second pallet on top.

53-foot flatbed trailer

A flatbed offers the same deck length as a dry van, so 26 single-stacked pallets fit in a standard side-by-side arrangement. The difference is height. Without an enclosed ceiling, flatbed cargo can ride taller, limited only by the federal maximum vehicle height of 13 feet 6 inches. A standard flatbed deck sits about 5 feet off the ground, leaving roughly 8 feet 6 inches for cargo.

Flatbeds work well for building materials, heavy machinery, and oversized items that would not fit through a dry van's rear doors. Tarping is required for weather protection, and that adds cost and loading time.

48-foot trailer

Shorter 48-foot trailers are less common but still used in certain regional lanes. These hold 24 standard pallets in a single layer and 48 when double-stacked. The 5-foot difference in length removes one full row of two pallets compared to the 53-foot trailer.

Why your real pallet count is often lower

The numbers above represent theoretical maximums. In daily operations, most shippers load fewer pallets than the trailer can technically hold. Several factors cut into that total.

Weight limits

Federal law caps the gross vehicle weight of a loaded tractor-trailer at 80,000 pounds. The tractor and empty trailer together weigh roughly 30,000 to 35,000 pounds, leaving 45,000 to 50,000 pounds for cargo. If each pallet weighs 2,000 pounds, you hit the weight ceiling at around 22 pallets, well short of the 26 you have floor space for.

Dense commodities like beverages, canned goods, paper products, and metal parts often "weigh out" a trailer before they "cube out." Always calculate total load weight before you plan pallet positions.

Pallet height and stacking restrictions

Double stacking doubles your count, but only if two conditions are met. First, each pallet must be short enough that two of them fit within the trailer's interior height. For a dry van with 110 inches of clearance, each pallet needs to stay under 55 inches tall. Second, the product on the bottom pallet must be strong enough to support the weight above it without crushing or shifting.

Fragile goods, irregularly shaped packages, and anything with a high center of gravity are poor candidates for stacking. Forcing a double stack on weak freight leads to product damage, rejected deliveries, and insurance claims.

Commodity type and packaging

Not all pallets are identical. Oversized boxes, drums, and odd-shaped items create air gaps that waste space. A pallet of uniform cartons stacks tight and clean. A pallet of mixed-size boxes leaves voids.

Hazardous materials add another constraint. HAZMAT shipments require specific placarding, segregation from incompatible goods, and sometimes reduced loading density to meet Department of Transportation regulations.

Loading configuration

Straight loading, where every pallet faces the same direction, is the fastest to load and unload. Turned loading and pinwheeling can add one or two extra pallets, but they require more time at the dock and wider forklift clearance. The cost of extra dock time may outweigh the savings from that one additional pallet.

How to calculate your actual load plan

A simple three-step process helps you plan before you call for a quote.

Step one: count your pallets and measure the dimensions of each one. Length, width, and height all matter.

Step two: add up the total weight. Include the weight of the pallet itself, which is usually 30 to 45 pounds for a standard wooden GMA pallet.

Step three: compare your total weight against the trailer's cargo limit (roughly 44,000 to 45,000 pounds for a dry van) and your total pallet count against the trailer's floor capacity.

If either weight or count exceeds the trailer's limit, you need a second truck or a different trailer type.

When partial truckload beats a full truck

Not every shipment needs a full trailer. If you are shipping fewer than 20 pallets, paying for 26 pallet positions worth of space wastes money. That gap between a small FTL and a large LTL shipment is where partial truckload, sometimes called volume LTL, fills in.

The partial truckload sweet spot

Partial truckload generally works best for 6 to 18 pallets weighing between 5,000 and 25,000 pounds. Your freight shares the trailer with one or two other shipments heading in the same direction. You pay only for the space you use, not the full truck.

Unlike standard LTL, partial truckload shipments go through fewer handling points. Your pallets stay on the same trailer from pickup to delivery in most cases, reducing the risk of damage.

LTL for smaller loads

Standard LTL shipping covers shipments of 1 to 6 pallets that weigh under 10,000 pounds. Carriers consolidate multiple shippers' freight onto one trailer and route it through a hub-and-spoke network. Transit times are longer because the trailer makes multiple stops, but the per-pallet cost is significantly lower than booking an entire truck.

LTL pricing is based on freight class, weight, distance, and dimensions. The National Motor Freight Traffic Association publishes the classification system that LTL carriers use to set rates.

Choosing between FTL, partial, and LTL

Here is a general guideline for matching your shipment to the right mode.

For 1 to 6 pallets under 10,000 pounds, standard LTL is usually the most economical choice. For 6 to 18 pallets between 5,000 and 25,000 pounds, partial truckload or volume LTL offers a balance of cost and speed. For 18 or more pallets, or shipments over 20,000 pounds, a full truckload typically gives you the best per-unit cost and fastest transit.

These thresholds shift based on distance, lane density, and freight class. A 12-pallet shipment of lightweight foam products might move cheaper as partial truckload, while 12 pallets of bottled water might pencil out better as FTL.

Pallet loading tips that protect your freight and your budget

Good load planning goes beyond counting pallets. How you arrange freight inside the trailer affects safety, compliance, and cost.

Distribute weight evenly across the trailer floor to keep axle loads within legal limits. Heavy pallets belong near the center of the trailer, between the drive axles and the rear axles. Uneven weight distribution causes tire blowouts, brake wear, and DOT violations at weigh stations.

Secure every pallet with load bars, straps, or dunnage. A pallet that shifts during transit can topple into adjacent freight and cause thousands of dollars in damage.

Load the tallest pallets first, against the front wall of the trailer. Fill in with shorter pallets behind them. This creates a stable block of freight that resists forward momentum during braking.

If you ship temperature-sensitive products, verify that airflow channels remain open inside the reefer. Blocking the refrigeration unit's air circulation creates hot spots that spoil cargo.

Plan your next shipment with the right pallet count

Knowing how many pallets fit in a full truckload is the starting point for every freight decision. A 53-foot dry van holds 26 standard pallets on one level, a reefer holds 22 to 24, and a flatbed holds 26. Weight limits, stacking ability, and commodity type determine whether you reach those ceilings.

If your load falls short of a full trailer, partial truckload and LTL options keep you from paying for empty air. If it fills or exceeds a single truck, your planning now includes whether to split across two trailers or consolidate into one efficient load.
