Standard Pallet Size: 48" x 40" (GMA Pallet)
The most common pallet in the U.S. is the 48 x 40 GMA pallet. Nearly all dry van and reefer trucks are optimized for this size.
- 53′ dry van trailer dimensions (interior): approx. 52’6″ L x 8’6″ W
- Standard pallet size: 48″ L x 40″ W
Maximum Pallet Count for a 53-Foot Trailer
Side-by-side loading (most common):
- You can fit 26 pallets on the floor in a single layer
- 13 rows of 2 pallets
Turned loading (pinwheeling):
- Not typically necessary for 48×40 pallets since side‑by‑side fits cleanly.
Double stacking (if freight allows):
- Up to 52 pallets
- Only possible if freight is stackable, not fragile, and trailer height allows it.
Non-Standard Pallet Sizes (e.g., 60" x 48")
Larger or custom pallet sizes reduce the number of pallets that fit in a standard truckload.
60″ x 48″ Oversized Pallets
- These pallets take up more floor space, limiting configurations.
- Typically, 20–22 pallets fit in a 53’ trailer depending on loading direction.
Examples:
- Loaded lengthwise: ~20 pallets
- Rotated where possible: up to ~22, but only if freight dimensions allow
Other uncommon pallet sizes include 42×42, 48×48, or 40×40. For these, capacity varies depending on the ability to alternate orientations (“turning” pallets) to maximize floor space.
Common Loading Techniques
1. Side-by-Side Loading
The traditional method:
- Two pallets placed next to each other
- Works best with 48×40 pallets
- Achieves the full 26 pallets floor load in a 53′
2. Pinwheel (Turning) Method
- Pallets are alternated at 90° angles
- Helps maximize space with:
- 48×48
- 42×42
- Mixed-size pallet shipments
- Not typically needed for standard 48×40 pallets
3. Double Stacking
Best for:
- Crated shipments
- Boxed freight
- Lightweight products with crush resistance
Can double capacity from 26 to 52 pallets.
However, shippers must verify:
- Trailer height clearance
- Freight stackability
- Carrier approval
4. Single-Stacking with Decking Bars or Load Locks
- Used when freight cannot be stacked directly
- Adds a “second floor”
- Useful for fragile items
Weight Distribution: A Critical Factor Many Shippers Miss
Even if the pallets physically fit, weight distribution can prevent a carrier from taking the load.
Legal Weight Limits in the U.S.:
- Steer axle: 12,000 lbs
- Drive axles: 34,000 lbs
- Tandem axles: 34,000 lbs
- Gross weight: 80,000 lbs
Common Weight Issues
Too much weight in the nose
Causes drive axle overload.Heavy pallets stacked together
Even distribution is crucial.Mixed freight densities
Heavy pallets should be spread evenly throughout the trailer.Double stacking heavy freight
Can exceed trailer or pallet weight limitations.
Best Practices for Balanced Loads
- Place heaviest pallets toward the front but not all at once
- Avoid clustering heavy items
- Distribute weight evenly left-to-right and front-to-back
- Communicate exact pallet weight to your freight broker or carrier
Summary: How Many Pallets Fit in a Truckload?
| Pallet Size | Loading Method | # Pallets (53′ Trailer) |
|---|---|---|
| 48″ x 40″ | Side-by-side | 26 |
| 48″ x 40″ | Double‑stacked | 52 |
| 60″ x 48″ | Standard | 20–22 |
| Mixed sizes | Pinwheel / turned | Varies (usually 20–24) |
