How Many Pallets Fit in a 53-Foot Trailer?

A standard 53-foot dry van trailer is the workhorse of the American logistics industry. Understanding its capacity is critical for shipping efficiency and cost reduction. Generally, a 53-foot trailer can accommodate 26 to 30 standard GMA pallets (48″ x 40″) on the floor level.

The Role of Pallet Orientation

The total number of pallets depends heavily on how they are oriented inside the trailer:

• Straight Loading: Pallets are loaded with the 40-inch side facing the rear door. Since a trailer internal width is roughly 99 inches, two 40-inch pallets fit easily side-by-side (80 inches total). Over the 636-inch length, you can fit 13 rows of 48-inch deep pallets, totaling 26 pallets.
• Turned (Side-Loading): Pallets are rotated so the 48-inch side faces the rear. Two 48-inch pallets take up 96 inches of the 99-inch width. Because the depth is now only 40 inches, you can fit 15 rows, totaling 30 pallets. This is often called "pinwheeling" if some are turned and others are straight to maximize space.

Standard 53ft Trailer Dimensions

Dimension	Standard Measurement
External Length	53 Feet (636 Inches)
Internal Width	~98 to 99 Inches
Internal Height	~110 Inches

Double Stacking Considerations

If your cargo is light enough and the pallets are sturdy, you can double stack. This effectively doubles your capacity to 52 or 60 pallets. However, you must ensure you do not exceed the legal weight limit, which is typically 44,000 to 45,000 lbs for the cargo in a standard tractor-trailer setup.

Example Calculation

If you are shipping standard 48″x40″ pallets using a straight loading pattern:

1. Trailer Length (636″) / Pallet Length (48″) = 13.25 rows.
2. Usable rows = 13.
3. Width Check: 40″ x 2 = 80″ (Fits inside 99″ width).
4. Total = 13 rows x 2 pallets = 26 pallets.
