To determine how many pallets fit in a 28-foot pup trailer, we need to consider several factors: Dimensions of the trailer: A 28-foot pup trailer typically has internal dimensions of approximately 28 feet long, 8 feet wide, and 9 feet high. Standard pallet size: The most common pallet size in North America is 48 inches by 40 inches. Pallet placement options: Single-stacked: If the pallets are placed only on the floor of the trailer, the number depends on how you orient them and if they are stacked. Double-stacked: If the pallets are double-stacked, you can fit more pallets by utilizing the vertical space. Calculating capacity: Lengthwise (48" side facing forward): Each pallet is 4 feet long, and the trailer is 28 feet long, so you can fit 28/4=7 pallets lengthwise. Widthwise (40" side across the trailer width): Each pallet is 3.33 feet wide, and the trailer is 8 feet wide, so you can fit 8/3.33 ≈2 pallets across. Total pallets: Single-stacked: You can fit 7×2=14 pallets in a single layer. Double-stacked: You can fit 14×2=28 pallets if double-stacked. Thus, you can fit 14 pallets single-stacked or 28 pallets double-stacked in a 28-foot pup trailer, assuming standard pallet dimensions and no additional constraints.
Standard pallets are 4 feet so single file would be 12. If you put them side by side which is common 24.
If they are 4' x 4' then you can fit 2 rows of 12, or 24 pallets. If you can stack the freight 2 high, you can get 48 pallets in there.

Assuming you mean a 48 ft. trailer with at least 96 inches of deck width, and you're using standard 40"x48" pallets, you could fit two across and 14 long for a total of 28 single stacked pallets.
