Standard pallets are 4 feet so single file would be 12. If you put them side by side which is common 24.

Yes, If load the pallets sideways and double stack them you can fit 60 pallets on a 53' trailer

Trailer 53' - 110" high - 2 rows of 15 stacked 18 high for a total of 540 pallets
48 feet/4 feet =12 x 2 sides of the trailer =24 pallets.
Trailer 53' - 110" high - 2 rows of 15 stacked 18 high for a total of 540 pallets
A 48 foot trailer can hold about 24 standard pallets. Each pallet is 4 feet by 4 feet, and the trailer is about 8 feet wide.

22 is the minimum count.
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.
Using typical 4'x4' pallets, you can fit two rows of 13 pallets in a 53' box van, and can stack them however high your payload permits you to within 110 inches (the typical inside height of such a trailer). Typical retail trade distribution and logistics is supported by the use of 40" x 48" pallets. A typical 53 foot trailer will fit two rows of 15 pallets if the pallets are turned. It makes it more difficult to load and unload in that typical 40" x 48" pallets are designed to be lifted from the smaller of the two widths - 40" side. The pallets can not be lifted from the 48" side using common pallet jack lift equipment - pump jacks and/or battery operated jacks. Ease of loading and unloading can be best supported by the use of counter-balance or sit-down fork trucks granted that the height of the mask permits entry into the trailer.
