Layout
The best layout our engine found puts 38 with the 800 mm side along the length. That covers 97.0% of the floor.
Leaving 100 mm of length and 50 mm of width free for handling costs 1 position: the clearance layout puts 34 with the 800 mm side along the length and 3 turned with the 1200 mm side along the length.
Floor and door
The 53 ft domestic reefer container has 37.6 m² of floor (405 sq ft) inside. The 38 pallets cover 36.5 m² of it.
The door opening is 2,438 mm wide, so the EPAL 1, carried narrow side first, clears it by 1,638 mm.

Height and weight
Empty EPAL 1 pallets are 144 mm high. The lower of the inside height (2,565 mm) and the door height (2,591 mm) is 2,565 mm, so 17 fit in one stack and 629 across the 37 clearance positions, weighing about 15,725 kg.
For loaded pallets stacked two high, each unit including its pallet can be at most 1,282 mm tall, which leaves 1,138 mm for goods on each EPAL 1.

How this is computed
The engine tries every split of the deck into rows of pallets placed one way and rows placed the other way, along the length and across the width, and keeps the arrangement with the most pallets. It does not overhang, mix in other pallet sizes or allow for bulging goods. The methodology page explains each step, and the load planner runs the same code on your own dimensions.
