Layout
The best layout our engine found puts 36 with the 800 mm side along the length and 3 turned with the 1200 mm side along the length. That covers 94.3% of the floor.
The same 39 pallets still fit after leaving 100 mm of length and 50 mm of width free for handling, so this layout has room to spare.
Floor and door
The 53 ft domestic high cube container has 39.7 m² of floor (427 sq ft) inside. The 39 pallets cover 37.4 m² of it.
The door opening is 2,489 mm wide, so the EPAL 1, carried narrow side first, clears it by 1,689 mm.

Height and weight
Empty EPAL 1 pallets are 144 mm high. The lower of the inside height (2,769 mm) and the door height (2,769 mm) is 2,769 mm, so 19 fit in one stack and 741 across the 39 clearance positions, weighing about 18,525 kg.
For loaded pallets stacked two high, each unit including its pallet can be at most 1,384 mm tall, which leaves 1,240 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.
