Layout
The best layout our engine found puts 15 with the 800 mm side along the length and 40 turned with the 600 mm side along the length. That covers 93.5% of the floor.
Leaving 100 mm of length and 50 mm of width free for handling costs 3 positions: the clearance layout puts 14 with the 800 mm side along the length and 38 turned with the 600 mm side along the length.
Floor and door
The 40 ft open top container has 28.2 m² of floor (304 sq ft) inside. In the same box an EPAL 1 takes 25 positions against 55 for the EPAL 7, so the EPAL 7 pallets cover 26.4 m² against 24.0 m² for EPAL 1.
The door opening is 2,338 mm wide, so the EPAL 7, carried narrow side first, clears it by 1,738 mm.

Height and weight
Empty EPAL 7 pallets are 163 mm high. The lower of the inside height (2,330 mm) and the door height (2,234 mm) is 2,234 mm, so 13 fit in one stack and 676 across the 52 clearance positions, weighing about 6,422 kg, which is within the 31,570 kg guideline payload.
For loaded pallets stacked two high, each unit including its pallet can be at most 1,117 mm tall, which leaves 954 mm for goods on each EPAL 7.
If all 52 clearance positions are filled in one layer, the guideline payload allows on average 597 kg of goods per pallet, after the pallet's own 9.5 kg.

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.
