Layout
The best layout our engine found puts 15 with the 800 mm side along the length and 10 turned with the 1200 mm side along the length. That covers 84.8% of the floor.
Leaving 100 mm of length and 50 mm of width free for handling costs 2 positions: the clearance layout puts 14 with the 800 mm side along the length and 9 turned with the 1200 mm side along the length.
Floor and door
The 40 ft dry container has 28.3 m² of floor (305 sq ft) inside. The 25 pallets cover 24.0 m² of it.
The door opening is 2,340 mm wide, so the EPAL 1, carried narrow side first, clears it by 1,540 mm.

| Inside height | 2,383 mm |
| Door opening, width × height | 2,340 × 2,280 mm |

Height and weight
Empty EPAL 1 pallets are 144 mm high. The lower of the inside height (2,383 mm) and the door height (2,280 mm) is 2,280 mm, so 15 fit in one stack and 345 across the 23 clearance positions, weighing about 8,625 kg, which is within the 26,650 kg guideline payload.
For loaded pallets stacked two high, each unit including its pallet can be at most 1,140 mm tall, which leaves 996 mm for goods on each EPAL 1.
If all 23 clearance positions are filled in one layer, the guideline payload allows on average 1,133 kg of goods per pallet, after the pallet's own 25 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.
