Layout
The best layout our engine found puts all 20 in a square grid. That covers 91.9% of the floor.
The same 20 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 40 ft dry container has 28.3 m² of floor (305 sq ft) inside. In the same box an EPAL 1 takes 25 positions against 20 for the CP3, so the CP3 pallets cover 26.0 m² against 24.0 m² for EPAL 1.
The door opening is 2,340 mm wide, so the CP3, carried narrow side first, clears it by 1,200 mm.

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

Height and weight
Empty CP3 pallets are 138 mm high. The lower of the inside height (2,383 mm) and the door height (2,280 mm) is 2,280 mm, so 16 fit in one stack and 320 across the 20 clearance positions, weighing about not published, which is over 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 1,002 mm for goods on each CP3.
If all 20 clearance positions are filled in one layer, the guideline payload allows on average 1,332 kg of goods per pallet.

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.
