Layout
The best layout our engine found puts all 26 in a square grid. That covers 89.8% of the floor.
The same 26 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 reefer container has 37.6 m² of floor (405 sq ft) inside. In the same box an EPAL 1 takes 38 positions against 26 for the CP3, so the CP3 pallets cover 33.8 m² against 36.5 m² for EPAL 1.
The door opening is 2,438 mm wide, so the CP3, carried narrow side first, clears it by 1,298 mm.

Height and weight
Empty CP3 pallets are 138 mm high. The lower of the inside height (2,565 mm) and the door height (2,591 mm) is 2,565 mm, so 18 fit in one stack and 468 across the 26 clearance positions, weighing about not published.
For loaded pallets stacked two high, each unit including its pallet can be at most 1,282 mm tall, which leaves 1,144 mm for goods on each CP3.

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.
