Layout
The best layout our engine found puts 14 with the 760 mm side along the length. That covers 96.9% of the floor.
Leaving 100 mm of length and 50 mm of width free for handling costs 3 positions: the clearance layout puts 7 with the 760 mm side along the length and 4 turned with the 1140 mm side along the length.
Floor and door
The 20 ft reefer container has 12.5 m² of floor (135 sq ft) inside. In the same box an EPAL 1 takes 10 positions against 14 for the CP5, so the CP5 pallets cover 12.1 m² against 9.6 m² for EPAL 1.
The door opening is 2,290 mm wide, so the CP5, carried narrow side first, clears it by 1,530 mm.

Height and weight
Empty CP5 pallets are 138 mm high. The lower of the inside height (2,273 mm) and the door height (2,221 mm) is 2,221 mm, so 16 fit in one stack and 176 across the 11 clearance positions, weighing about not published, which is over the 27,700 kg guideline payload.
For loaded pallets stacked two high, each unit including its pallet can be at most 1,110 mm tall, which leaves 972 mm for goods on each CP5.
If all 11 clearance positions are filled in one layer, the guideline payload allows on average 2,518 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.
