Layout
The best layout our engine found puts 14 with the 1100 mm side along the length and 12 turned with the 1300 mm side along the length. That covers 93.6% 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 high cube container has 39.7 m² of floor (427 sq ft) inside. In the same box an EPAL 1 takes 39 positions against 26 for the CP4, so the CP4 pallets cover 37.2 m² against 37.4 m² for EPAL 1.
The door opening is 2,489 mm wide, so the CP4, carried narrow side first, clears it by 1,389 mm.

Height and weight
Empty CP4 pallets are 138 mm high. The lower of the inside height (2,769 mm) and the door height (2,769 mm) is 2,769 mm, so 20 fit in one stack and 520 across the 26 clearance positions, weighing about not published.
For loaded pallets stacked two high, each unit including its pallet can be at most 1,384 mm tall, which leaves 1,246 mm for goods on each CP4.

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.
