What changes
The extra height does not add floor positions. Our engine fits 25 EPAL 1 pallets in a single layer in both the standard and the high cube 40 ft container, 23 with handling clearance. What it changes is stacking: tall loads and stacks of empties gain height.
Empty pallets
At 144 mm per EPAL 1, a 2,280 mm door allows 15 pallets per stack; a 2,585 mm door allows 17. Across 23 floor positions that is 345 against 391 empty pallets.
The 45 ft high cube
Leman lists 13,544 mm of inside length for a 45 ft high cube, which our engine turns into 27 EPAL 1 positions, with or without clearance.

Container dimensions vary by builder and age. Our figures come from one published guideline; measure the actual unit if a load is tight.
