Intermodal Shipping Containers vs. ISO Standard Pallet Sizes
Comparing 2 standards across 15 specifications. 15 key differences identified.
Standard ISO ocean freight containers are engineered under ISO 668 and ISO 1496 into 20-foot and 40-foot standardized modular lengths with 8-foot widths and 8'6" standard or 9'6" High Cube heights. Equipped with ISO corner castings, they enable seamless transfer across cargo ships, trains, and semi-trucks.
Standard shipping pallets are globally regulated under ISO 6780 into six standardized dimension footprints. The European EUR-1 pallet (800 × 1200 mm) and North American GMA pallet (48 × 40 inches / 1016 × 1219 mm) dominate over 80% of global automated warehousing and intermodal freight transport.
