Standard Carrier Shipping Boxes vs. ISO Standard Pallet Sizes
Comparing 2 standards across 15 specifications. 15 key differences identified.
Standard parcel carriers (USPS, FedEx, UPS) define standardized rigid carton tiers, flat rate boxes, and dimensional weight divisor formulas (e.g. Length × Width × Height ÷ 139) that determine billable freight charges across domestic and international logistics networks.
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.
