What is the stack height limit for plastic pallets?

• A. 3 ft high
• B. 5 ft high
• C. 7 ft high
• D. 6 ft high

Answer: (B)

The height limit for stacking plastic pallets is five feet. This limit keeps loads stable during storage and movement, so pallets don’t tip or collapse when moved by forklifts or jacks. It also ensures there’s enough clearance for safe handling, visibility, and avoiding contact with racks or overhead structures. Plastic pallets are sturdy, but stacking higher can compromise balance, especially as loads settle or vibrate during transport. A five-foot limit efficiently uses vertical space while prioritizing safety. Lower heights would underutilize space, while higher heights would require special handling and increase risk.
