In a crib box, what is the maximum stack height relative to its width?

Explanation:
Cribbing stability relies on keeping a safe height-to-base ratio. In practice, the stack height should not exceed three times the width of a single crib box. This 3:1 limit helps prevent buckling, slipping, or tipping under load, especially when the stack is used as a temporary lift or support under dynamic conditions. Keeping the height within this ratio maintains a solid, load-distributing footing. For example, with a crib box width of 6 inches, the maximum safe height would be 18 inches.
