Question

ladder rungs should be spaced between
______ and ______ inches apart.
2...4
4...6
6...10

Ladder safety standards (e.g., OSHA) specify rung spacing. 6 - 10 inches ensures stability and user safety. Smaller gaps (e.g., 2 - 6) might be too cramped, larger (10 - 14) risk instability.

6...10
