What determines the size of a single ladder?

• A. Width of the rung
• B. Material type
• C. Weight rating
• D. Overall length of the side rail

Answer: (D)

Size of a single ladder is determined by the overall length of the side rails. That length defines how high you can reach when you climb it, which is what we mean by the ladder’s size. The width of the rung affects comfort and footing but not the ladder’s height. Material type influences weight and durability, not the size. The weight rating tells you how much load it can safely carry, not how tall the ladder is. So the length of the side rails sets the ladder’s size.
