What is the recommended distance between the foot of a straight ladder and the base of the wall or support?

The recommended distance between the foot of a straight ladder and the base of the wall or support is one-fourth of the working length of the ladder. This guideline is based on ensuring safety and stability when using a ladder.

Understanding the balance of forces acting on a ladder helps clarify this recommendation. When a ladder is positioned too steeply or too flat, it can become unstable, increasing the risk of sliding or tipping over. The one-fourth rule provides a sufficient angle that maintains the ladder's balance while also allowing the user to safely climb and descend.

This proper positioning also aligns with safety standards established by organizations dedicated to promoting safe working practices. By adhering to the one-fourth distance guideline, users can maximize the ladder's efficiency and minimize hazards associated with improper ladder placement.
