The base of a ladder should be placed at least what fraction of the working length away from the top support?

Explanation:
This is about maintaining a safe lean angle for a ladder. The minimum distance the base should be from the wall is one quarter of the ladder’s length. This 4:1 rule puts the ladder at a stable angle (roughly 75 degrees) that helps prevent tipping. So if the ladder is 16 feet long, the base should be at least 4 feet from the wall. You can move the base farther out if needed for conditions, but the minimum safe distance is 1/4 of the working length.
