What is the recommended ladder angle for a stable setup?

• A. About 75 degrees
• B. About 60 degrees
• C. About 45 degrees
• D. About 30 degrees

Answer: (A)

Setting a ladder at about 75 degrees gives the best balance between stability and usability. This angle follows the common four-to-one rule: for every four feet of height you plan to reach, place the base about one foot from the wall. That setup keeps the ladder’s center of gravity over its feet, reducing the chance of tipping and preventing the top from sliding down the wall.

If the ladder is steeper, it becomes more prone to tipping backward because there isn’t enough counterweight at the base. If it’s shallower, the base tends to slip outward and the top contact with the wall becomes unstable, increasing the risk of a fall. So, around 75 degrees is the safest, most reliable choice.
