What is the proper climbing angle of a ladder?

The proper climbing angle of a ladder is crucial for safety and stability when performing tasks at height. An angle of 75 degrees strikes a balance between being steep enough to allow easy access to the top of the ladder and shallow enough to provide a secure footing.

At this angle, the ladder distributes weight effectively, reducing the risk of tipping over and ensuring that the climber has a stable platform to ascend or descend. Maintaining this angle helps to align the ladder against the structure it is leaning against without requiring excessive effort to climb.

Other angles can lead to safety concerns. A 90-degree angle would have the ladder vertical, which can cause instability and make it difficult to climb. A 60-degree angle might be too shallow, increasing the chance of slipping at the base. A 45-degree angle is often too steep, which can put undue stress on the ladder and the person using it. Therefore, the 75-degree angle is recommended as the optimal position for ladder use.
