What is the correct angle for a ladder leaning against a wall?

The correct angle for a ladder leaning against a wall is typically around 75 degrees. This angle provides a good balance between stability and reach. When positioned at this angle, the ladder maintains a safe and secure base, reducing the risk of slipping or tipping over while in use.

At a 75-degree angle, the ladder allows for a comfortable ascent and descent, while also ensuring that the weight distribution is optimal. This angle is commonly recommended in ladder safety guidelines, ensuring that users can safely work at height without excessive strain or risk of falling.

Other angles are either too steep or too shallow, which can compromise the ladder's stability and usability. A steeper angle, such as 80 degrees, may feel less stable and increase the risk of falling backward. Conversely, a shallower angle, like 65 degrees, may make the ladder more prone to sliding out from the base. Therefore, the choice of a 75-degree angle is a balance of safety and practicality for ladder usage.
