Enter the wall height (ft) and the length away from the wall (ft) into the Calculator. The calculator will evaluate the Wall Angle.

Wall Angle Formula

WA = ATAN (H/L) * 57.2958

Variables:

• WA is the Wall Angle (degrees)
• H is the wall height (ft)
• L is the length away from the wall (ft)

To calculate Wall Angle, take the inverse tangent of the wall height divided by the length away from the wall, then multiply by 57.2958 to express the result in degrees.

How to Calculate Wall Angle?

The following steps outline how to calculate the Wall Angle.

1. First, determine the wall height (ft).
2. Next, determine the length away from wall (ft).
3. Next, gather the formula from above = WA = ATAN (H/L) * 57.2958.
4. Finally, calculate the Wall Angle.
5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem :

Use the following variables as an example problem to test your knowledge.

wall height (ft) = 5

length away from wall (ft) = 4

FAQ

What is the significance of calculating the Wall Angle?

Calculating the Wall Angle is crucial for ensuring the stability and safety of structures, like ladders against a wall, and for architectural and construction purposes to determine the correct angle for support structures.

Can the Wall Angle formula be used for any type of wall and ladder setup?

Yes, the formula is versatile and can be applied to various wall heights and distances, providing a reliable measurement for ladder placement and other structural designs that require precise angle calculations.

How does changing the wall height or the length away from the wall affect the Wall Angle?

Increasing the wall height or decreasing the length away from the wall will increase the Wall Angle, making the slope steeper. Conversely, decreasing the wall height or increasing the length away will decrease the angle, making the slope gentler.

Is there a maximum or minimum Wall Angle for safety reasons?

While the Wall Angle can vary, safety guidelines suggest keeping the angle within a certain range to prevent tipping or falling. For ladders, a commonly recommended angle is around 75 degrees from the ground, but this can depend on the specific application and safety regulations.
