## Ceiling Slope Formula

The following formula is used to calculate the Ceiling Slope.

CS = tan^-1(CH/CL)

- Where CS is the Ceiling Slope (degrees of slope)
- CH is the difference in height
- CL is the length of the ceiling

To calculate a ceiling slope, take the inverse tangent of the difference in height divided by the length of the ceiling.

## How to Calculate Ceiling Slope?

The following example problems outline how to calculate Ceiling Slope.

Example Problem #1:

- First, determine the difference in height.
- The difference in height is given as: 400.

- Next, determine the length of the ceiling.
- The length of the ceiling is provided as: 600.

- Finally, calculate the Ceiling Slope using the equation above:

CS = tan (CH/CL)

The values given above are inserted into the equation below and the solution is calculated:

CS = tan-1 (400/600) = 33.69 (degrees of slope)

Example Problem #2:** **

For this problem, the variables needed are provided below:

difference in height = 700

length of the ceiling = 1500

This example problem is a test of your knowledge on the subject. Use the calculator above to check your answer.

CS = tan^-1 (CH/CL)** = ?**
