Enter the height of each stair (in) and the length of each stair (in) into the Stair Slope Calculator. The calculator will evaluate and display the Stair Slope.

## Stair Slope Formula

The following formula is used to calculate the Stair Slope.

**SS = HS / LS**

- Where SS is the Stair Slope ( )
- HS is the height of each stair (in)
- LS is the length of each stair (in)

## How to Calculate Stair Slope?

The following example problems outline how to calculate Stair Slope.

Example Problem #1:

- First, determine the height of each stair (in).
- The height of each stair (in) is given as: 12.

- Next, determine the length of each stair (in).
- The length of each stair (in) is provided as: 13.

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

SS = HS / LS

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

SS = HS / LS = .923

Example Problem #2:** **

For this problem, the variables needed are provided below:

height of each stair (in) = 15

length of each stair (in) = 20

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

SS = HS / LS** = ?**
