Enter the total staircase run (ft) and the total number of stairs into the Stair Length Calculator. The calculator will evaluate the Stair Length.

## Stair Length Formula

The following two example problems outline the steps and information needed to calculate the Stair Length.

**SL = SR / #S**

- Where SL is the Stair Length (ft)
- SR is the total staircase run (ft)
- #S is the total number of stairs

## How to Calculate Stair Length?

The following example problems outline how to calculate Stair Length.

Example Problem #1:

- First, determine the total staircase run (ft).
- The total staircase run (ft) is given as: 50.

- Next, determine the total number of stairs.
- The total number of stairs is provided as: 20.

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

SL = SR / #S

The values provided above are inserted into the equation below and computed.

SL = 50 / 20 = 2.5 (ft)

Example Problem #2:** **

For this problem, the variables required are provided below:

total staircase run (ft) = 60

total number of stairs = 30

Test your knowledge using the equation and check your answer with the calculator..

SL = SR / #S** = ?**
