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:

1. First, determine the total staircase run (ft).
• The total staircase run (ft) is given as: 50.
2. Next, determine the total number of stairs.
• The total number of stairs is provided as: 20.
3. 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
