Standard Stair Rise and Run Calculator

What is a Standard Stair Rise and Run Calculator?

A Standard Stair Rise and Run Calculator is a tool used to calculate the optimal dimensions for a set of stairs, ensuring that they meet building codes and safety standards.

It helps determine the ideal height of each step (rise) and the horizontal distance between each step (run).

Why Use a Standard Stair Rise and Run Calculator?

This calculator is essential for architects, builders, and homeowners who need to design stairs that are safe and comfortable to use.

Stairs with the correct rise and run dimensions are easier to ascend and descend and minimize the risk of accidents.

How to Use a Standard Stair Rise and Run Calculator:

1. Enter the total rise in inches (the vertical height from the lower floor to the upper floor).
2. Enter the desired run in inches (the horizontal distance between each step).
3. Click the "Calculate Stair Dimensions" button.
4. The calculator will display the optimal rise and run dimensions based on building codes.

Example Calculation:

• Total Rise: 96 inches
• Desired Run: 10 inches

Optimal Rise ≈ 7.11 inches Optimal Run = 10 inches

In this example, for a total rise of 96 inches and a desired run of 10 inches, the optimal rise is approximately 10.67 inches, and the optimal run remains at 10 inches.

These dimensions meet building codes and safety standards for a set of stairs with comfortable step dimensions.
