Stair Stringer Calculator
A stair stringer calculator helps determine precise measurements for building safe and code-compliant stairs. It calculates the correct dimensions for rise, run, and stringer length, ensuring proper weight distribution and safety. This tool is essential for DIY enthusiasts and professionals to avoid measurement errors and create stairs that meet building regulations.
Calculation Results:
Number of Rises:
Actual Rise Height: "
Number of Runs:
Run Depth: "
Stringer Length: "
Formula Used:
Number of Rises = Total Height / Desired Rise Height
Number of Runs = Number of Rises - 1
Stringer Length = √(Total Height² + Total Run²)
| Component | Ideal Measurement |
|---|---|
| Rise Height | 7-7.75 inches |
| Run Depth | 10-11 inches |
| Stringer Width | 11.5 inches minimum |
