How to calculate stair stringer rise
This calculator finds stair stringer rise per step by dividing total rise by the number of risers.
How the calculation works
Rise per step = Total rise ÷ Number of risers.
Example
84 inches of total rise across 12 risers: 84÷12 = 7 inches per step.

Pro Tips for Stair Stringer Rise
- This resulting rise-per-step figure must be consistent across every step (per most building codes, within about 3/8 inch tolerance) for stair safety.
- Cross-check the resulting rise-per-step against your local building code's maximum allowed riser height before cutting stringers.
Common Stair Stringer Rise Mistakes to Avoid
- Not verifying the calculated rise-per-step falls within your local code's allowed range before cutting stringers, which could require rework if it doesn't comply.
