Staircase Calculator
Calculate rise, run, number of steps, and stringer dimensions for building code-compliant stairs.
How to Use the Staircase Calculator
- 1
Enter total rise
Measure floor-to-floor height in inches or cm.
- 2
Enter desired riser height
Input preferred riser height (7"–7.75" standard).
- 3
View stair layout
See number of steps, tread depth, stringer length, and code compliance.
💡 Tips & Tricks
- •Measure total rise at multiple points — floors are not always perfectly level.
- •All risers must be the same height (within 3/8" per code) to prevent tripping.
- •Use a framing square with stair gauges for accurate stringer layout.
