## How to Calculate Stair Stringers
### Formula
**Number of Risers = round(Total Rise / Desired Riser Height)**
**Actual Riser = Total Rise / Number of Risers**
**Number of Treads = Number of Risers - 1**
**Total Run = Number of Treads × Tread Depth**
**Stringer Length = sqrt(Total Rise² + Total Run²)**
Building code typically requires: Max riser height 7-3/4 inches, min tread depth 10 inches, and the riser + tread combination should fall between 17 and 18 inches.

हल किया गया उदाहरण
A staircase with 108 inches (9 feet) of total rise, 7.5" desired risers, 10" treads, 36" wide.
- Number of risers = round(108 / 7.5) = 14 risers
- Actual riser height = 108 / 14 = 7.714 inches
- Number of treads = 14 - 1 = 13 treads
- Total run = 13 × 10 = 130 inches (10.83 ft)
- Stringer length = sqrt(108² + 130²) = sqrt(28,564) = 169 inches (14.1 ft)
- Stringers needed = 3 (for 36" width)
