## How to Calculate Stair Risers
### Formula
**Number of Risers = round(Total Rise / Target Riser Height)**
**Actual Riser Height = Total Rise / Number of Risers**
**Number of Treads = Risers - 1**
The International Residential Code limits risers to a maximum of 7-3/4 inches and requires a minimum tread depth of 10 inches. A common comfort rule is that riser + tread should equal 17 to 18 inches.

हल किया गया उदाहरण
A floor-to-floor height of 108 inches (9 feet) with a 7.5-inch target riser and 10-inch treads.
- Number of risers = round(108 / 7.5) = round(14.4) = 14 risers
- Actual riser height = 108 / 14 = 7.714 inches
- Number of treads = 14 - 1 = 13 treads
- Total run = 13 x 10 = 130 inches (10 ft 10 in)
- Comfort check: 7.714 + 10 = 17.71 in (within the 17-18 range)
