To calculate staircase size, begin by measuring the total rise. This is the measurement from the finished floor below to the finished floor level above. You can then calculate the number of risers required. To stay within Building Regulations, a domestic staircase needs a rise of between 190mm and 220mm.
How do you calculate stairs for stairs?
Divide the overall change in level (overall rise) by 150mm.
- 450mm / 150mm = 3. This tells us that with a riser of 150mm we will need 3 risers/steps.
- 450mm / 2 = 225mm.
- Twice the Rise plus the Going (2R + G) should be between 550mm and 700mm.
- 2 x 150mm + 275mm = 575mm.
