Number of steps
Calculated by dividing the total rise by the step height. A single flight has 3 to 16 steps (optimally 11–15).
01 /Algorithm for the number of steps
The number of steps is calculated by dividing the total rise by the optimal height of a single step. For biomechanical reasons, a single flight should have 3 to 16 steps (optimally 11–15).
- Measure the height (H). Measured strictly from the finished floor of the first storey to the finished floor of the second.
- Choose the step height (h). For a home the ideal riser height is 15–18 cm.
- Calculate the count (N). Divide the total height by the chosen step height: N = H / h.
- Rounding. The result is always rounded to a whole number. An odd number of steps is preferable — it is more convenient to start and finish the climb on the same foot.
02 /Important rules
Equal height. All steps along the entire staircase must be exactly the same height (a deviation of no more than 5 mm is allowed). A difference in step height is the main cause of stumbles and injuries.
Use of landings. If the calculated number of steps exceeds 16–18, the flight must be split by an intermediate landing.
