How Do I Calculate Stairs?

1. Calculate the number of steps that will be needed: Considering an ideal riser of 18 cm, the height of the space is divided by the height of each step. The result should always be rounded up: 260/18 = 14.44 = 15 steps
2. Calculate the height of each riser: The height of the space is divided by the number of steps that we have just obtained:260/15 = 17.33 cm height for each riser
3. Calculate the width of the tread: Apply the Blondel formula: (2 x 17.33 cm) + (1 x tread) = 64, Each tread will measure 29.34 cm.
