When the casting is completed, the flooring of stair is started and it becomes very important to work out the height of riser. Here we will provide some useful guidelines for calculating the height of riser.

In video tutorial given below, the height of floor finish level to floor finish level is taken as 2790 mm or 2.79 m.

Assume the number of risers as 18 nos.

The following formula is used to calculate the height for stair flooring.

(FFL to FFL Height/No. of riser) – the thickness of marble

i.e. 2790/18 – 15 (marble thickness is taken as 15 mm) = 140 mm
