This construction video tutorial is based on the topic of how to design a straight staircase in a wall.

The design is created on the basis of the following data :-

Height of the wall is taken as = 10 ft
The height of the riser = 7 inches
The length of the tread = 11 inches

In order to find out the numbers of risers, the following formula is used :-
Total height of the wall / Height of the riser = 10/ 0.5833 = 17.14 = 17 Nos. (here inch is converted to feet)

In order to find out the numbers of treads, the following formula is applied :-
Number of risers – 1 = 17 – 1 = 16 Nos
