Determining Run of Staircases
In a straight staircase, there will always be one fewer stair tread than riser. This is to account for the additional rise needed to meet up with the top floor. Using this rule of thumb to refer back to the previous example of the 104” floor to floor 13 rise staircase, there will be 12 treads.
