I have a interior landing (a room entrance) sitting at 12 inches from the floor. I'm having trouble running the numbers on the stringer calculation since dividing the total rise by 7 is 1. That means 1 step (tread).
Technically I need 2 steps (treads) including the tread which is at the TOP of the stairs which should sit flush with the landing.
How can this calculation account for this top step? Also, for this short height, I'm assuming I need wider treads -- any tips to calculate this would be excellent.
