Begin by determining the total vertical height from the top of the deck surface to the ground where the stairs will land. In the video, this measurement is around 62-63 inches. For a comfortable and safe staircase, individual risers should not exceed 7 to 8 inches. Divide the total height by a desired riser height (e.g., 7 inches) to calculate the number of steps needed (e.g., 63 inches / 7 inches = 9 steps). Since each step's tread will be approximately 1 foot deep, multiply the number of steps by 1 foot to determine the total horizontal projection (run) of the staircase (e.g., 9 steps * 1 foot/step = 9 feet). This calculation ensures the stairs will extend far enough out from the deck.
