**You divide the height by 7 inches; if, say, the floor-to-floor distance is 8 feet, 10 inches (or 106 inches), then you’ll need 15 treads (106 divided by 7 equals 15.14). Next, you divide the height by the number of treads (15 into 106), producing the exact tread height (7.06 inches).**

Moreover, How do you calculate number of steps?

Divide the rise by 6 or 7 inches (15 or 18 cm) to find the total number of stairs. For larger stairs, divide by 6 and for smaller stairs, divide by 7. The total you get is how many stairs your future staircase will have so you can plan accordingly.

How do I calculate how many steps I need for a deck?

Furthermore, What is the formula for building stairs?

Determining the Rise You divide the height by 7 inches; if, say, the floor-to-floor distance is 8 feet, 10 inches (or 106 inches), then you’ll need 15 treads (106 divided by 7 equals 15.14). Next, you divide the height by the number of treads (15 into 106), producing the exact tread height (7.06 inches).
