What is the formula to build steps?
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).
What material is used for stairs?
Concrete is the commonly used material to construct a stairway. A plus point of using it is that it conveniently takes the shape you desire for your stairs. Curved and spiral staircases are the usual examples of staircase designs that can be easily made from concrete.
Can I use 2×10 for stair stringers?
Pressure-treated or cedar 2×10 or 2×12 can be used depending on the depth of the cut-outs you’ll be using. By code you will need a minimum of 3-1/2″ of material left on the stringer after the cut-outs and that area should also be free of large knots which would weaken the stringer.
What is the code for outdoor steps?

What size wood do you use for steps?
Stair treads may be made of a single 2×12, but are often made of two decking boards or 2x6s. A stringer is a wide board, usually a 2×12, that runs at an angle from the landing pad to the deck framing and supports the treads.
Can I use 2×4 for deck steps?
Either way, 2x4s as deck joists are safe as long as your design doesn’t span too far or include guard rails or stairs.
