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 is the code for outdoor steps?

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 span can a 2×4 support?
