What is the spacing for stair stringers?
Cut stringers can be spaced no more than 18 inches on center, so a 3-foot-wide staircase needs three stringers, and a set of slightly wider stairs (say 3 feet 6 inches) needs four stringers. The maximum 18-inch spacing presumes treads of 5/4-inch wood decking or 2-by stock.
How many stringers do I need for a 36 inch stairs?

What is the correct rise and run for stairs?
The general rule (in the US) is 7-11 (a 7 inch rise and 11 inch run) (17.78cm-27.94cm). More exactly, no more than 7 3/4 inches (19.7cm) for the riser (vertical) and a minimum of 10 inches (25.4cm) for the tread (horizontal or step). You can find some more information here as well on other stair-related dimensions.

How do you calculate rise and run of stairs?
Determining the Run The Rise plus the Run should equal approximately 17.5 inches. (Some designers prefer the formula Two Rise plus the Run should equal between 24 and 25 inches, but whichever formula you use, your staircase should probably have steps 7 inches or so high and treads 10 inches or so deep.)
Should I use 2×10 or 2×12 for stair stringers?
I use 2×12 if there is not an issue with head room below the stairs. Makes a strong set of stairs but it seems the majority of framers around here use 2×10.
What is the minimum run for stairs?
10 inches
Can 2×10 be used for stair stringers?
If you are building code compliant stairs the tread dimension (depth or front to back) needs to be 10″ or more. The rise needs to be 7 1/4″ to not more than 8″. I have never tried to make a 2×10 work but I’m pretty sure that a 2×8 would not work unless you are building something more like a ladder for loft access.
How do you calculate rise over run?
Rise over run formula, calculating by hand All you need to do is calculate the difference between the two points in the vertical direction (rise) and then divide it by the difference in the horizontal direction (run).
