How to calculate stair stringer height?
How do I calculate a stair stringer? 1) Start by finding the overall height that the staircase will be. Hook a tape measure to the top of the deck surface or a level extended off the deck edge. Then find and take note of the distance to the ground below. 2) Decide the height or "rise" you'll want for each step.
How deep should a stair tread be?

Where are the weak points in stringers?
The weak points in your stringers are at the V point of the landing notch. The downward pressure (load) is concentrated on the middle area of the level cut on the landing. Picture the tread/riser broken off with the wood grain, and the notched area splitting at the v notch. You'll be left with a 4" piece (rip) of material carrying the center treads. Your set is small, I wouldn't worry. If you had a longer set, I always level cut the waste piece overhanging the landing (air wood) the thickness of a 2x6, or two. Add them to give total support.
