2xRiser + 1xTread = 25" to 27"

Measure the height that you need to go and the length that you have to work with. Most carpenters like to use 7-1/4" risers with 11-1/2 " treads inside of houses. Outdoor situations often have different slopes to follow. You have to be careful because there is a certain range of rhythm in the way people walk. If you don't set your rise and run (riser/tread) right, people will trip (and maybe get hurt and/or sue you).

Another example would be a 4" riser with 18" tread [(4x2)+18=26].

from what elevation to what elevation = height
horizontal distance (level from point A to point B) is what I mean by length.
You can't do too much in the way of designing stairs if you don't know those two things.

The good thing about wood framed stairs with stringers is that you can use the standard rise and run that you would use in a house and adjust it to the slope by keeping it elevated off of the slope and using landings to adjust to the specific slope. BUT, you still need to know the slope to design it ahead of time.
