Handy magazine shows you how to build basic stair stringers.
Stair stringer square.
Align the rise and run measurements on the square with the edge of the stringer.
This will establish the starting point for the stringer.
Screw them onto a framing square once you know your rise and run such as for stair stringers.
This will create a stair stringer calculator.
Pros recommend a width of 16 between stringers but depending on the stairs and the thickness of the tread that figure could be slightly higher.
Get a carpenters framing square and if you have little buttons that clamp or screw onto the square even better.
Trace out the unit rise and unit run as shown by the measurements on the square.
The above image shows drawing the top step run at 10 and the rise at 6 3 8.
Use the narrow part of the square for clamping the riser gauge and the wider part for the 10 1 4 in.
Lay out the stairs by drawing on the outside of the square sliding the square along until it meets the last mark to learn how to build steps.
Notice that the stair stringer top step has a 9 run and the next step has a 10 run.
The lumber is pressure treated protecting it from termites and rot.

My gauges came with a ball bearing in the slot where.
Ideal for a variety of applications including decks docks and other outdoor projects where lumber is exposed to the elements.

A 42 wide outdoor set of stairs should have 3 stringers 2 x 12 typically.
The back tread for the top step had to be ripped down to fit the opening.
One of these tools will allow you to lay out consistent precise angles down the length of the board.
