Building Stairs....HELP

Building stairs off my front porch.

30" to the ground.

I've figured out i'll need 4 steps at 7.5" rise each. 10" run. Top step even with the porch.

I just use a regular square right to lay out my stringers?

Put a mark at 7.5 on the thin side and 10 on the thick side and line it up and mark my lines right?

Sorta like this...Top left corner...

 

I believe so..but after doing a set of porch stairs with a friend..we both agreed perfect stairs should be left for a professional stair maker XD

 

Yes , you use a framing square and yes , put one side on 7 1/2" ( rise ) and one side on 10" ( run )

After you cut those out you need to reduce the bottom rise by the thickness of the boards you are going to put on the stringers for steps

For example , if you are going to use standard 2x material , which is 1 1/2" thick , you need to reduce your bottom rise by 1 1/2" , or to 6" in your case
