Step Size

The steps are 42.125" wide and 11.25" deep with a 1.125" nosing

Rise

edit

The top of the 2nd story flooring is 121.375" from the top of the sill. We also need to add 1.5" from the basement slab to the sill = 122.875" total rise

The actual stairway rise will depend on the height of the landing:

With 2x6s and 3/4" planks (6.25" total) it will need to be 116.625"

With 2x8s and 3/4" planks (8" total) it will need to be 114.875"


15 steps of 7-3/4" (the maximum allowed by code) is 116.25"

15 steps of 7-5/8" provides 114.375"


The landing or the top step can be adjusted to make up the difference

FreeCAD workbench to generate stairs

(Note: The generated steps need to be rotated 180 degrees for use in SEH2. If you create a simple copy, you can set the placement angle to 180 deg and then adjust the x, y, and z position to position the stairs. x=349.35" and y=186.125" should align them in the stairwell. Adjust z as needed to move them up or down to meet the landing.)
