Using the total calculated rise of 119 3/8 inches, divide this by the total number of risers (16). This calculation yields an individual riser height of 7 7/16 inches. This ensures all risers are equal in height, which is essential for safety and craftsmanship. Simultaneously, determine the desired tread depth (run). A standard tread depth of 10 inches is chosen for this staircase. These two dimensions (7 7/16" rise and 10" tread) will be used to mark the stringers.

And that is from the top of the floor down to here. So, we're going to divide that by 16. I think it was 119. Yeah. 119 and 38. Always double check yourself twice. So 119 and 3/8 divided by 16 is a 7 and 7/16 riser riser. And we're going to go with a 10-in tread. I have to figure out where my two landings are. So if I look at this guy
