Just wanting to get some other opinions for stair rise/run. I am in the planning stages of lengthening my steep basement stairs and finishing two rooms in the basement. Here is the situation, current rise/run of the staircase is 9.65"/8.22"... yes thats almost 1.5" more rise than run for each step. I am removing one floor joist and a closet upstairs to gain the headroom. With the added length my options are 12 steps with 8.04"/9.27" or 13 steps with 7.42"/8.5" I want to get some opinions on what would yield the most comfortable staircase -- an approx 8" rise with a 9.25" run or a 7.5" rise and 8.5" run. Also any thoughts on cutting the stair stringers at an angle to yield extra tread for each step?
