I am building a set of stairs that is going to a platform that is only about 4 ft high. I am about to trace them out on the wood and assumed that I should use 2x10 wood but I'm second guessing myself and thinking maybe I should use 2x12 wood for the stringers.ou should use a 2x12 if you are cutting them yourself. If you have never cut your own stringers, I would suggest getting precut stair stringers from your local lumber yard or home center.
