I need to build a small deck stair. My total rise is 24.5 inches. I am planning a rise of 6.125 inches per step. But what should the run be? I consulted three deck building books and got answers ranging from
11 inches to 16 inches! Quite a spread. People don't seem to adhere to the same rules (e.g. the 17 rule) as for interior stairs. I was thinking I could use four 4 inch deck boards which would give me a tread of about 14 inches which is in the middle of the range recommended in the books. Is that reasonable?- posted
