I am thinking about remodeling my existing deck. My deck is 20ft X 21ft and it is 3ft high. I would like to have an opening to the garden which was closed by the railing. So I would like to build stairs with the width of 8ft in order to go from my deck directly into my garden. I searched the web for any maximum deck stairs width but I could not find any information. I know the minimum is 36". Can you give me some ideas?
