When building stairs or steps for a deck:

• Make sure all of the step risers are the same height, and all the step treads the same width to avoid a tripping hazard.
• The rise of each step is determined by the height of the landing from the ground, with each step height from 7″ to 8″ high.
• The width of each step should be from 11″ to 12″ wide.
• The stringers for the steps are notched at right angles with the proper rise and run.
• After cutting one stringer, use it as a pattern for all the others.
• Notch the top of the stringer so it rests on a ledger board attached to the deck framing.
• Attach deck stair treads with the cup facing down to prevent the steps from holding water or acting as a tripping hazard.
