The width of the steps is flexible. A wide deck staircase (5 feet and beyond) feels graceful and looks it too. A narrow one, for example 3 feet wide, might feel cramped. Very wide steps are great...if you have the room for them and they work with your design. These usually work best with a single set of deck stairs.
Local codes typically specify stair step width limits. Usually the minimum for residences is from two feet eight inches to three feet six inches. There are no maximum widths, but stairs wider than 44 inches may require hand rails. Local codes may require landings for staircases that rise more than a total of 12 feet.
