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.
At left our photo illustrates three different stair width measurements. 1  Stair tread width (green arrow) (smaller than stairway width due to side trim boards) 2  Stairway width (blue arrow) over most of this stairway (nominally 36) 3  Stairway width near stair top (pink arrow) due to a wall projection (nominally 35)
