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.
This is the height each stair riser needs to be. A typical tread is right around 10 inches. The amount of treads will be one less than the amount of risers(14 treads), to find the total run or length of a single run staircase, multiply 10 by 14 and that tells you your stairway will be 140 inches long. The width of typical stairs is four feet. A space of 140 x 48 will accommodate the staircase in this example. The equation for determining the amount of risers is standard for any style of stairs, however, figuring how much floor space your staircase will take up depends on which design you choose.
