Stairs are usually eight (7) inches high. A fair estimate for the height of a building floor is ten feet. As a result, traveling up one story takes around 21 steps. A decent estimate for climbing to the top of an eight-eighth-story structure is that you will have to climb 21 x 8, or 168 steps. The actual number may be higher or lower depending on how steep the stairs are and how quickly you walk up them. The exact number of steps in a staircase is determined by how many feet there are from the bottom to the top of the staircase. If the staircase is six feet tall, then it has six floors of steps. If it's twenty-one feet tall, then it has twenty-one floors of steps. In general, the more feet you are from the bottom to the top of the staircase, the more steps there will be. This is because each step is seven inches high, so twenty-one steps is about as much as you can get. However, if the staircase is built with additional space above itself (such as a landing or balcony), then you could have more than twenty-one steps. There are two ways to determine how many steps are on a floor. The first is to count them. This is not difficult if they are not covered by anything else (such as carpet). You just need to be aware of where the edge of each step is. The second way is to use a tape measure.
