This is known as a space-saving staircase because it takes up very little square footage in a home, which can free up a large area of the room if you were to replace a standard staircase with this type.

The smallest size of spiral staircase available from most manufacturers will have a diameter measurement of 3 feet and 6 inches. It is this design that means a spiral staircase is great for saving space because it will go directly up to the next floor, rather than diagonally across a room like most staircases.īecause the pole is in the center of the staircase, there is only a handrail on the outside of the staircase, so it might not be the best type of staircase to use for anyone who is a little unsteady on their feet.Īdded to this, spiral staircases tend to be steeper than regular staircases, which might be a safety concern for some people, such as those with children or elderly users. It is this central pole that provides the structural integrity of the stairs, and therefore no other reinforcements or supports are needed. Typically, spiral staircase sizes vary with the smallest standard spiral staircase having a diameter measurement of 3 feet 6 inches and a walking path width measurement of 17 inches to the largest standard spiral staircase with a diameter measurement of 6 feet and a walking path width measurement of 32 inches.Ĭheck out the drawing below with great details.Ī spiral staircase is based around a central pole, with a simple design that makes installation quicker and easier than a regular staircase.
