A space saving ladder, wherein the ladder can be folded up into a compact unit for storage. In the open load bearing orientation, the space saving ladder is load bearing and conforms to requirements for free standing ladders. In the closed orientation, the space saving ladder can have steps or rungs, which can hinge upward as the ladder legs are moved closer to one another. In the closed orientation, the legs of the space saving ladder are adjacent to one another and the steps or rungs are enclosed in the ladder legs.
