A double-sided step ladder is provided comprising a first frame having a plurality of spaced apart steps and a second frame having a plurality of spaced apart steps. The plurality of steps on the first frame includes a bottom step located at a first height relative to the base of the ladder with each successive step being spaced apart along the frame at various heights relative to the bottom step of the first frame. The plurality of steps on the second frame also includes a bottom step, the bottom step of the second frame being located at a second height relative to the base of the ladder with each successive step being spaced apart along the frame at various heights relative to the bottom step of the second ladder. The plurality of steps on the first frame and the second frame are located such that the heights of the plurality of steps on the first frame are staggered relative to the heights of the plurality of steps on the second frame.
