Abstract
A stairway system is disclosed that includes a plurality of spaced apart treads; a handrail; and at least two balusters per tread. Each baluster includes a top length segment, a bottom length segment and a turning length segment, the turning length segment including a defined feature. According to the present invention, the turning length segment of each subsequent baluster is greater than the turning length segment of the previous baluster according to the equation of the riser height divided by the total number of balusters. Thus, each feature in the bottom length segment of each of the balusters align with the tread for each baluster. In the preferred embodiment, only four different baluster lengths are necessary for both two and three balusters per tread.
