Parts of a staircase. Balusters are the vertical posts that support the handrail. Balustrade include the balusters, handrail and newel posts. The landing is a break in a set of stairs. Newel posts are a vertical support post at the end of a handrail. The riser is the vertical section of a step from one tread to the next and the rounded front edge of the riser that protrudes beyond the stair is the nosing. A tread is the horizontal part of a step and the surface you walk on. The height of the whole staircase is called the total rise. The stringer is the structural foundation that risers and treads are nailed to.
Configurations of staircases. The most common and economical configuration is the straight-run. U and L shaped work for in difficult design situations and take up more square footage because they require a landing. In extremely tight spaces a l shaped winder is used, the winder replaces the landing with triangular steps. The spiral is the last resort for a staircase in tight floor plans, home buyers are not fond of this style.
