Upon selecting the body size of a newel post, care should be taken not to over-indulge the stairway with an inordinately oversized newel. A rule of thumb to follow is to size the stairway’s starting newel to a maximum of one-eighth of the width of the stairway. Include the starting step in the calculation only if the newel is positioned on the outboard edge of the starting step. Subsequent newels may be, and should be, downsized if the starting newel has been sized to the maximum.
