A newel post is a wooden, vertical column positioned at the base of a staircase where the banister ends.
If a staircase is positioned against a wall on one side, there is usually only one newel post, while free-standing stair cases usually have two newel posts.
Newel posts typically range in height from 52 inches to 59 inches, though some may be as tall as 65 inches.
Newel post tops can be flat or rounded like a ball; the latter is referred to as a finial top. Newel posts are often elaborately decorated with carvings.
Newel posts serve as a means of support for the banister of a staircase. In some cases, newel posts also provide support to the risers or steps on the stairs or to a landing.
