Most newels are three to three and a half feet in height.
Pegged newel posts are ideal if you can t easily remove the existing newel base from your staircase but want to update the look of your newel.
Before doing newel post placement determine how the newel post will attach to a handrail according to code for standard handrail height.

The handrail height determines what height your newel post will be.

Box newels though are typically five to five and a half feet tall.
