The handrail height determines what height your newel post will be.
Best height off floor for knewl post.
Calculating the newel post height is the first step in newel post installation.
Before doing newel post placement determine how the newel post will attach to a handrail according to code for standard handrail height.
A newel post is always a fixed length usually 750mm 850mm long excluding the peg.
Finally my personally recommended method of newel post installation unless you mount the post into the floor.
Box newels though are typically five to five and a half feet tall.
Most newels are three to three and a half feet in height.
The two most common scenarios are floor level posts and posts at the start of a stair.
So my personal favorite is the hanger bolt.
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.
The newel base makes up the remainder of the height of the newel post.
Mounting the post through the floor is by far the strongest most durable and probably the best method but the difficulty is such that it is rarely if ever required.
Designs for newel posts are governed by the international residential code irc which says handrail heights must be between 34 and 38 inches.
