01. Stair handrails provide comfort while moving up and down a staircase.

Stair Handrail Sizes and Shapes
For handrails to be an effective component, it should neither be too small nor too large. Most common handrail sizes are:
01. Handrail Sizes -Circular Cross Section
The size of a handrail with circular cross sections must have a diameter ranging from 1 ¼ inches – 2 inches (30mm-50mm). A diagram of handrails with round cross sections is shown below:
02. Handrail Sizes-Non-Circular Cross Section
The size of handrails with non-circular cross sections must have perimeter dimensions ranging from 4 inches – 6 ¼ inches (100mm-155mm), and a maximum cross section dimension of 2 ¼ inches (55mm). A diagram of a handrail with non-circular cross sections of handrail is shown below:
03. Handrail Sizes- perimeter greater than 6 ¼ inches (155mm)
Handrails with a perimeter greater than 6 ¼ inches (155mm) must have a finger recessed area on both sides of its profile. The width of the handrail above the finger recess area shall range from 1/4 inch – 2 ¾ inches (6mm-70mm). The finger recess area must begin with a distance of ¾ inch (20mm) when measured vertically from the tallest part of the handrail profile, and it shall have a minimum of 5/16 inch(10mm) depth within, and 7/8 inch (22mm)depth below the widest portion of handrail profile. The diagrams of some handrails with a perimeter greater than 6 ¼ inches(155mm) are shown below:
Thus, all handrail profile should be amongst these types or with the profile having equivalent grasp-ability. Now let us look at the different types of handrail along with their pros and cons.

Modern Handrail Designs
Shown below are some modern handrail designs that are made up of various materials.
Method of fixing handrails
01. Fixing Handrails to Wall
Wall mounted handrails can be installed on any vertical surface or wall by using the appropriate fittings. While fixing handrails on walls, patrices are attached to the wall at appropriate intervals and are then fitted with handrails that are attached with the help of brackets at the respective points, making sure that connectors are marked centrally. The details of fixing handrails to walls are shown in the diagram below.
02. Fixing Handrail to Newel Post
a) Fixing Handrail to Newel Post with Bolt:
In this method, a handrail is attached to newel posts using bolts and then the handrail is secured by fixing it to a handrail plate. The details of fixing handrails to newel posts with bolts are shown in the diagram below.
b) Fixing handrail to Newel Post with Brackets:
In this method, a hole is drilled into the newel post for a stud, recessing nut and bracket. At first, the stud bracket is fixed at each end of the handrail using screws and then it is attached with newel posts. The handrail is then secure by applying a layer of PU adhesive at its end faces. The details of fixing handrails to newel posts with brackets are shown in the diagram below.
c) Fixing Handrail to Newel Post with Mortise and Tenon Joint:
This method is meant for wooden components. Here, the end of the handrail has an extension to form a tenon and part of the newel post is removed to form a mortise. Then they are both fixed together and glued to make it secure. The details of fixing handrails to newel posts by using bolt are shown in the diagram below.
After learning about stair handrails, it is important to note that they must be designed by keeping the mandatory regulations, as depicted in the building codes for handrails on stairs, in mind.
