When buying a handrail, there are many factors you need to consider to ensure it’s the right one for your staircase. This includes the aesthetic you’re looking for, the material, durability and the style you desire.

Choosing the correct handrail length

To determine the correct handrail length, you can hook a tape measure onto the bottom stair nose and measure up to the top of the staircase. A staircase handrail should run the entire length of the stairs to make sure it is safe and code complaint. Handrails are often sold in set lengths of 1.8m, 2.4m, 3.6m and 4.2m. Choose the best length that fits your staircase measurements.

Your handrail should run the full length of the staircase to ensure it is a secure and supportive as possible.

How high should a stair handrail be mounted?

According to Part K Building Regulations - in a domestic property, the top of the handrail must be no lower than 900mm from the nosing of the stair tread to the top of the handrail. This 900mm height rule also applies to handrails on landings.

Your handrail should be fitted at a height between 900mm and 1000mm from the pitch line of the stairs, or the floor for landings. The pitch line is a virtual line that sits on top of the nosing at the edge of the stair treads. You can find out more about measuring the correct handrail height here.

What is a handrail groove, and how are grooved handrails used?

There are two main types of handrails available for your staircase - grooved and ungrooved. Grooved handrails are designed to be fully integrated on top of spindles, or glass panels. Ungrooved handrails, on the other hand, are designed to be fitted to metal or wooden spindles, or to glass panels via brackets and clamps.

Uses for grooved handrails

Grooved handrails with wide, shallow channels are designed to be used primarily with wooden spindles. The groove must be the same width as the spindles you intend to use to achieve a secure fit. The groove runs along the full length of the handrail so that spindles can be spaced as often as necessary. Timber infill, also known as spacer or filler, is normally provided with these types of grooved handrails. It is worth noting that although Jackson Woodturner's handrails and base rails will come with infill, you will need to buy silicone separately.

Metal spindles can also be connected to grooved handrails designed for metal, which have a smaller groove.

On the other hand, glass grooved handrails are designed to be used alongside glass panels. They have a narrow, deep channel running along the full length of the handrail into which the glass panel slots. Usually, clear silicone is used to help secure the glass in place. The grooved handrail eliminates the need for any metal brackets to connect the glass panels to the handrail.

Choosing the right size groove

If using a grooved handrail with glass panels, check the width of the glass panels and look for a handrail with a groove of the same depth. For example, our 8mm grooved handrails are compatible with the following glass panels, which are 8mm thick:

Our Immix glass panels are also 8mm thick, but they should only be used with other Immix stair parts to ensure a secure fit and unified finish. You should therefore choose one of our Immix Oak Handrails which are available in 2.4m, 3.6m and 4.2m.

When using grooved handrails with wooden spindles, check the width of your spindles and choose a handrail with a groove of the same width. Our 32mm grooved handrails fit all of our 32mm spindles, including the Forge range of brushed nickel spindles. Our 41mm grooved handrails are compatible with our 41mm wooden spindles.

Fitting wall-mounted handrails

Fitting a pigs ear handrail

Aside from their simple appearance, flexibility and cost, pig's ear handrails are a very popular choice of handrail because of their affordability and versatility. One of their key advantages is that they do not need brackets to be attached to the wall, which saves a lot of space.

Mopstick handrails are attached to the wall with the help of wall handrail brackets, making them a popular option for buyers searching for a handrail that might be more ornamental.

When installing a mopstick handrail, you'll need to select some handrail brackets that are complementary to your handrail's style and finish. Mopstick handrails also often require accessories such as end caps and wall patrices – so pigs ear handrails can save you time and money in this sense.

They can screw directly into the wall, using cross grain pellets to fill the holes and hide the screws. Before installing a handrail, you should measure the length of your staircase to check the size you require.

Fitting a mopstick handrail


Both mopstick and pig’s ear handrails are both fitted onto the wall, but in different ways. Mopstick handrails require brackets and patrices that work with the handrail to attach to the wall.

How you fit your handrail to the wall bracket all depends on the wall bracket you choose. Brackets like this wall-mounted chrome option below allow the mopstick handrail to slide into it easily before being attached to the wall. Others, such as this brushed nickel wall bracket, will need to be screwed into both the handrail and the wall patrice.

It is important to fit your handrail in the correct position to ensure it is in the most optimal height for your staircase. You should measure the length of your staircase to determine the exact length of handrail that you’ll need. You can find out more in our handrails guide here.
