Is measuring for a staircase important – or can you go without one?

Staircases require at least one handrail if the following applies:

  • The stairs are less than 1m wide: provide a handrail on one or both sides.

  • The stairs are wider than 1m: provide a handrail on both sides.

Handrails are important components of a staircase since they offer stability and protection to the person who is climbing up the stairs – particularly if you have children in your home.

A guide to stair handrail length and height requirements

What length should a handrail be, and how can you make sure a handrail is the right 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.

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.
