What are the standard stairlift dimensions?

Stairlifts come in different shapes and sizes, but the typical stairlift width is between 64 cm and 77 cm. The exact dimensions vary by model and seat choice, but this is a reasonable frame of reference for those looking to install a stairlift at home.

The width quoted above includes not only the chair itself but also the full width of the stairlift when connected to the rail. It’s also important to consider landing space and whether your stairlift will have enough room to swivel for a safe exit.

Let’s look at the dimensions for some of the different stairlift models available from Companion Stairlifts. These are just examples, as your choice of seat type can impact the model’s width.

Minimum stair width for a stairlift installation

Typically, your staircase will need to have a minimum width of 71 cm to comfortably and safely accommodate a stairlift. However, this varies by model and the type of stairlift you require. For example, some curved models may require more room.

However, there is usually a solution for every type of stairs, even ones that are very narrow. With perch seat options, slimline rails, and custom features, everyone who needs a stairlift can find something that works for them.

Stairlift options for narrow staircases

Companion Freecurve stairlift

There is a range of excellent options available for homes with narrow stairs. Models such as the Companion 1100 for straight stairs and the Companion Freecurve for curved stairs provide compact and slimline solutions.

There are also optional extras, such as a hinge track system, that allow the rail to be folded away at the top or bottom of the stairs. Some users also opt for perch seats, which take up less space and are more comfortable for those who find bending their knees uncomfortable.
