Finding the Right Stairlift to Fit in Your Home

For those considering a stairlift to address their mobility struggles, one of the most common concerns is how the stairlift will fit on their stairs and in their home. So, is a stairlift feasible? Let’s explore some stairlift dimensions and specifications to find out!

Stairlifts – A Practical Mobility Solution

Before we get started, let’s make sure we’re all on the same page. When we talk about stairlifts, we’re talking about a chair on a motorized chassis, riding along a metal rail that is fixed to the stair treads. These are not lift chairs, vertical platform lifts or home elevators. They cannot carry a wheelchair up the stairs, nor transport multiple riders at the same time. Stairlifts are designed for a single, seated user, bringing them up or down stairs with the gentle push of a button.

Types of Stairlifts and Where They Can be Installed

Stairlifts can be fitted onto straight, curved or outdoor staircases and come with a variety of options to suit the needs of the user. Straight stairlifts are mounted to a single, straight rail, cut to the precise length of the staircase, while Curved stairlifts are either modular or custom-made for the bends and turns of a curved or multi-flight staircase. Outdoor stairlifts are of a similar design, but weather-proofed to withstand the elements. Let’s take a look at some stairlift dimensions and specifications.

Stairlift Specifications

Stairlift Maximum Weight Capacity

The weight capacity of a stairlift depends on the model you choose. Typically, straight stairlifts can carry up to 160 kg, while curved and outdoor models have a weight limit of 135 kg.

Stairlift Speed

Regardless of model, Stannah stairlifts all operate at 5 meter per minute. Taking you up and downstairs at a safe and steady pace.

Electrical Requirements

Whether straight or curved, indoor or outdoor, stairlifts run on battery power. The batteries are charged by a regular 110-Volt outlet, near the top or bottom of the stairs. In the case of an outdoor stairlift, you will still need access to an indoor outlet, nearby. The appropriate outlet is usually chosen during a free stair survey, so you don’t have to worry about that, until someone comes to see your stairs. If you’re concerned about your electric bill, don’t be. The stairlift uses about as much electricity as your coffee pot.

How wide do stairs have to be for a stair lift?

As mentioned above, the minimum stair width depends on the model you choose and any obstructions on the staircase. Generally speaking, straight stairlifts require a 70 cm wide staircase, while curved stairlifts need around 75 cm (depending on the shape of your stairs). It is important to note that these measurements are from the furthest obstruction, meaning that handrails, moldings and other obstructions can reduce your staircase width. In some cases, handrails might need to be removed.

Rail Position

The position of a stairlift rail depends on the type of staircase you have and the model you choose. On most straight staircases, the outside edge of the rail is about 15 cm from the wall (or furthest obstruction). Rail-to-wall measurements for curved models will vary depending on the shape of your stairs and the turns it needs to make, but most straight sections are usually about 15 cm from the wall.

How do you measure for a stair lift?

Stairlift measurements are taken during a no-obligation stair survey, where a Stannah stairlift specialist will visit your home in order to determine which model and options you need.

Straight Stairlift Measurements

Straight stairs are measured for length and width, using a standard tape measure. Special care is taken to identify potential obstructions, such as a handrail or limited head clearance near the top of the stairs. Doors at the top landing or near the bottom are also taken into consideration, with the optional retractable rail providing a solution in most of these cases. The stairlift specialist will make sure that there is sufficient space for the chair to swivel at the top of the stairs, so you can get off safely.

Curved Stairlift Measurements

When measuring stairs that turn, Stannah’s stairlift specialists use a photo measuring system that utilizes markers on the stairs to develop accurate specs for the staircase. From there, the specialist will check the stairs for obstructions, just like they would for a straight unit, before sending the photos and a detailed drawing off to our rail designers. With their custom rails, curved stairlifts have the added benefit of offering a variety of starts and finishes to accommodate the specifics of your home. As a result, a curved stairlift can start around the corner from the stairs and continue onto the top landing, making it safer and easier to get on and off.
