UK Stairlift Specifications & Dimensions: Models Compared

Last updated: 22 June 2026 · Manufacturer specifications, linked at point of use. Free to cite with attribution.

This page compares the published specifications of leading UK stairlift models, alongside the typical dimensions you need to plan an installation. All figures are manufacturer specifications; always confirm current details and your own staircase measurements with an installer before buying.

Typical UK stairlift dimensions at a glance

The space a stairlift needs is governed more by the width of the seat and footrest in use than by the rail itself, which mounts to the stair treads close to one wall. Folding the seat, arms and footrest when the lift is not in use returns most of the staircase to other users. The narrowest models, such as the Handicare Simplicity 950, fit staircases from about 655 mm wide (Stannah stairlift dimensions; Minivator 950 specification).

Weight capacities are standard-model manufacturer figures; some models offer heavy-duty variants with higher limits. Curved-rail dimensions are bespoke to each staircase, so no single minimum width applies.

How to check a stairlift will fit

Measure the narrowest point of your staircase (often where a handrail or skirting board projects), the total run of the stairs, and any door or hallway at the top and bottom that the rail might overhang. A hinged or folding rail can resolve overrun at the bottom of the stairs. For turns, landings or spiral stairs you will need a curved model with a custom rail. See our guides to narrow stairs, heavy-duty and curved stairlifts, and our stairlift glossary.

FAQ

What is the minimum stair width for a stairlift?

Slim models such as the Handicare Simplicity 950 fit staircases from about 655 mm wide. Most standard models need a little more. The seat and footrest, not the rail, set the real space requirement, and these fold away when the lift is not in use.

What weight can a stairlift hold?

Standard UK models typically carry 18 to 25 stone (around 115 to 160 kg). Heavy-duty or bariatric models extend higher. Always check the safe working load of the specific model.

Do curved stairlifts need wider stairs than straight ones?

Not necessarily. Curved rails are made to measure for each staircase, so fit depends on the individual stairs rather than a fixed minimum width. An on-site survey is required for any curved installation.
