Stairlifts for narrow stairs
Narrow stairs rarely rule out a stairlift: Age UK Mobility says a home's main staircase is very unlikely to be too narrow for a compact model. The questions are which model, and how much width is left for others.
Updated Oct 21, 2026
How much width you need
| Stair width | Options |
|---|---|
| 66–74 cm | Compact seated models (Acorn states 66 cm for its straight 130) |
| 60–66 cm | Slim seated or perch models, after a survey |
| under 60 cm | Standing lift, a stair climber, or a home lift |
Getting the most from a narrow staircase
- Slim rail and folding seat: the folded width decides how much room others keep.
- Perch seat: narrower than a full seat, for riders who can lean.
- Rail on the right side: put the rail on the side that leaves the handrail free.
- Remove obstacles: a radiator or a deep window sill can sometimes be moved.

When it really doesn't fit
A home lift needs a spot in the house instead of the stairs, and a stair climber needs no installation at all.
Frequently asked questions
What is the narrowest stairlift?
Makers publish the folded width and minimum stair width of each model on their spec sheets; compare them on our model pages and confirm with a survey.
Will the stairs still be usable by others?
Yes, with the seat folded; on very narrow stairs choose a slim model and the side that keeps the handrail free.
