Yes stairlifts can often be fitted on narrow stairs, but it depends on the staircase width, layout, and the type of stairlift used.
Modern stairlifts are designed to work in surprisingly tight spaces, and many homes with narrow staircases can still be adapted safely.
A professional survey is the key to confirming suitability.
Key Takeaways
- Many narrow staircases can accommodate a stairlift
- Minimum width requirements vary by model
- Slimline and folding designs improve suitability
- Safety and clear access for others must be considered
- A survey determines what will work
How Narrow Is Too Narrow for a Stairlift?
There is no single minimum width that applies to every stairlift.
In general:
- Many stairlifts can be fitted on stairs around 700–750mm wide
- Some slimline models work on even narrower staircases
- The key measurement is usable width, not total stair width
Clearance must remain for safe use and, in some cases, for others to pass.
What Makes Stairlifts Work on Narrow Stairs?
Modern stairlifts include features designed for tight spaces:
- Slimline seats and footrests
- Folding arms, seats, and footplates
- Compact rails mounted close to the steps
- Swivel seats for safe dismounting at the top
These features reduce obstruction when the stairlift is not in use.
Does Stair Shape Matter?
Yes.
Narrow stairs can still be suitable if:
- The staircase is straight
- The steps are consistent
- There is enough headroom
Curved staircases or winders may reduce available space and require bespoke solutions.
Can Other People Still Use the Stairs?
Often, yes.
When folded:
- Many stairlifts leave sufficient walking space
- Slimline designs minimise obstruction
However, in very narrow staircases, the stairlift may partially block access, which should be considered during the survey.
What About Safety on Narrow Stairs?
Safety is the priority.
A stairlift must:
- Allow safe seating and movement
- Provide clear footrest positioning
- Leave safe access at the top and bottom landings
If safety clearance can’t be met, installation won’t be recommended.
Are Narrow Stairs More Suitable for Straight Stairlifts?
Yes.
Straight stairlifts are:
- More compact
- Easier to fit on narrow stairs
- More readily available in slimline models
Curved stairlifts usually require more space due to rail design.
How Is Suitability Confirmed?
A professional survey measures:
- Stair width at multiple points
- Step height and depth
- Headroom and landings
- Clearance when folded
This ensures the stairlift fits safely and comfortably.
Final Verdict: Can You Fit a Stairlift on Narrow Stairs?
Yes many narrow staircases can safely accommodate a stairlift.
With modern slimline designs and folding features, even tight staircases can often be adapted, provided safety and access requirements are met.
A professional survey is essential to determine the best solution.
