When considering a stairlift, one of the most common concerns is how much space it will occupy, especially when it’s not in use. Most modern stairlifts are designed to fold away neatly, helping keep staircases clear and usable for others.
This page explains folded dimensions, space requirements, and what to expect in a typical home.
Key Takeaways
- Most stairlifts fold away when not in use
- Folded dimensions vary by model and staircase type
- Straight stairlifts usually take up less space than curved models
- Narrow staircases can often still accommodate a stairlift
- A professional survey confirms exact measurements
The Short Answer: How Much Space Does a Stairlift Need?
When folded, most stairlifts take up between 250mm and 350mm of space from the wall or bannister into the staircase. This leaves enough room for others to walk past in many homes.
Exact dimensions depend on the model, seat type, and rail position.
What Does “Folded Dimensions” Mean?
Folded dimensions refer to the amount of space a stairlift uses when:
- The seat is folded up
- The footrest is folded
- The armrests are folded
This is the stairlift’s smallest footprint and how it will sit when parked.
Typical Folded Dimensions (General Guide)
While measurements vary, typical folded sizes are:
- Straight stairlifts:
Approx. 250–300mm from wall or bannister - Curved stairlifts:
Approx. 300–350mm due to rail shape
These are general guidelines exact measurements depend on the specific installation.
How Stairlifts Save Space
Modern stairlifts are designed with space in mind and often include:
Folding Seats and Footrests
These reduce how far the stairlift protrudes when not in use.
Slimline Rails
Rails are mounted close to the stair treads to minimise obstruction.
Swivel and Parking Options
Some stairlifts can be parked at the top or bottom, away from walkways.
How Much Stair Width Is Needed?
Installers look at:
- Total stair width
- Remaining clear walking space once the stairlift is folded
- Safe access at the top and bottom of the stairs
Even narrow staircases can often accommodate a stairlift safely.
Straight vs Curved: Space Differences
| Feature | Straight Stairlift | Curved Stairlift |
|---|---|---|
| Rail type | Straight | Custom curved |
| Folded width | Usually slimmer | Slightly wider |
| Staircase impact | Minimal | Slightly more due to curves |
Both types are designed to minimise impact on daily use.
What About Top and Bottom Landings?
Space is also assessed at:
- The top landing for safe getting on and off
- The bottom landing to avoid blocking doorways or walkways
If space is limited, parking positions can often be adjusted.
How Do You Know What Will Fit?
The only way to know for sure is through a professional survey, which includes:
- Measuring the staircase
- Checking folded clearances
- Advising on suitable models
This ensures safety and comfort for everyone in the home.
