How to Measure Your Stairs for an Initial Stairlift Estimate
You only need a tape measure and ten minutes. These measurements help you get a more accurate initial estimate. The installer will always take precise measurements at the home survey before anything is ordered.

The four measurements to take
Staircase length
Measure in a straight line from the nose (front edge) of the top step down to the floor at the bottom, along the slope. Note the number of steps.
Clear width
Measure across the stairs at the narrowest point, from wall (or skirting) to the inside of the banister or handrail.
Bottom clearance
From the bottom step, measure how far it is to the nearest door, wall or obstruction in front. The rail usually extends a little past the bottom step.
Top landing
Measure the depth of the landing from the top step to the nearest wall or door, so there is space to get off safely.
Write down whether the stairs turn at any point. If they do, you will need a curved stairlift, which must be surveyed professionally.
Note any obstructions
- Radiators on the stairs or landings.
- Doors opening towards the stairs at the top or bottom.
- Window sills or low ceilings above the stairs.
- Newel posts and handrails.
- The nearest power socket.
