Before ordering, please refer to the measuring chart below the video.

Measuring Overview and Guide

When installing a stair lift, the key is to begin with proper measurements. It really is very easy to measure for a stairlift. All you need is a tape measure. Take a general overview of your stairway layout and decide which side of the staircase the stairlift will be mounted on, when viewed from the bottom. The lift may be mounted on the banister side if desired. No wall is necessary as the stairlift mounts to the stair treads, not a wall. Be aware that the stairlift rail will overhang the top landing by approximately 6″ and meet the floor at the foot of the stairs approximately 14″ beyond the nose of the first step.

Start Here:

All measurements should be recorded in inches.


1. The most important measurement is marked as #1, Overall Length, on our guide below. This determines the length that we cut your rail for the lift. To obtain this measurement stand at the top of your stairs, extend your tap measure until it is laying on all the stair treads and the tip of the tape measure is touching the landing at the bottom of the steps.

2. Next measure from the edge of the top step to the edge of the first step. Mark this in block 2.

3. Next, measure the width of your staircase and enter the measurement into block 3, marked Staircase Width.

4. If there is a wall or a door at the bottom of the steps as illustrated as 4 on the diagram below, please measure from the bottom step to the wall.

5. The last three measurements (5,6,7) will enable us to preset the seat angle of your lift at the factory. Please measure each according to the diagram and enter the measurement results in at checkout under notes.
