SpinTip: Stair Lift Measuring Guide

Measuring your stairway correctly is essential to ensuring that your new stair lift will install easily and function safely and properly. Please follow the instructions below carefully.

Step 1: Determine Mount Side 

Determine Stair Lift Mount SideMount Side: From the bottom of your staircase looking up, determine on which side you want the lift installed. Because the lift mounts to the stairs and not the wall, you may choose either side.

Step 2: Measure for Length of Track Measure for Length of Stair Lift

Measurement A - Top to Bottom: Stand at the top of your stairs and extend your tape measure down the staircase. The tape measure should lightly touch each stair tread and the tip should touch the landing at the bottom of the steps. The measurement should be from the front edge (nose) of the top landing to the floor at the bottom landing.

Measurement B - Top to First Step:  Measure from the front edge (nose) at the top of the landing to the front edge (nose) of the first step.


Step 3: Measure the Stair Tread & Rise 

Measure the Tread & Rise for the Stair Lift
Measurement C - Stair Tread Length:
Measure the tread of a stair from front edge (nose) of a stair to back.

Measurement D - Stair Rise Height: Measure the rise of a stair by measuring the length from the front edge (nose) of one step straight down to the next tread.

Number of Risers: Count the number of stair risers on your staircase.


Step 4: Measure Top & Bottom Obstruction Distances
