What Is the Minimum Stair Width Required for a Stairlift?
If you’re considering a stairlift but have a narrow staircase, you may be wondering whether it’s even possible to install one. The good news is that modern stairlift designs—especially compact and slimline models—are specifically built to work in tight spaces. But just how narrow can your staircase be?
In this article, we’ll break down the minimum stair width required for a stairlift, explore what factors influence installation, and share how certain models like the Bespoke Synergy and Infinity make safe and comfortable stairlift access possible, even on tight staircases.
What’s the Minimum Stair Width for a Stairlift?
The minimum staircase width required for a stairlift is generally between 27 and 29 inches (68–74 cm). However, this can vary depending on several factors, including the specific stairlift model, the user’s size and mobility requirements, local building regulations, and whether the staircase is straight, curved, or spiral.
Straight staircases typically require less space than curved ones, and certain narrow stairlift models can be installed on staircases as narrow as 24 to 25 inches, depending on the layout and the user’s needs.
Factors That Affect Stairlift Width Requirements
1. Stairlift Model Design: Slimline models like the Bespoke Synergy or Infinity have foldable seats, armrests, and footrests, which reduce the profile when not in use.
2. User Needs: Larger users or those needing assistance from a caregiver may require wider clearances for safe use.
3. Track Type: Single rail vs. twin rail systems can affect how much space is taken up on the stairs. Curved stairlifts often require a slightly wider staircase due to custom bends.
4. Obstacles Near the Stairs: Radiators, handrails, door frames, and tight landings can all reduce usable space. These can be worked around with custom modifications or offset rail designs.
