How to Measure Stairs for a Stairlift for a Perfect Fit- A Guide!

Installing a stairlift can improve mobility, especially for seniors or those with limited movement. A proper fit ensures safety and functionality, but achieving this starts with accurate measurements. While a professional inspection is necessary for final installation, taking preliminary measurements helps estimate costs and determine feasibility before scheduling an expert visit.

This stairlift measurement guide covers the essential steps for measuring straight and curved staircases, the tools needed, and key considerations for a smooth installation. Whether you’re buying a stairlift or exploring options, understanding these basic tips will help you communicate effectively with providers and ensure a smooth process. Let’s discuss how to measure stairs for a stairlift in detail.

Why Measure Your Stairs Before Buying a Stairlift?

Before scheduling a professional assessment, taking initial measurements offers several advantages:

  • Cost Estimation: Stairlift prices vary based on staircase length, width, and complexity. Basic measurements help gauge potential expenses.
  • Feasibility Check: Some staircases may require modifications or specialized models. Early measurements identify potential installation challenges.
  • Faster Consultations: Having dimensions ready allows for quicker discussions with providers before an in-home assessment.

While DIY measurements are helpful, they should never replace a professional evaluation. Experts account for structural nuances that homeowners might miss.

What Will You Need?

Measuring a staircase doesn’t require specialized tools, but accuracy is crucial. Here’s what’s needed:

  • A sturdy metal tape measure (avoid fabric or floppy tapes, as they can lead to inaccuracies)
  • A notepad and pen to record measurements
  • A second person (helpful for holding the tape measure steady, especially on longer staircases)

[Note: Always double-check measurements to ensure precision before finalizing any details.]

Step-by-Step Guide to Measuring for a Stairlift

Measuring for a stairlift requires precision to ensure a proper fit and safe operation. Below is the best way to measure stairs for a stairlift installation, whether straight or curved.

Step 1: Determine the Stairlift’s Position (Left or Right Side)

The first decision is which side of the staircase the stairlift should be installed on. Consider the following:

  • Open vs. walled staircases: If one side of the staircase is open (without a wall), the safest option is usually the walled side for stability.
  • Two-walled staircases: If both sides have walls, choose the side most convenient for the user, typically the side closest to where they enter or exit the stairs.
  • Obstructions: Check for doors, radiators, or furniture that might interfere with the stairlift’s path.

Step 2: Measure the Staircase Length

The length of the staircase determines the required track length for the stairlift. To measure the stairs for a stairlift accurately:

  • Start at the top step: Place the tape measure at the edge of the top tread (the horizontal part of the step).
  • Extend to the bottom: Run the tape measure down the stairs, ensuring it follows the contour of each step and touches every tread.
  • Include the landing area: Extend the measurement past the bottom step to account for where the stairlift will park when not in use.

Having an extra person hold the tape measure in place can prevent errors caused by slipping or misalignment.

Step 3: Measure the Staircase Width

The width of the staircase affects whether a stairlift can be installed comfortably. Follow these home stairlift measurement tips:

  • Find the narrowest point: Some staircases taper or have protruding moldings that reduce clearance.
  • Measure from skirting board to skirting board: Avoid measuring wall-to-wall, as skirting boards (baseboards) are the true boundaries.
  • Check minimum width requirements: Most stairlifts need at least 28 inches (71 cm) of clear space, but compact models may fit narrower staircases.

Step 4: Check Parking Space at the Top and Bottom

A stairlift needs adequate clearance at both ends to park safely and allow easy boarding.

  • At the bottom: Measure from the bottom step’s riser (the vertical part) to the nearest obstacle (e.g., a door, radiator, or wall).
  • At the top: Ensure there’s enough space for the chair to fold and for the user to step off comfortably.

Most stairlifts require at least 24-30 inches (61-76 cm) of clearance for safe operation.

How to Measure a Curved or Multi-Turn Staircase?

Curved staircases, including those with landings or spiral designs, present unique challenges for stairlift installation. Unlike straight stairlifts, which use standardized tracks, curved models require custom fabrication based on precise measurements. Due to the complexity of angles, turns, and potential obstructions, professional assessment is strongly recommended. 

Homeowners can assist the process by taking reference photos and noting the number of steps and turns, but an expert survey is necessary for accurate design and installation. Attempting DIY measurements on curved stairs often leads to errors, making professional involvement essential.

Common Mistakes to Avoid When You Measure Stairs for a Stairlift Installation

Several common errors can lead to incorrect assessments when measuring for a stairlift. Using a flexible or cloth tape measure can result in inaccurate readings, so a rigid metal tape is always preferred. Measuring wall-to-wall instead of skirting-to-skirting may overlook obstructions that reduce usable space. 

Overlooking obstacles like light fixtures, radiators, or low ceilings can cause later installation problems. Finally, forgetting to verify clearance at both ends of the staircase may result in a stairlift that doesn’t park or operate safely. Double-checking all dimensions helps avoid these pitfalls.

Next Steps to Follow After You Measure Stairs for a Stairlift

Once measurements are complete, the next step is to consult with a stairlift provider. Sharing the recorded dimensions allows suppliers to offer preliminary advice on suitable models and estimated costs. A professional inspection will still be required for precise planning, but having initial measurements speeds up the process. 

Comparing quotes from multiple providers ensures the best price, features, and service combination. With this information, homeowners can move forward confidently, knowing their stairlift will be tailored to their staircase’s exact specifications.

Conclusion

Accurately measuring your stairs for a stairlift is a crucial step in ensuring a safe, functional, and cost-effective installation. Whether dealing with straight or curved staircases, taking precise measurements of length, width, and clearance helps estimate costs, assess feasibility, and streamline consultations with providers. While DIY measurements provide a helpful starting point, they should always be followed by a professional assessment to avoid common mistakes.
