Getting approved for a wheelchair is a huge step in a person's independence, but the fit of the wheelchair is just as important. A well-fitted wheelchair is crucial to health and long-term comfort. Find out why wheelchair fitting is important and key measures needed for a perfect fit here.

Why Do I Need A Wheelchair Fitting?

Just like glasses or medication, a wheelchair isn’t a one-size-fits-all solution. It’s tailored specifically to your life and needs. While you might think about getting a wheelchair without professional help, it could cause more harm than good. Letting an assistive technology professional measure you ensures your wheelchair will fit properly and feel natural.

Benefits of a Properly Fitting Wheelchair

  • Improved mobility. Wheelchairs allow freedom of movement for the user that they may not experience otherwise, leading to a more active lifestyle.
  • Independence. People who have difficulty balancing when they walk may gradually settle into a sedentary and secluded lifestyle to avoid feeling exposed or potentially injured. Wheelchairs may provide independence to return to hobbies, activities, and social events.
  • Injury prevention. Beyond preventing injuries due to balance and instability while walking, a well-fitting wheelchair can minimize injuries when self-propelling and prevent pressure sores and blood clots from sitting.
  • Comfort. A custom wheelchair provides comfortable seating and good back support to improve posture. This improves breathing, swallowing, and overall discomfort and pain management.

Disadvantages of a Poorly Fitted Wheelchair

You aren't just missing out on advantages by using a poorly fitting chair; you're potentially causing significant pain and damage, including:

  • Poor posture. Placing unnecessary stress on your spine, joints, and organs tires you faster and weakens your body overall.
  • Breathing issues. You may be limiting your respiratory system by being confined to a smaller chair than your body needs.
  • Hip and pelvic problems. Some wheelchairs are meant for transport or short stints for the occupant. These transport chairs are not meant to be sat in for as long as some people need them, which leads to hip and pelvic issues.
  • Overall pain and discomfort. Just like wearing ill-fitting shoes, using a wheelchair that’s not designed for your specific needs and activities can cause pain and discomfort.
  • Pressure ulcers and sores. Wheelchairs have certain ergonomics that prevent pressure sores and ulcers, provided the chair is fitted to you in the first place.

A poorly fitting chair won't last as long as a custom one because there is more potential for uneven wear and tear, leading to higher repair or replacement costs.

The Golden Ratio for Wheelchairs

The 90-90-90 rule, also known as the “Golden Ratio,” is a standard guideline for wheelchair users. It suggests that the user’s hips, knees, and ankles should all be at 90-degree angles when seated. While this rule may not apply perfectly to every individual, it serves as a helpful starting point for finding the right fit.

What Measurements Do I Need to Be Fitted?

While these are the measurements you need to be fitted, other considerations, such as height and weight, factor into how the chair fits. Measure yourself to know what chair you need, but ensure you speak with an expert and get their professional measurements and input.

Seat Width and Depth

Seat Width

Measure your hips from one side to the other in a straight line. Add two inches to this measurement for your proper seat width.

Seat Depth

Measure from the back of your hip to the back of the knee while seated. Subtract one inch from this measurement for your proper seat depth.

Arm Type and Height

Full-Length Wheelchair Arms

These are best for people who will frequently use stand-up pivot transfers. Full-length arms provide the support needed to push themselves up to stand.

Desk-Length Wheelchair Arms

These are best for people sitting at a table or desk in a wheelchair. The shorter arms allow the chair to be closer to the table's edge.

Arm Height

This can vary based on preferences. Measure from your elbow to the seat of the chair while holding your arms up with elbows bent at a 90° angle. When available, adjustable wheelchair arms are recommended.

Back Height

While sitting in a chair, measure the distance from your collarbone to your seat. Doctors can prescribe higher backrests or reclining backrests to distribute weight more evenly.

Wheelchair Seat Height

If you need to propel yourself with your feet while in your chair, measure the distance from the back of the knee to the heel. Proper seat height should allow you to reach the floor with heels, if necessary.
