Choosing the right wheelchair size is essential for comfort, safety, and mobility. A well-fitted chair makes daily life easier, prevents strain, and supports good posture. Here’s a step-by-step guide to finding the right fit.
1. Seat width
How to measure: While seated, measure the widest part of your hips or thighs.
Add a few centimetres or 1 - 2 inches: This gives enough room for comfortable movement, seasonal clothing, and prevents rubbing.
Too narrow causes pressure, too wide makes it harder to self-propel and use the armrests.
2. Seat depth
How to measure: Sit upright and measure from the back of your hip (or back of the seat) to the crease behind your knee.
Subtract a few centimetres or 1 - 2 inches: This ensures the seat doesn’t press into the back of your knees.
Correct seat depth supports your thighs evenly and maintains good circulation.
3. Seat-to-floor height
How to measure: Your feet should rest flat on the footrests, with ankles and knees at about a 90° angle.
This helps with proper positioning. Some users may adjust the height for foot propulsion if they move the chair with their feet.
Other key measurements
Overall wheelchair width: Check your doorways and hallways to make sure the chair can pass through comfortably.
Armrest height: Should support your arms without forcing shoulders up or down.
Weight capacity: Confirm the chair can safely support your weight.
Footrests: Adjust so your legs are supported, not dangling or forced too high.
Seek professional advice - Every person’s body and lifestyle are different. For the best results, especially if you have complex needs, consult a healthcare professional or occupational therapist. They can recommend the most suitable wheelchair to support your posture, comfort, and independence.
