Electric wheelchairs are not one-size-fits-all, so a proper fitting is required to ensure the user's comfort and independence. When measuring for an electric wheelchair, it is important to consider the width, length, and height of the chair in relation to the user's body measurements. The width of the chair should allow the user to fit through doorways and move comfortably in different environments, while the length and height should be adjusted for the user's leg and back support needs. Seat depth, height, and armrest height are also crucial measurements to ensure the user can sit comfortably and reach the floor with their feet. During the fitting process, the user should be seated on a firm, flat surface, and measurements should be taken using a hard measuring tape or calipers to ensure accuracy.
| Characteristics | Values |
|---|---|
| Wheelchair width | Balances well in different settings and meets various user needs. |
| Seat depth | Measured from the user's posterior buttock, along the lateral thigh to the popliteal fold with your palm horizontal to the seat. |
| Seat height | Determined by the height of the individual and whether the wheelchair is self-propelled. |
| Armrest height | Should allow the user to sit erect, with level shoulders when bearing weight on the forearms as they rest on the armrests. |
| Backrest height | Depends on the needs of the user. Wheelchair users who push themselves need a backrest that allows their shoulders to move freely. |
| Footrest length | The footplate must be about 1 to 2 inches off the ground to permit adequate ground clearance. |

What You'll Learn
Seat depth and height
Seat depth is typically measured from the base of the spine, along the back of the thigh, stopping at the back of the knee. This measurement ensures that there is enough space between the front edge of the seat and the back of the user's knee—approximately two inches or the width of three to four fingers. This space is essential to avoid pressure on the knees and enhance circulation.
For individuals with contracted knee joints, it is crucial to ensure that the calf does not touch the seat cushion or the underlying frame structure. Additionally, for those with heavier weights, the seat depth may need to be adjusted to accommodate the protrusion of the buttock area towards the back.
Seat height, on the other hand, is determined by the user's height and whether they will be self-propelling the wheelchair or using leg supports. A taller user will generally require a higher seat. If the user intends to propel the chair with their feet, the seat height should be slightly lower than their leg length, allowing them to reach the floor with their heels. In contrast, if the user will be using leg supports, the seat height should be higher.
The presence of a footrest also influences seat height measurements. If the user requires a footrest, it should be factored into the calculations. The footrest should be positioned approximately two inches off the ground to provide adequate ground clearance and manoeuvrability.
Overall, accurate measurements of seat depth and height are vital to ensure the user's comfort, stability, and ease of use.

Width for doorways
When choosing an electric wheelchair, it is essential to consider the width of the doorways in your home or any other indoor spaces you frequent. The wheelchair should fit through doorways without requiring any home adjustments, ensuring your space remains accessible and welcoming.
The average electric wheelchair is about 26 inches wide, and full-size power wheelchairs typically range between 30 and 34 inches in width. When measuring doorways, it is crucial to consider the wiggle room on each side of the wheelchair. Therefore, the doorway's width should exceed the wheelchair width by several inches.
Standard electric power wheelchairs offer seat widths ranging from 16 to 20 inches, making them a compact option for daily use. Bariatric models, on the other hand, offer wider seats exceeding 20 inches to accommodate various body sizes and provide better stability for heavier users. When selecting a wheelchair, it is essential to consider not only the width but also the seat depth, height, and other features that impact your comfort and mobility.
To ensure a proper fit, it is recommended to seek a professional fitting with an ATP (Assistive Technology Professional) therapist. They will guide you in choosing the right wheelchair and teach you how to use and maintain it. During the fitting, measurements are taken while you are seated on a firm, flat surface, maintaining the "ideal" posture the therapist is trying to achieve. Accurate measurements are crucial for selecting the correctly sized equipment and enhancing your independence, comfort, and quality of life.

Armrest height
To calculate the ideal armrest height, measure from the top of the seat to the user's elbow. Before taking this measurement, ensure the individual is sitting with their shoulders level and their weight distributed through the forearm resting on the armrest. The armrests should be high enough to support the elbows when they are bent at a 90-degree angle.
Another way to measure armrest height is to measure from the sitting surface to the bent elbow. The ideal height is typically considered to be around 225mm to ensure ergonomic support.
It is important to note that the height of the seat cushion will also add to the overall height of the armrest. Therefore, it is recommended to take this into consideration when measuring for the armrest height. Additionally, for users who will be performing stand-up pivot transfers, consider full-length armrests, while the standard desk-length armrests are suitable for everyday use and allow users to get closer to tables and desks.

Backrest height
The backrest height of an electric wheelchair is a crucial measurement that depends on the user's needs and abilities. It is essential to ensure the user's comfort and proper positioning, preventing posture problems, cramped muscles, and other issues that can arise from an improperly fitted wheelchair.
To calculate the backrest height, it is recommended to measure from the top of the seat up the user's spine. The user should be sitting as upright as possible, and the measurement should end at the desired height for the top of the backrest. This measurement is typically four inches below the axilla (just below the shoulder joint) for self-propelled wheelchair users. However, if the user propels the wheelchair using their feet and does not use a footrest, this step may be skipped.
The height of the backrest is determined by the user's needs. Those who push themselves in the wheelchair require a backrest that allows their shoulders to move freely without restriction or discomfort. In this case, a lower backrest may be preferred to provide more arm movement. On the other hand, individuals with difficulty sitting upright may benefit from a higher backrest that provides more support to the spine.
For users with postural conditions such as kyphosis or scoliosis, a full backrest that supports proper positioning is recommended. In such cases, measuring up to the nape of the neck is more appropriate than measuring below the shoulders when calculating back height. A professional assessment is advised when dealing with complex postural requirements to ensure the correct supports are in place.
It is important to note that the backrest height is just one of several measurements that need to be taken to ensure a proper fit for an electric wheelchair. Seat width, depth, and height, as well as armrest height, are also crucial factors in determining the overall comfort and functionality of the wheelchair for the user.

User posture and function
The user's posture and function should be assessed by a therapist who can then take the necessary measurements to complete the seating system. This should be done while the user is seated on a firm, flat surface, in the "ideal" posture the therapist is trying to accomplish for the user. The therapist should ensure the user is positioned correctly and is able to comfortably drive the electric wheelchair and operate its features.
Seat depth, height, and armrest height are important measurements to consider for user posture and function. The seat depth is measured from the user's posterior buttock, along the lateral thigh to the popliteal fold with your palm horizontal to the seat, usually leaving a space of about 2 inches to avoid pressure from the front edge of the seat. Seat height is determined by the height of the individual and whether the wheelchair is self-propelled. For those using their feet to propel the wheelchair, the seat height should allow them to reach the floor with their heels. Armrest height should allow the user to sit erect with level shoulders when bearing weight on their forearms.
The height of the backrest depends on the needs of the user. Users who push themselves need a backrest that allows their shoulders to move freely, while those who have difficulty sitting upright may need a higher backrest for more spinal support. Footrest length is also important, as it affects the support of the feet and thighs and the clearance of the footplates from the ground. The footplate should be about 1 to 2 inches off the ground to permit adequate ground clearance.
