Power Wheelchair Measurement Guide
| |
| Seat Width |
| Measure at the widest point of the body from knee to hip, then add approximately an inch to add some “wiggle room.” Keep in mind that bulkier clothing (such as a winter coat) will require additional width to maintain equivalent space. |
| |
| Seat Depth |
| Measure from the backside to the inside of the knee, then subtract approximately two inches. You may add several inches if you prefer more leg overhang to allow for easier leg lifting. |
| |
| Back Height |
| Measure from the bottom of the seat to the top. Upper back support is critical for power wheelchair users, particularly at initial acceleration. |
| |
| Hanger Angle |
| Measure horizontally. A tighter angle facilitates tighter steering. The preferred angle will depend on the knee’s ability to bend. The resulting angle will also determine how far the toes extend from the body. |
| |
| Front Seat to Floor |
| Measure from the underside of the knee to the sole of the foot. Subtract the thickness of the compressed cushion, and add approximately two inches for footrest clearance. (Since power wheelchairs are rarely foot-propelled, you need not consider excluding the additional two inches for the footrest clearance, as you sometimes might with a manual wheelchair.) |
