The correct seat width for a wheelchair determines comfort, stability and safety. To ensure that the wheelchair fits perfectly, you will find a clear table and simple instructions for measuring here.

Measuring wheelchair seat width correctly

1. Sit the person on a stable chair without armrests.
2. Measure the distance between the outer hip or thigh points.
3. If you are between two sizes, choose the larger wheelchair.

This prevents pressure points and ensures that clothing, seat cushions or splints can be comfortably accommodated.

Why the right seat width is so important

A suitable seat width ensures that the body sits stable, upright and without pressure points.
A wheelchair that is too narrow can cause skin irritation or pain, while a wheelchair that is too wide reduces stability and makes it difficult to move around.
The correct seat width is crucial to ensure that posture, power transmission and seating comfort are correct.

What wheelchair sizes are available?

Wheelchairs are available in various seat widths between 30 cm and 70 cm.
Most standard models are 40-46 cm, children's and youth wheelchairs are narrower, comfort models or XXL versions are wider.
In addition to the seat width, the seat depth, seat height and backrest height also play a role in achieving an ergonomically suitable sitting position.

Conclusion

• The seat width determines comfort and stability.
• Measure the hip width at the widest point when seated.
• If you are between two sizes, choose the larger one.
