Choosing the right wheelchair makes a difference in the comfort, safety, and independence of the user. In this guide, we explain, step by step, what to look for: measurements and width, type, material, how to measure the correct size, weight, and folding system.
How wide is a wheelchair?
A standard wheelchair measures between 66 and 70 cm in total width, including the wheels. Since most doors have an opening of 70–80 cm, it passes without a problem. This total width should not be confused with the size, which is the seat width (from 41 to 51 cm). If you have narrow doors or tight hallways, always measure the clear opening of the door before buying and compare it with the total width of the model.
1. Types of wheelchairs by material
The two most common options are steel and aluminum:
- Steel: more economical and very resistant. They weigh a bit more, but are perfect for home, hospital, or occasional transfers.
- Aluminum: lighter and easier to transport in the car. Ideal for people who go out often or travel.
2. Self-propelled or transit: which one do I need?
- Self-propelled (large wheel, 600 mm): the user can propel themselves thanks to the large rear wheel rims. Recommended if the person has arm strength.
- Transit / non-self-propelled (small wheel, 300 mm): more compact and lighter; requires an attendant to push it. Ideal for assisted transfers and movements.
3. How to choose the correct size (measurement table)
The size of a wheelchair is the width of the seat. To get it right, measure the hip width of the seated person and add about 2 cm for leeway. This is the equivalent:
| Size (seat width) | Hip width |
| 41 cm | 76–80 cm |
| 43 cm | 80–84 cm |
| 46 cm | 86–89 cm |
| 48 cm | 90–94 cm |
| 51 cm | 96–99 cm |
A chair that is too narrow is uncomfortable and can cause chafing; one that is too wide reduces stability and makes propulsion difficult.
4. Weight, folding, and transport
If you are going to transport the chair in the car frequently, pay attention to the weight and whether it is foldable. Foldable aluminum chairs are the most convenient to store and transport. Also check the maximum user weight (usually up to 100–136 kg).
5. Details that improve daily life
- Flip-up armrests: facilitate transfers to bed or sofa.
- Adjustable and detachable footrests: greater comfort and easy to remove.
- Puncture-proof wheels (PU): maintenance-free.
- Washable upholstery: easy hygiene.

Frequently asked questions
How wide is a standard wheelchair?
The total width of a standard wheelchair is about 66 to 70 cm including the wheels, enough to pass through most doors. The size (seat width) ranges from 41 to 51 cm and is a different measurement.
What wheelchair size do I need?
Measure the hip width of the seated person and add about 2 cm. That value indicates the size (seat width): for example, a hip of 86–89 cm corresponds to a size of 46 cm.
What is the difference between a self-propelled chair and a transit chair?
The self-propelled chair has large rear wheels with rims for the user to propel themselves. The transit chair has small wheels and needs an attendant to push it; it is lighter and more compact.
Which is the lightest wheelchair?
Foldable aluminum chairs are the lightest and easiest to transport, ideal if you are going to carry it in the car frequently.
