A wheelchair can be narrower than a doorway and still struggle to get through it. The approach angle, door handle, threshold and space after the opening all matter. Before ordering a chair or changing a door, measure a complete route rather than comparing one headline width with another.
Measure the usable opening
Open the door to the position you can normally achieve. Measure the clear gap at its narrowest point, including the edge of the open door and anything projecting into the space. Do not rely on the nominal size of a door leaf or the outside width of its frame. Record whether a radiator, cupboard or closer stops the door opening further.
Take a photograph from both sides and label the measurements. Include the handle, any latch and the direction of opening. A photograph helps a supplier understand why a doorway that sounds wide enough on the telephone is awkward in practice. Keep private details out of images you send to retailers.
Measure the chair as used
Ask for the overall width of the exact model, seat size and wheel configuration. Include hand rims and fitted accessories rather than using folded width. Think about the space needed for your hands when propelling and for the person assisting you. A dimension that barely clears the frame may not provide a comfortable passage.
Also record length with the relevant foot supports and anti-tip components in place. A narrow chair with a long footprint may need more space to turn into a doorway than a wider but shorter configuration. Do not remove safety components to make a route work without advice from the responsible supplier or service.
Follow the route beyond the door
Draw a simple plan of the journey from the entrance to the rooms you need. Mark each turn, narrow section and stopping point. Look particularly at hallways, bathroom approaches and the space beside beds. Consider whether the chair can reverse or turn where needed, rather than assuming it will always approach straight on.
- Can the entrance door be opened and closed from the intended position?
- Is there room to wait safely while someone operates a lock?
- Does a second door create a small lobby?
- Are rugs, shoes or furniture using the clearance?
- Is the route still usable with ordinary household activity?
Test without forcing the fit
Where possible, arrange a home trial or assessment using the actual chair. A cardboard footprint can help you describe a problem but cannot reproduce caster movement, hand access, posture or the actions of an attendant. Do not force a wheelchair through a gap, lean it to one side or make structural alterations on the basis of a paper template.
If access is difficult, the answer may involve the environment, the chair configuration or both. The GOV.UK home equipment and adaptations page explains how to contact your council for an assessment. Funding and services differ by location, so establish the local process before paying for building work.
Plan for the ordinary complications
Think about entering when it is raining, bringing shopping inside, answering the door alone and reaching light switches. If an attendant helps, include their standing and turning space. A route that works only when two pieces of furniture are moved every time may be tiring to maintain. Write that inconvenience into the decision rather than treating it as a minor detail.
For example, a front door may have enough clear width but open directly onto a short hall where the chair must turn immediately. Widening only the door may leave the original problem. A measured plan gives an occupational therapist or supplier a better starting point for alternatives.
Keep access and seating decisions connected
The NHS England framework places wheelchair provision in the context of individual outcomes. In your own notes, name the rooms and activities you need to reach. Do not choose an unsuitable seat simply to achieve a narrower outside width.
Before purchasing, ask for written confirmation of dimensions, any home trial terms and the options if the quoted configuration does not fit. Keep the final route measurements with your equipment record. They will be useful when replacing the chair, planning travel or making future adaptations.
