Why Narrow Doorways Become a Problem at Home

A narrow doorway may not seem like a problem until moving through it starts becoming awkward. You may find yourself turning sideways, catching a walker on the frame, or having difficulty getting a wheelchair through comfortably.

Before deciding that a doorway needs to be widened, start by noticing what is actually making it difficult to use. Is the opening itself too narrow? Does the door take up too much space when it’s open? Is there a tight turn just before the doorway? Or is furniture making the approach harder than it needs to be?

Once you understand the problem, you can look for the simplest solution that makes the doorway easier to use.

Start With an Occupational Therapist Home Safety Assessment

An occupational therapist home safety assessment is the most reliable first step before any structural change. The therapist evaluates how you move through your home, measures the spaces you use daily, and recommends practical solutions tailored to your routines and abilities.

The therapist looks at the whole picture, not just the doorway: the approach path, turning space on either side, floor surface, and how you transfer between rooms.

Occupational therapy services may be available through community health programs, private clinics or other health services in your area. Availability, referral requirements and possible funding vary, so check what is offered where you live.

How to Measure Your Doorway Clearance

Measuring the clear opening of a doorway gives you the exact numbers needed to choose the right solution. The clear opening is the widest space you can pass through when the door is fully open, measured from the face of the open door to the opposite door stop.

What You Will Need

• A metal tape measure (a fabric one can stretch and give you a false reading)
• A pencil and paper, or your phone for notes
• A second person to help hold the tape steady if the doorway is wide

Step-by-Step Measurement Guide

1. Open the door completely so it rests against the wall or door stop.
2. Locate the door stop, the thin trim inside the frame the door closes against. Measure from the face of the open door to this stop, not the outer frame edges.
3. Measure the clear opening and write down the measurement.
4. Look at the approach on both sides. Notice whether a narrow hallway, sharp turn, furniture or another obstacle makes it harder to move through the doorway.
5. If someone uses a walker, wheelchair or other mobility aid, consider how comfortably that particular person and device can actually move through the space.

Interpreting Your Measurements

Once you know the clear opening, don’t look at the number by itself. What matters is whether the person who uses the doorway can move through it comfortably.

A doorway may appear wide enough but still be difficult to use because of a sharp turn, limited space on one side, nearby furniture or the way the door swings.

If someone uses a walker, wheelchair or other mobility aid, consider the actual person, device and route through the doorway. If a structural change may be needed, check the requirements that apply where you live and consider getting professional advice.

Common Measuring Mistakes

• Measuring the rough opening instead of the clear opening. The rough opening is the hole in the wall before the frame is installed. It is always wider, sometimes by 5 to 8 centimeters, and gives a misleading sense of space.
• Forgetting about the swing. A door that opens into a tight hallway may hit a wall or fixture before it reaches full openness. Measure the actual clearance with the door fully open, not just the frame itself.
• Ignoring the approach path. A doorway may measure adequately, but if there is a sharp turn or a narrow hallway leading to it, the effective clearance is reduced. Measure the width of the hallway and the turning space on both sides of the door.

When to Call a Professional Measurer

If the doorway is visibly uneven, difficult to measure, or you’re considering a structural change, it may be worth having a qualified professional assess it.

If you’re applying for a home adaptation or accessibility funding program, check the program’s requirements before beginning work. Some programs may require particular assessments, estimates or documentation.

If You Use a Wheelchair or Walker

Wheelchairs, walkers and other mobility devices vary in size, and people use them differently. The space needed to move comfortably through a doorway can also depend on the approach to the door and the amount of room available on either side.

Rather than relying on one measurement alone, check the actual clear opening and how comfortably the person and mobility device can move through it.

Accessibility Standards Canada provides guidance on accessible housing and paths of travel that can be useful when planning renovations. However, the requirements that apply may vary depending on the type of building and where you live. For structural changes, check applicable local requirements or ask a qualified professional.

Could the Door Itself Be Part of the Problem?

Sometimes the door itself reduces the usable opening. Before assuming that the entire doorway needs to be widened, consider whether changing the door, its swing or another part of the doorway could make it easier to use.

You may come across offset or swing-clear hinges suggested as ways to increase the usable opening of some doorways. However, they are not the right solution for every doorway. The type and weight of the door, the surrounding space and the way the doorway is used all matter.

If you’re considering changing the hinges, door or direction in which the door opens, get advice for your particular doorway rather than assuming one solution will work everywhere.

When the Doorway Really Does Need to Be Widened

Sometimes the doorway itself simply isn’t wide enough for the person who needs to use it. In that case, widening the opening may be the right solution.

This can be more involved than it appears. The wall may contain electrical wiring, plumbing or structural framing, and changing the opening may affect trim, switches and the surrounding wall.

For that reason, widening a doorway is generally something to discuss with a qualified contractor rather than treating it as a simple DIY project. A professional can also help determine whether permits or other local requirements apply.

If you’re already renovating or building a home, thinking about doorway access early may make future changes easier and less disruptive.

Start With the Simplest Change

A narrow doorway doesn’t always require construction. First look at what is actually making it difficult to use.

Sometimes moving furniture, clearing the approach or changing the way the space is arranged may be enough. If gripping or turning the doorknob is the problem, a lever-style handle or an easier-to-grip knob may help.

In other cases, changing the door or its hardware may improve access. And sometimes widening the doorway really is necessary.

Start with the problem, then choose the solution—not the other way around.

Planning for Safety and Long-Term Comfort

A thoughtful approach considers both the present need and how needs may change. A solution that works today with a walker may need revisiting if a wheelchair becomes necessary later.

Think about the whole route, not just the door. A wider doorway may not solve the problem if there’s a sharp turn, crowded hallway, difficult threshold or something else making the approach hard to use.

Keep doors and hardware working smoothly, and pay attention if a door begins sticking, sagging or becoming harder to open. Small problems are usually easier to deal with before they become bigger ones.

A Doorway Should Make Life Easier, Not Harder

You may walk through the same doorway dozens of times a day without thinking about it. But if you begin turning sideways, catching a walker on the frame, struggling with the door or avoiding a room because getting through has become difficult, it’s worth paying attention.

That doesn’t automatically mean you need a major renovation.

Start by noticing what is making the doorway difficult to use. A small change may be enough. If it isn’t, you can then consider whether changing the door, widening the opening or getting professional advice makes sense.

The goal isn’t to make every doorway in your home meet some imaginary ideal. It’s to make it easier for you to move through your home safely, comfortably and independently.
