How Wide Should Doors and Hallways Be to Age in Place?
TL;DR: Plan 36-inch doors (about 32 inches clear), hallways 42 inches or wider, a 5-foot turning circle in the bath, kitchen and bedroom, and a zero-step entry. In a new home these are just numbers on the plan. In an older house they mean tearing out walls.
Most people never think about how wide a door is until the day they can't get through it.
It happens after a hip surgery, when the walker won't fit through the bathroom door. Or when a parent moves in and the wheelchair scrapes both sides of the hallway. In an existing house, widening doors means tearing out framing, trim and drywall. In a new home, it costs almost nothing, because it's just a number on the plan.
Here are the numbers that matter.
The measurements
| Where | Typical older home | Plan for aging in place | Why |
|---|
| Interior doors | 28"–30" | 36" door (about 32" clear opening) | A standard wheelchair is about 25"–27" wide; a walker plus hands needs room too |
|---|
| Hallways | 36" | 42" or wider | Room to walk beside someone, or roll and turn into a doorway |
|---|
| Turning space | Rarely planned | 5-foot circle in the bath, kitchen and bedroom | Lets a wheelchair turn around without backing out |
|---|
| Front and garage entry | Step up, 32"–36" door | Zero-step, 36" door | No lip, no ramp to add later |
|---|
About "clear opening": a 36-inch door doesn't give you 36 inches to pass through. The door's thickness and the stops take a few inches, leaving about 32 inches of clear width, the width accessibility guidelines aim for.
Where people forget
- The bathroom door. It's usually the narrowest door in the house and the one you'll need most.
- The closet doors. A walk-in closet you can't walk into isn't much use.
- The laundry room. You'll want room for a basket, or a cart.
- Pocket and barn doors. They can be good choices because nothing swings into the room, as long as the opening is wide enough.
Why this is easy in a single-level SIP home
Our homes are one level on a slab, so there are no stairs to work around and no step at the door. Open great-room layouts also mean fewer doors and hallways to begin with. Hallways are just the paths between rooms, and we size them for a walker from the start.
On a DreamStart design, wide doors and halls are part of the plan, not an upgrade. Read the full checklist on our aging-in-place homes page.
Walk it before it's built
Numbers on a drawing are hard to picture. That's why every DreamStart design package includes a Walk Your Plans visit: your full-size floor plan laid out so you can walk the halls, try the turns and stand in the shower space before anything is ordered. Bring a walker if you want to test it. You make final changes right there.
