Furniture Walkway Clearance Calculator
Place up to four pieces of furniture or reserved areas in a room and check whether a continuous walkway of the width you want runs between two doorways or to a spot — with the narrowest point and every gap measured.
Furniture Walkway Clearance Calculator calculates in your browser.
A walkway is only as wide as its narrowest point
Measuring the gap beside a sofa tells you about one spot. Whether you can actually walk through a room depends on every gap along the way — and on gaps that are offset, where the true distance runs corner to corner.
This calculator checks the whole route. Between two doorways it finds the exact narrowest point of the best route; to a spot in the room it uses a fine grid that only confirms a route it can prove, and says when a result is too close to call. Every gap to the walls and between pieces is listed as well, so tight spots off the route are visible too.
How to use the Furniture Walkway Clearance Calculator
- Choose a unit and enter the room’s length (left to right) and width (top to bottom), as on the plan.
- Keep or change the walkway width you want.
- For each piece, say whether it is furniture or an area to keep clear, then its size and its distance from the left and top walls.
- Enter the doorway you come in by: the wall, where the opening starts, and its width.
- Choose whether you are walking to another doorway or to a spot, and enter it.
How the calculation works
Gap between two pieces = √(gap across² + gap along²), measured corner to corner
Doorway to doorway: widest walker = the smallest gap a chain of pieces and walls would need to seal one door off from the other
Doorway to a spot: confirmed if every grid step keeps (walkway + cell) ÷ 2 clear; ruled out only if even (walkway − 1.41 × cell) ÷ 2 can’t get through
Doorways are reported, and the walkway is judged inside the room
Two pieces offset 3 in across and 4 in along are 5 in apart corner to corner — the narrower figure a straight tape across one axis would miss.
| Room and furniture | Walkway | Narrowest point | Result |
|---|---|---|---|
| 168 × 144 in, 84 × 36 in sofa on the top wall | 36 in | 62.29 in — between Piece 1 and the right wall | Likely fits |
| Same room, a 48 × 24 in table 28 in below the sofa | 36 in | 28 in — between Piece 1 and Piece 2 | Does not fit under the conditions checked |
| 420 × 360 cm, 220 × 95 cm sofa | 76 cm | 265 cm — between Piece 1 and the bottom wall | Likely fits |

Limitations
- The room is a rectangle and pieces are rectangles square to the walls; angled furniture, round tables, and curved sofas aren’t modelled.
- A person is modelled as a disc as wide as the walkway; carrying something wide needs more.
- Furniture-planning clearances are guides, not accessibility or building-code requirements — this doesn’t check compliance with the ADA or any local code.
- Routes to a spot use a grid of cells about 0.5 in (1.3 cm) across in a typical room; results that close to your walkway are reported as too close to call.
- Up to four pieces; anything else in the room isn’t counted.

Furniture Walkway Clearance Calculator FAQ
- How much walking space should I leave around furniture?
- About 36 in (91 cm) is often used for a main walkway and about 30 in (76 cm) as tight but usable. These are furniture-planning guides you can change. They aren’t accessibility or building-code requirements, and the calculator doesn’t check compliance with any code.
- Why isn’t one wide gap enough?
- A route is only as wide as its narrowest point. A 40 in gap next to the sofa doesn’t help if the way on to the door narrows to 28 in, so the calculator checks the whole path from the doorway, not each gap on its own.
- How is the narrowest point measured?
- Between two doorways it is exact: the widest walker that gets through is set by the smallest gap a chain of furniture and walls would need to seal one door off from the other. Gaps between offset pieces are measured corner to corner.
- What if my doorway is narrower than the walkway?
- That is normal — interior doorways are often 30–32 in. The doorway width is reported, and the walkway is judged inside the room from just inside each door, so a 32 in door doesn’t fail a 36 in walkway on its own.
- Can it suggest a better layout?
- When the route is short, it tries moving one piece at the narrowest point straight away from the other by the shortfall, re-checks the whole route, and only shows the move if the new layout really works.
- Are the measurements I enter sent anywhere?
- No. The check runs in your browser as you type. Your measurements and results are not sent to Looty Tools or stored, and the calculator area is masked from session-recording analytics. Refreshing the page clears it.
