Room Layout & Furniture Fit Calculator
Check the free floor a layout leaves and whether a big piece will actually make it through the door.
Fit the room, not just the wall
In a small space, floor is the scarcest resource. A layout can look balanced on paper and still feel tight because the pieces, added up, leave too little room to move. Subtracting each footprint from the room area turns that feeling into a number you can plan against before anything gets carried up the stairs.
And a great layout is useless if the furniture can’t get in the door. The fit check answers that first question. Once the big pieces are placed, plan the storage around them with the Storage Volume & Capacity Calculator.
Frequently Asked Questions
How much free floor should a room keep?
As a rule of thumb, a room feels open and moves well when roughly 30 to 50 percent of the floor stays clear. Below about 30 percent it starts to feel cramped and paths get awkward; above 50 percent it can feel sparse. The calculator reports the exact free area and the walkable percentage so you can judge against that range.
Why do you enter the room in feet but furniture in inches?
Rooms are usually described in feet, while furniture is sold and measured in inches — so the tool takes each in its natural unit and converts a footprint (width × depth in inches) to square feet before subtracting it. That avoids the error of accidentally mixing the two, which is easy to do by hand.
How do you know if a couch will fit through a door?
A rigid item passes through an opening if its two smaller dimensions each clear the opening's width and height — you tilt the piece so its longest dimension goes through the depth of the doorway. The tool sorts the item's three sides and the opening's two, checks the smaller pair, and reports the tightest clearance so you can see how much room to spare (or how far short) you are.
It says it fits, but only just — should I trust it?
Treat a clearance of an inch or two as tight rather than safe. Real doorways have trim, handles, and hinges that shave off usable width, and upholstered furniture doesn't compress the way its listed size suggests. When it's close, measure the actual narrowest point, and remember you can often remove a door or the furniture's feet to gain an inch.
Educational tool. Footprints are treated as simple rectangles; the fit check assumes a rigid item and ignores trim, handles, and turning room in the hallway.
