Will my furniture fit? How to know before you buy
The short answer: to know if a piece of furniture will fit, measure the room's clear floor area, measure the piece's footprint (width × depth), and leave room to move around it, roughly a 60–90 cm (24–36 in) walkway, and 45 cm (18 in) in front of anything with doors or drawers. Then check the route in: the narrowest doorway, hallway, or stair turn the piece has to pass. A tape measure tells you whether the numbers could work; the only way to be sure is to draw the room and the piece to scale and see it in place. That's exactly what a room planner is for, set the scale once and every piece sits at its real size.
1. Measure the space, the real, usable space
Measure the room wall-to-wall, then subtract what you can't use: the swing of each door, the space under a window where a tall piece won't sit, radiators, vents, and outlets you need to reach. That "clear" area, not the raw room size, is what your furniture actually competes for.
2. Measure the piece, width, depth, and height
Get all three dimensions of the piece (or its listing). Width × depth is its footprint on the floor; height matters for windowsills, wall cabinets, and sloped ceilings. If you're not sure a listing is right, our standard furniture sizes cheat sheet has typical real-world dimensions to sanity-check against.
3. Leave clearances, furniture needs breathing room
A piece that technically fits wall-to-wall usually still doesn't work. Rules of thumb:
| Clearance | Rule of thumb |
|---|---|
| Main walkway | 75–90 cm (30–36 in) |
| Tight walkway | ≥ 60 cm (24 in) |
| In front of drawers / doors | ≥ 90 cm (36 in) to open fully |
| Coffee table to sofa | 30–45 cm (12–18 in) |
| Chair pulled out from a table | 90 cm (36 in) from the edge |
| Either side of a bed | ≥ 60 cm (24 in) to walk / make it |
4. Check the route in
"Will it fit in the room?" and "will it fit through the door?" are different questions. A sofa that fits the living room can still be stuck at the front door, a hallway corner, or a stairwell turn. Measure the narrowest doorway width and height on the path, and remember a piece can often go through on its side or diagonally, so measure the piece's diagonal too. If it can't make a 90° turn in a tight hall, it won't matter how roomy the destination is.
5. Draw it to scale: the only way to be sure
Numbers on paper hide problems: two pieces that each "fit" can't share a wall; a bed blocks a closet door; the walkway vanishes once the rug and coffee table are in. Drawing the room and every piece to scale is the reliable check: you see the whole layout at once, at real size. That's what Fittro does: import a photo of your floor plan, set the scale once, and drop furniture in at its true dimensions. If it says it fits, it fits.
