Planning a 15×15 Room
15×15 is the square great room of small ranch houses, the primary bedroom of luxury condos, and the formal living room of larger Colonials. At 225 sq ft it is the size at which a room can hold two facing sofas and still have a walkway behind both.
Four 180-in walls. Two 84-in sofas facing each other 30 in off opposite walls leave 180 − 60 − 72 = 48 in between them for a coffee table, and 48 in per side of each sofa on its wall. The square makes a fireplace and a TV on adjacent walls workable with the sofas facing each other across both.
What this size is best used for
- 1Living room with two facing sofas
Sofas 30 in off opposite walls, a 48×24-in coffee table between them with 12 in to each sofa — tight, so 24 in off the walls gives 60 in between and 18 in each side of the table.
- 2Primary bedroom with a seating group
King on one wall (52 in per side); beyond its foot lie 180 − 80 = 100 in, where a 58-in loveseat faces the bed with a 42-in walkway and no dresser on that wall.
- 3Dining room for twelve
A 120×48-in table centred leaves 30 in per end and 66 in per side; sideboards 18 in deep on both long walls leave 48 in of pull-out.

Furniture sizes are the same true-to-scale pieces in the RoomSketch3D catalog; clearances are what is left after each step.
- Sofa A (84×36 in) 24 in off the left wall, centred; sofa B the same 24 in off the right wall. Between their front edges: 180 − 24 − 36 − 36 − 24 = 60 in.
- Coffee table 48×24 in centred between them, 18 in from each sofa.
- Fireplace centred on the far wall: both sofas face each other across the hearth's line, and the 48 in beyond each sofa's far arm (180 − 84 = 96, split 48 per side) keeps the hearth's 36-in clearance.
- TV on the near wall above a 60-in console 18 in deep, centred; the sofas' near arms are 48 in from that wall, so 30 in of path separate them from the console's front. Door in the near right corner, hinged at the corner: its 32-in arc stops 16 in short of the sofa's arm (48 − 32 = 16).
Mistakes this size invites
- Both sofas against the walls: the 108 in between them becomes a coffee table with a moat, and nobody can hear across it.
- A king bed with the loveseat at its foot and a dresser on the same wall: 58 + 60 = 118 in of a 180-in wall fits, but the walkway between loveseat and footboard drops to 42 − 20 = 22 in where the dresser is.

Lists like this can't tell you if it actually works
"A 3-seater sofa fits" is true — until the door swing eats two feet of wall, the radiator blocks the long wall, or the walkway to the window shrinks to 20 inches. The only way to know your layout works is to see it: draw the 15×15 ft room, place real furniture at true scale, and check the flow.
That's exactly what RoomSketch3D does. Drag-and-drop true-to-scale furniture pieces into your exact room and walk through it in 3D — before you buy, move, or assemble anything.
