Planning a 13×20 Room
13×20 is the great room of a modest modern house, the living room of a New England Colonial with the parlour wall removed, and a common basement family room between the foundation walls. At 260 sq ft it is a large room that is still narrow enough to have one obvious axis.
At 1:1.54, 240 in long, the room divides into two 120-in halves, each deep enough for a full seating group, or into three zones of 80 in. The 156-in width means anything facing across the room still has a 62-in path, which is generous, but nothing can be arranged in a circle wider than 120 in.
What this size is best used for
- 1Great room with kitchen island
A 120-in kitchen run on a long wall at the far end with a 36×72-in island floated 42 in from the counters: 25 + 42 + 36 = 103 in of width used, 53 in left beyond the island, and a seating group in the near 120 in.
- 2Family room with a play zone
Sofa group in the far half facing the media wall, and an open 120×156-in play floor in the near half with 12-in-deep storage on the near 13-ft wall.
- 3Two-desk office with a meeting table
Two 72-in desks on facing long walls in the far half (156 − 60 = 96 in between chairs) and a 48-in round table with four chairs in the near half (48 + 72 = 120 in of the 156).
Great room with a kitchen island in a 13×20 room
Furniture sizes are the same true-to-scale pieces in the RoomSketch3D catalog; clearances are what is left after each step.
- Kitchen run 120 in wide, 25 in deep, on the far left wall from the far corner: 36-in fridge, 24 in of counter, 30-in sink base, 30-in range.
- Island 72×36 in parallel to the run, 42 in off it, its far end aligned with the fridge; 156 − 25 − 42 − 36 = 53 in beyond the island for three 24-in stools with 29 in behind them.
- The kitchen zone ends 120 in from the far wall (the run's length). Seating group in the near half: sofa (84×36 in) on the right wall facing the island side, its back 12 in off the wall, coffee table 48×20 in at 16 in, and a media unit 60×18 in on the near 13-ft wall — the sofa faces the near wall, not the island.
- Path from the entry door (near right corner) to the kitchen runs along the left side of the room: 156 − 12 − 36 − 16 − 20 = 72 in of open floor between the coffee table and the left wall.
Mistakes this size invites
- Island perpendicular to the run: a 72-in island across a 156-in width leaves 42 in each side, and one of those sides is the run's 42-in aisle, so the island blocks the route down the room.
- Seating group centred in the 240-in length: the kitchen then has 60 in of dining space at its end and the entry has 60 in, and neither is useful.

Maximum Furniture Sizes for a 13×20 ft Room
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 13×20 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.
