Planning a 15×17 Room

15×17 is the living-dining room of a 1990s American apartment, the great room of a small bungalow renovation with the kitchen wall removed, and the drawing room of a large Edwardian house. At 255 sq ft it is a big living room that gains a proper dining zone across one end.

At 1:1.13 the 204-in length carries a 120-in seating zone and an 84-in dining zone, and the 180-in width allows a 72×36-in table crosswise with 54 in of pull-out on each long side (36 + 36 + 72 = 144 of 180). Few rooms this size allow a six-seat table to run across.

What this size is best used for

1
Living-dining room with a crosswise table
Table 72×36 in across the near end with chairs on both long sides: 36 + 36 + 72 = 144 in of the 180-in width, and the 84-in zone gives 24 in behind each row of chairs once pulled out.
2
Bedroom with a home office
With the king on the 15-ft wall (52 in per side) the foot zone is 204 − 80 = 124 in: a 72-in desk against a long wall, 40 in to walk, and a 60-in dresser across the near wall.
3
Library with a reading circle
12-in bookcases on three walls, four 32-in chairs around a 40-in round table in the middle (40 + 64 = 104 in across), and 180 − 24 − 104 = 52 in of floor to each remaining wall.

Furniture sizes are the same true-to-scale pieces in the RoomSketch3D catalog; clearances are what is left after each step.

Seating (far 120 in): an 84×36-in sofa runs out of the far corner along the left 17-ft wall, a loveseat (58×35 in) on the far 15-ft wall from 36 in to 94 in, coffee table 48×24 in in the L, TV bracket on the right wall above a 12-in shelf. Path from table to shelf: 180 − 36 − 16 − 24 − 12 = 92 in.
Table 72×36 in across the room in the near 84 in, sitting 54 in from each long wall, its far edge 36 in beyond where the seating ends.
Chairs on both long sides: 36 in of pull-out each way uses 36 + 36 + 36 = 108 in of length, so with the table 36 in from the zone line the near row's pull-out is 84 − 36 − 36 = 12 in — the near row is a bench that tucks under.
A 60×16-in sideboard on the near 15-ft wall behind the bench, and the door on the right 17-ft wall at the near end, hinged toward the corner, opening into the 54-in strip beside the table.

Mistakes this size invites

Table lengthwise instead: 72 + 36 in for an end chair is 108 in in an 84-in zone.
Two 84-in sofas in the L: the second sofa on the far 15-ft wall from 36 in to 120 in leaves 60 in, and the far-right corner chair no longer fits.

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 15×17 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.
