Planning a 16×20 Room
16×20 is the great room of larger 2000s American houses, the size of a single-car garage plus a workshop bay, and the floor of a two-bedroom cottage's entire living area. At 320 sq ft it is a big room by any standard and the smallest where two full seating groups and a dining table coexist.
At 1:1.25, 240 in long and 192 in wide. Three 80-in zones in a line, or two 120-in halves each wide enough for facing sofas. The 192-in width also holds an island with 48-in aisles on both sides (25 + 48 + 36 + 48 = 157) and 35 in spare, so the kitchen-living plan has generous circulation.
What this size is best used for
- 1Kitchen-dining-living great room
Kitchen run 120 in along one long wall at the far end, a 72×36-in table beside it with a 42-in aisle, and a full seating group in the near 120 in.
- 2Two seating groups
Facing sofas and a fireplace in the far 120 in (as in a 16×12), and a loveseat with two chairs around a 40-in round table in the near 120 in, divided by a 72×14-in console.
- 3Garage for one car plus workshop
A 190-in car on the left side (72 in wide plus 36 in of door swing = 108 of the 192-in width), a 96×30-in bench and an 84×24-in tool wall on the right side's 20-ft wall, and 240 − 190 = 50 in at the car's end for 24-in shelving.

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 long and 25 in deep along the far end of the left 20-ft wall: fridge 36, counter 24, sink base 30, range 30, with upper cabinets above and no island.
- Dining table 72×36 in parallel to the run, 42 in from the counter's edge, its far end 24 in from the far wall: chairs on the kitchen side pull out into the 42-in aisle, chairs on the other side pull out 36 in, and 192 − 25 − 42 − 36 − 36 = 53 in of walkway remain along the right wall.
- Living zone in the near 120 in at full width: an 84×36-in sofa against the middle of the near 16-ft wall, 54 in to each corner, a 48×20-in coffee table 16 in in front, and a 32-in chair on each long wall facing the other across 192 − 64 = 128 in, and the TV on a bracket on the left 20-ft wall between the kitchen run's end and the near corner. Between the coffee table's far edge and the dining chairs there are 240 − 120 − 36 − 16 − 20 = 48 in of open floor.
- Entry door at the near corner of the right 20-ft wall, hung at the corner, giving onto the 54-in gap beside the sofa's arm.
Mistakes this size invites
- An island parallel to the run: 25 + 42 + 36 = 103 in of the 192-in width, and the table then has 89 in, which is 36 of table plus one row of 36-in pull-outs and a 17-in strip nobody can walk.
- Kitchen across the far 16-ft wall with the table crosswise behind it: 96 in of kitchen, 108 in of dining with two rows of chairs, and 84 in of living add up to 288 in, 48 more than the room has.

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 16×20 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.
