Planning a 18×22 Room
18×22 is the two-car garage of many American houses built after 2000, sized so a full-size pickup fits in one bay; it is also the great room of larger new builds and the footprint of a typical detached studio or pool house. At 396 sq ft it is a big room by any measure.
At 1:1.22 the 264-in depth takes a 232-in pickup with 32 in to spare, and the 216-in width still holds two cars only if one is compact (80 + 70 + 36 + 30 = 216). As a living space the length allows three zones of 88 in or two of 132, each at the full 216-in width.
What this size is best used for
- 1Two-car garage with a pickup bay
An 80-in pickup 15 in from the left wall and a 70-in compact 15 in from the right wall with 36 in between: 15 + 80 + 36 + 70 + 15 = 216 in; the pickup's 232-in length leaves 32 in in front for 12-in shelves.
- 2Pool house or studio
A 96-in kitchenette on the far 18-ft wall, a 5×8 bathroom in the far right corner, a queen bed zone (60 + 30 + 30 in of clearance) in the far left, and a sofa group in the near 132 in facing the pool doors.
- 3Great room with facing sofas and a table
Sofas of 84 in on both long walls, each 24 in out, face one another across 96 in (24 + 36 + 96 + 36 + 24 = 216) with a 48-in table between; the near 108 in take a 72×36-in dining table set across the room.

Furniture sizes are the same true-to-scale pieces in the RoomSketch3D catalog; clearances are what is left after each step.
- The garage door: one 16-ft leaf in the front 18-ft wall, 12 in of wall at each end.
- Left bay: the pickup (80×232 in) parks 15 in from the left wall, nose 32 in from the back wall. Right bay: a compact (70×175 in) 15 in from the right wall, 36 in from the pickup, nose 89 in from the back wall.
- Across the back wall's right half (108 in), a 96-in workbench 24 in deep sits in the compact's 89-in nose zone with 65 in to stand at it; the left half of the back wall gets 12-in shelves within the pickup's 32-in zone with 20 in to pass.
- The side door on the right wall in the rear 89-in zone behind the compact's nose, swinging out; a 36×36-in mower spot in the front right corner beside the garage door.
Mistakes this size invites
- Two pickups: 80 + 80 + 36 + 30 = 226 in of width against 216.
- The bench across the full back wall: 24 in of bench leaves 8 in in front of the pickup's nose, so the bench stays on the compact's side.

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 18×22 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.
