Can AI design my room layout?
Half. With your room measurements and furniture sizes, it suggests layouts and checks walkways and clearances. It can't see your room, so test with tape on the floor before moving heavy furniture.
01Why half-bot
- Clearance math and layout rules are easy for AI.
- Windows, doors, vents and outlets matter; give it those.
- Image tools can sketch ideas, but measurements matter more.
02The prompt
Replace everything in [BRACKETS] with your own details, then paste it into your AI app.

Based on the provided information, I've come up with two possible layouts for the room. I'll describe each layout wall by wall, check walkway clearances, and flag any potential issues. **Layout 1: Office and Lounge Separation** * North wall: The single-panel door is centered, with the sofa (7 ft L × 3 ft D) placed along the north wall, leaving about 1.5 ft of clearance on either side of the door. * East wall: The double-hung window is above the desk (5 ft L × 2.5 ft D), which is placed about 1 ft away from the window to allow for comfortable working space. The duplex outlet is 2 ft from the east corner, and the wall-mounted light switch is nearby. * South wall: The armchair (3 ft W × 3 ft D) is placed in the southwest corner, with the bookshelf (3 ft W × 1 ft D × 6 ft H) adjacent to it, running along the south wall. This creates a cozy reading nook. * West wall: The floor-level vent is centered, with the TV stand (4.5 ft L × 1.5 ft D) placed about 2 ft away from the vent to avoid blocking it. The coffee table (4 ft L × 2 ft W) is placed in front of the sofa, and the floor lamp (2 ft diameter base, 6 ft tall) is placed near the armchair. **Layout 2: Open-Concept Workspace** * North wall: The single-panel door is centered, with the desk (5 ft L × 2.5 ft D) placed along the north wall, about 1 ft away from the door. * East wall: The double-hung window is above the bookshelf (3 ft W × 1 ft D × 6 ft H), which is placed about 1 ft away from the window. The duplex outlet is 2 ft from the east corner, and the wall-mounted light switch is nearby. * South wall: The sofa (7 ft L × 3 ft D) is placed along the south wall, with the armchair (3 ft W × 3 ft D) in the southeast corner. The TV stand (4.5 ft L × 1.5 ft D) is placed near the armchair, and the coffee table (4 ft L × 2 ft W) is placed in front of the sofa. * West wall: The floor-level vent is centered, with the floor lamp (2 ft diameter base, 6 ft tall) placed about 2 ft away from the vent to avoid blocking it. **Clearance Check:** * Layout 1: The clearance between the sofa and the desk is about 4 ft, which is sufficient for walking. However, the space between the armchair and the bookshelf is about 2 ft, which might be a bit tight. * Layout 2: The clearance between the desk and the sofa is about 4 ft, which is sufficient for walking. The space between the armchair and the TV stand is about 2.5 ft, which is relatively comfortable. **Recommendation:** Try Layout 1 first, as it separates the office and lounge areas, creating a clear distinction between work and relaxation spaces. However, be mindful of the tight clearance between the armchair and the bookshelf. If you find it too cramped, consider swapping the armchair and the bookshelf or adjusting their positions to create more breathing room.
Verify that the answer respects the no‑blocking rule and includes clearance details.

[DIMENSIONS]About 13 feet by 16 feet, roughly rectangular but the northwest corner has a 3‑foot by 4‑foot cut‑out that makes a small nook.[LOCATIONS]Front door on the north wall, about 2 ft from the west corner; a double‑pane window on the east wall centered; two standard outlets by the desk area; a ceiling vent near the middle of the room; a small vent on the south wall near the floor.[ITEM: SIZE]Sofa – 7 ft long, 3 ft deep; Desk – 5 ft wide, 2.5 ft deep; Bookshelf – 3 ft tall, 2 ft wide; Coffee table – 4 ft long, 2 ft wide; Armchair – 3 ft wide, 3 ft deep; Floor lamp – 5 ft tall.[USES]I need a home office space for a laptop and printer, a yoga area for daily practice, room for occasional guests to sleep on a futon, and a spot for my kids' art projects and craft supplies.

What came back (excerpt):
In both layouts, I've tried to maintain a minimum of 2-3 ft of clearance between furniture pieces to ensure comfortable movement. However, in Layout 1, the space between the sofa and the coffee table might be a bit tight (about 1 ft).
Read the full answer
Based on your requirements, I've come up with two possible layouts for your 13x16 feet room. Here they are: **Layout 1:** * North wall: Front door (2 ft from the west corner), sofa (7 ft long, 3 ft deep) placed along the north wall, leaving about 2 ft of space between the door and the sofa. * East wall: Double-pane window centered, bookshelf (3 ft tall, 2 ft wide) placed near the window, about 1 ft away from the wall. * South wall: Desk (5 ft wide, 2.5 ft deep) placed along the south wall, with the small vent near the floor. The armchair (3 ft wide, 3 ft deep) is placed in the corner, near the desk. * West wall: Coffee table (4 ft long, 2 ft wide) is placed in front of the sofa, leaving about 1 ft of space between the sofa and the coffee table. The floor lamp (5 ft tall) is placed near the coffee table. **Layout 2:** * North wall: Front door (2 ft from the west corner), armchair (3 ft wide, 3 ft deep) placed near the door, about 1 ft away from the wall. * East wall: Double-pane window centered, desk (5 ft wide, 2.5 ft deep) placed near the window, about 1 ft away from the wall. The bookshelf (3 ft tall, 2 ft wide) is placed near the desk. * South wall: Sofa (7 ft long, 3 ft deep) is placed along the south wall, with the small vent near the floor. The coffee table (4 ft long, 2 ft wide) is placed in front of the sofa, leaving about 1 ft of space between the sofa and the coffee table. * West wall: The floor lamp (5 ft tall) is placed near the northwest corner, and the yoga area is defined by a mat or a rug, placed in the 3x4 ft nook. **Clearance Check:** In both layouts, I've tried to maintain a minimum of 2-3 ft of clearance between furniture pieces to ensure comfortable movement. However, in Layout 1, the space between the sofa and the coffee table might be a bit tight (about 1 ft). Similarly, in Layout 2, the space between the desk and the bookshelf might be a bit tight (about 1 ft). These areas might require some adjustments or compromises to ensure comfortable movement. **What to try first:** I would recommend trying Layout 1 first, as it seems to provide a more defined separation between the different areas of the room (office, yoga, guest sleeping area, and art projects). The sofa along the north wall creates a clear boundary for the guest sleeping area, and the desk near the south wall provides a dedicated space for office work. However, feel free to experiment with both layouts and adjust them according to your personal preferences and needs.
Verify that the suggested clearances fit the actual room size.
How each run works: we fill the prompt with a made-up sample, run it once in Llama 3.3 70B, and GPT-OSS 120B grades the answer against the prompt's own rules. Word limits are counted by code, and every quote flagged as made up is checked against the full answer. Your results can differ. How we test.
