Furniture Scale Visualizer

Drop a 1.70 m human silhouette onto a room plan alongside up to six preset furniture pieces, drawn at true scale. Get a verdict on whether the 60 cm circulation paths survive. Your eye will lie to you; this one won’t.

What problem this solves

Most furniture regret happens on delivery day: the sofa is 25 cm longer than the showroom sample, the dining table crowds the sideboard, the king bed blocks the wardrobe door. Online room planners help, but they default to one-pixel-per-cm scaling and a fixed camera angle that hides the real-life feeling of being inside the room. This tool does the opposite: it draws the room and the furniture to the same scale, then puts a human silhouette next to them so the eye calibrates instantly.

The presets are drawn from typical residential spec sheets: a 3-seat sofa is 220 cm wide × 95 cm deep; a queen bed is 160 × 200 cm; a 6-seat dining table is 200 × 90 cm. These are not aspirational measurements — if your delivery dimensions differ by more than 5%, edit the width/depth fields and re-render.

Who it’s for

Why real-scale beats summary numbers

Designers talk about room scale as if it were an abstract ratio, but humans handle scale visually. A floor plan with measurements is “logical”; an actual-scale render is “felt.” When you can see the human silhouette next to a king bed, you realise a king is the same width as an adult with arms outstretched — useful for figuring out side-table reach, less useful for fitting two king beds in a guest room. The visualization is the point.

Limitations

Practical sizing rules

Living room: a 3-seat sofa needs at least 240 cm wall to sit against (sofa 220 + 10 cm each end). Around a coffee table, allow 45 cm to the sofa. Behind the sofa, allow 90 cm for one person to pass. Bedroom: between a queen bed and the opposite wall, allow 60 cm minimum so you can make the bed. Around a king bed, allow 70 cm on three sides. Dining room: between table edge and wall, allow 90 cm so a chair can be pulled out and someone can pass behind the seated person.

Common questions

What if my sofa or bed doesn’t match the preset?

Use the custom width/depth fields. Sectional sofas in particular vary hugely: a 3-piece sectional can run 280 cm wide on the long side while a 2-piece is closer to 200 cm. Treat the preset as a starting point and edit once you have the actual delivery dimensions.

Why is the human silhouette only 1.70 m? My household is taller.

1.70 m is the average adult height worldwide and the median height in most residential briefs. If you’re designing for a tall client (above 1.85 m), mentally scale the silhouette up by 10% — that affects reach clearances more than circulation paths.

Can I check whether a dining table fits with chairs pulled out?

Not directly with this tool — add 50 cm on each side of the table mentally (50 cm = dining chair pulled out + body sitting). The preset table footprints do not include chair overhang. If you need precise chair clearance, model the chairs as separate pieces with the same preset list.

Does this replace a 3D render?

No. This is a fast top-down scale check — use it for layout decisions before you commit to finishes. For client presentations, switch to a real 3D renderer (SketchUp, Planner 5D, Chief Architect) once the layout is finalised.
