1:12 dollhouse furniture dimensions and conversion examples
Convert real furniture dimensions into one-inch-scale workshop measurements while keeping every part in a single printable project worksheet.
How it works
At 1:12, one real foot becomes one model inch. A real 30-inch table height becomes 2.5 inches, or 63.5 mm. This direct relationship makes rough planning easy, but exact conversions are still useful for metric materials and ruler fractions.
Checked example
Example dimensions are starting points, not universal standards. A 72 × 36 × 30 inch dining table converts to 6 × 3 × 2.5 inches. A 84 × 36 inch door converts to 7 × 3 inches. Measure the real object or design reference when accuracy matters.
Workshop notes
Create one worksheet for the complete room: table, chairs, door, bookcase, sofa, and clear walking space. Exact millimetres help with cutting and 3D design, while ruler fractions show the closest practical mark on an imperial workshop ruler.
Start with the real object
Record width, depth, and height from a reliable product drawing, measured object, or your own design. Furniture called by the same name can vary widely, so treat example dimensions as planning references rather than fixed rules.
Use the one-foot-to-one-inch shortcut carefully
At 1:12, 12 real inches become 1 model inch. The shortcut is excellent for whole feet, but dimensions such as 29.5 inches still require division: 29.5 ÷ 12 = 2.4583 inches, or about 62.44 mm.
Plan a dining table example
A 72-inch-long, 36-inch-wide, 30-inch-high table becomes 6 × 3 × 2.5 model inches. In millimetres that is 152.4 × 76.2 × 63.5. Add the tabletop and each leg as separate worksheet items if their cut dimensions differ.
Plan a bookcase example
A 72 × 30 × 12 inch bookcase becomes 6 × 2.5 × 1 model inches. Remember that outside dimensions are not the same as internal shelf openings; subtract material thickness after the overall scale conversion.
Allow for material and assembly
Scale math does not automatically account for saw kerf, glue gaps, fabric thickness, hinges, or printable wall thickness. Convert the design first, then make fabrication allowances based on the material and process.
Print a room worksheet
Group all furniture and architectural openings in one project. A printed sheet reduces repeated calculations and helps you compare clearances before cutting expensive wood, card, or resin.
Frequently asked questions
Is 1:12 the same as one-inch scale?
Yes. One model inch represents twelve real inches, or one real foot.
Are the example furniture sizes standard?
No. They are realistic examples for demonstrating conversion. Measure the specific object or plan you intend to reproduce.
Should I build from inches or millimetres?
Use the unit that matches your tools and materials. The converter displays both, plus practical ruler fractions.
Why does my rounded ruler value differ from the exact result?
A ruler can show only certain fractions. The worksheet keeps the exact value and reports the rounding difference so you can decide whether it matters.
