How Dollhouse Scale Works
Dollhouse scale tells you how many real-life units fit into one miniature unit. In 1:12 scale — the most popular dollhouse scale, also called one-inch scale — one inch on the miniature equals twelve inches (one foot) in real life. So a real 6-foot sofa becomes a 6-inch miniature sofa. The formula is simple: miniature size = real size ÷ scale number.
Common Dollhouse Scales
- 1:12 (one-inch scale) — the standard for collector dollhouses; the widest selection of furniture and accessories.
- 1:16 (3/4 scale) — used by vintage Lundby and petite dollhouses.
- 1:24 (half scale) — half the size of 1:12; great for shelf-top displays and smaller rooms.
- 1:48 (quarter scale) — tiny and intricate; popular for micro room boxes.
- 1:144 (micro scale) — a dollhouse inside a dollhouse; for the truly patient.
Diorama and Model Scales
Model and diorama builders work in their own set of scales. 1:64 scale — also called S scale — is the home of Hot Wheels and Matchbox diecast cars and the dioramas built around them: garages, streets, and race scenes. 1:43 scale is the classic diecast collector car scale, common in O-gauge railroading and display dioramas. The converter above handles both worlds, so whether you are furnishing a dollhouse or laying out a 1:64 street scene, one tool does the math.
Frequently Asked Questions
How do I convert real measurements to 1:12 scale?
Divide the real measurement by 12. A real 72-inch (6-foot) door becomes a 6-inch miniature door (72 ÷ 12 = 6).
What is 1:64 scale in inches?
In 1:64 scale, one inch on the model equals 64 inches (5 feet 4 inches) in real life. A real 10-foot wall becomes just under 2 inches long (120 ÷ 64 = 1.875).
What scale is a Hot Wheels car?
Hot Wheels and Matchbox cars are 1:64 scale (S scale), the standard scale for diecast diorama scenes.
How do I convert between two miniature scales?
Convert to real size first, then to the new scale. For example, a 3-inch item in 1:12 equals 36 inches real (3 × 12), which is 1.5 inches in 1:24 (36 ÷ 24).
