1:12 scale is a traditional scale (ratio) for models and miniatures, in which 12 units (such as inches or centimeters) on the original is represented by one unit on the model. Depending on application, the scale is also called one-inch scale (since 1 inch equals 1 foot), or six-inch scale (since 6 inches equals 6 feet).
The scale is popular for dollhouses, especially those aimed at adult collectors. It is also used for model live steam railroads, and rather rarely, for high-end die-cast model and radio-controlled cars.
1:12 scale is also popular for action figures and related toys, especially those based on super-heroes and related concepts (such as Marvel Legends and DC Universe Classics). It has also been used for at least one related game (Shadowrun Duels).
The 1:12 scale was also used in Jonathan Swift's book Gulliver's Travels. The ratio was used to compare Gulliver to the Lilliputians.
