In dollhouse miniatures, a 1:12 scale means that one inch in the miniature world represents twelve inches (one foot) in real life. This scale is commonly used for dollhouses and allows for detailed and realistic reproductions of furniture, accessories, and other items. For example, a miniature chair that measures one inch tall in a 1:12 scale would correspond to a full-sized chair that is twelve inches tall in real life. This scale is popular because it balances the level of detail with manageability, making it easier to create and collect highly detailed miniatures.
