The term "1:64 scale" refers to a model size where one unit of measurement on the model represents 64 of the same units in real life. For example, if a toy car is 1 inch long in 1:64 scale, the actual car it represents would be 64 inches long. This scale is commonly used in die-cast models, particularly for vehicles. Models at this scale are popular among collectors and hobbyists, especially in the Hot Wheels and Matchbox brands. They provide a compact way to display detailed replicas of real-life cars, trucks, and other vehicles, making them accessible for both play and collection.
