1:43 scale is a model scale that represents a ratio of 1 unit on the model to 43 units in real life. This means that if an object is 43 inches in real life, it would be approximately 1 inch long in a 1:43 scale model. This scale is commonly used for model cars, trucks, and other vehicles, and it allows for a compact representation of these larger objects while still maintaining a level of detail.
