Understanding Scale

The scale of a model is its size as a proportion to the real-life item. For instance, a 1:18 scale model means that every 1 unit of measurement on the model equals 18 units on the real item. If you divide the real item's size by 18, you'd get the size of the 1:18 model. Please note that models can vary slightly in size, as not all real-life items, like cars or planes, have the same dimensions.
