If you're new to models, the scales they are built to may at first seem a bit confusing, but in reality it is quite straightforward. Scales are expressed as a fraction, such as 1/43 although more commonly as a ratio, such as 1:43 where '1' represents the size of the original subject and '43' represents how many times smaller the model is in relation to that subject. For example, a car measuring 4 metres in length when divided by 43, would result in a model being 9.3cm in length.

All our descriptions of models include an indication to that particular models size. However, for quick reference, approximate sizes of the most common model types are shown below, but remember, they will vary from model to model depending on the size of the original subject.
