Scale

Scale

The ratio between the size of the models and the size of the prototype. This can be expressed either as a ratio or as so many millimetres per foot (or fractions of an inch per foot for American models). Usually only applicable to the rolling stock and buildings as the rest of the scenery is usually condensed to fit the available space.
