A scale model is a representation or copy of an object that is larger or smaller in size. Its size is proportionate to the original size of the object that it represents. The proportion is often shown in some ratio eg 1:10, which means one inch of scale model is equivalent to 10 inches of original object. Very often, the scale model is smaller than the original and is used to represent an original object, an imagination or model for an upcoming project. Scale models are built for many cars, buildings, landscapes and huge projects.
