A scale model is a physical model that is geometrically similar to an object. Scale models are generally smaller than large prototypes such as vehicles, buildings, or people; but may be larger than small prototypes such as anatomical structures or subatomic particles. Models built to the same scale as the prototype are called mockups.

A simple H0 (1:87) scale model railroad, consisting of three interconnected modules, each 70 x 100 cm in size. It has two concentric ovals of track and a few switches to sidetracks. It makes no pretension of being a copy of "real life". Using low-cost landscaping parts, house kits and rolling stock, it was built for a total of only a few hundred dollars.
