When a drawing or model of an object is larger or smaller than the original, and proportionally the same, the scale represents how much the object has been "grown" or "shrunk."
The scale of a map or of an enlarged or reduced model indicates the ratio between the distances on the map or model and the corresponding distances in reality or the original. For example, a map of scale 1:50,000 shows a distance of 50,000 cm (or 500 m) as 1 cm on a map, and a 1:25 scale model of a building with a height of 30 m has a model height of 1.20 m. Scale bars are a common method of indicating scale on maps.
