Map characteristics - Scale of the Map

Scale

The scale of a map is the ratio between distances on the map and corresponding distances in the real world, e.g., if a map has a scale of 1:50,000, then 1 cm on the map equals 50,000 cm or 0.5 km on the Earth's surface.

"Small scale" and "large scale" is often confused, e. g, 1:50,000 vs. 1:500,000

The scale controls not only how features are shown, but what features are shown, e.g., Engineering building: 0.2mm*50,000=10 m? Map projections. The Earth's surface is curved but as it must be shown on a flat sheet, some distortion is inevitable.
