What are the different types of scales ?

There are three types of scales used on maps: verbal, graphic, and representative fraction.

1. Verbal scale: It is a description of distance using words. For example, “1 inch equals 1 mile.”
2. Graphic scale: It is a bar line marked to show distance on the map. It is often divided into miles, kilometers, or other units of measurement.
3. Representative fraction: It is a ratio that compares the distance on the map to the actual distance on the ground. For example, “1:50,000” means that one unit on the map represents 50,000 units on the ground.
