Statement of Scale : In this method, we express the scale in words, or we make a statement about it; such as one centimetre to one kilometre, or one inch to one metre etc. This indicates that one centimetre on the map represents one kilometre on the ground or one inch on the map represents one mile on the ground.
Advantages :

(i) This is very simple method which is understood even by a common man.

(ii) It requires little time to express this scale.

(iii) It gives correct idea about distance.

Disadvantages :

(i) It can be understood only by those who are familiar with the unit of measurement used. For example, if we say that the scale of a map is 1 cm : 1 km, it would be understood by only that person who is familiar with the metric system of measurement.

(ii) When a map is reduced or enlarged from the original, the scale does not remain the same. This creates problems in measurement.
