Large Scale vs. Small Scale Maps

The scale on a map is a representative fraction, so the scale of the map on the left is a large scale map is 1:25,000 which means that objects on the map are drawn at 1/25,000 of their actual size. The map on the right a small scale map is 1:4,500,000, so objects are 1/4,500,000 of their actual size. 1/25,000 is a larger fraction than 1/4,500,000 and a larger fraction means a larger scale!
