==========================================================================
1:2,000,000 to about 1:250,000 are SMALL scale maps. Items on these maps appear small (e.g. a county on a 1:2,000,000 map is much smaller than on a 1:100,000 map).
1:24,000 on towards 1:9,600 are LARGE scale maps. Items on these maps appear larger.
1:100,000 is pretty much in the middle - intermediate scale.
