Mongolia and the US on a world map
Mongolia reaches from 42°N to 52°N; the US from 19°N to 71°N, with Hawaii in the south and Alaska in the far north. Most world maps use the Mercator projection, which enlarges places more the further they are from the Equator. It draws Mongolia about 2.14 times its real size and the US about 2.3 times (Alaska far more than Florida). So the two look roughly the right size against each other on a normal world map; the map above shows them exactly.
