Shanghai is 1.69× the size of Nagasaki: outlines of Shanghai and Nagasaki at the same scale
Outlines are drawn at true scale.
Sources and method
Outlines
Natural Earth, 1:10m Admin 1 - States, Provinces, public domain
Boundary
De facto, as drawn by Natural Earth. A region is drawn whole, every island included; a country is its main territory.
Area
Measured on the WGS84 ellipsoid from the full-detail outlines, shown rounded.
Drawing
Each outline is projected with an equal-area projection centred on its own centroid, so areas stay true and the two can be laid over each other.
