What fits
- Osaka is 65% of the size of Rhode Island.
- Rhode Island is larger by 977 km² (377 mi²), which is 53% of the area of Osaka.
- Measured in Belgiums: Rhode Island is about 0.09, Osaka about 0.06.
How they differ
- Rhode Island is larger, but Osaka has the larger population: 8.8 million against 1.1 million, 8.04× as many people.
- Per square kilometre that is 4,758 in Osaka against 387 in Rhode Island: Osaka is 12.3× as densely populated.
- Their centres are about 11,100 km apart.
- A standard web map misstates the comparison: Rhode Island at 42°N is drawn about 1.8× too large and Osaka at 35°N about 1.5×, so the map shows Rhode Island as 1.85× the size of Osaka instead of 1.53×.
- Together Rhode Island and Osaka cover 4,690 km², close to the size of Trinidad and Tobago (5,120 km², 9.3% bigger).
- The gap between them, 977 km², is about the size of Åland (942 km²).
- At Osaka's density, Rhode Island would have 13.5 million people (it has 1.1 million). At Rhode Island's density, Osaka would have 719,000 (it has 8.8 million).
- Rhode Island's centre is 7.1° of latitude, about 790 km, farther north than Osaka's.
- Rhode Island is the 50th largest of the 51 states and districts of the United States and covers less than 0.1% of its area; it is the 3rd most densely populated of them.
- Osaka is the 46th largest of the 47 prefectures of Japan and covers 0.5% of its area; it is the 2nd most densely populated of them.
- Rhode Island lies about 7° of latitude (roughly 788 km) north of Osaka.
- Shared out evenly, each person in Rhode Island would have about 2,580 m² and each person in Osaka about 210 m².
- Laid side by side, Rhode Island and Osaka would cover 4,690 km², 91% of the size of Trinidad and Tobago.
- Together they have 9.9 million people, about as many people as the United Arab Emirates.
- Osaka is drawn from 55 points: at a size under 2,500 km² the outline is a sketch, so the overlap shows the proportions rather than the exact shape.

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.
