What fits
- Kanagawa is 84% of the size of Rhode Island.
- Rhode Island is larger by 448 km² (173 mi²), which is 19% of the area of Kanagawa.

How they differ
- Rhode Island is larger, but Kanagawa has the larger population: 9.2 million against 1.1 million, 8.40× as many people.
- Per square kilometre that is 3,865 in Kanagawa against 387 in Rhode Island: Kanagawa is 9.98× as densely populated.
- Their centres are about 10,900 km apart.
- A standard web map misstates the comparison: Rhode Island at 42°N is drawn about 1.8× too large and Kanagawa at 35°N about 1.5×, so the map shows Rhode Island as 1.41× the size of Kanagawa instead of 1.19×.
- Together Rhode Island and Kanagawa cover 5,220 km², close to the size of Trinidad and Tobago (5,120 km², 1.8% smaller).
- The gap between them, 448 km², is about the size of Antigua and Barbuda (452 km²).
- At Kanagawa's density, Rhode Island would have 10.9 million people (it has 1.1 million). At Rhode Island's density, Kanagawa would have 924,000 (it has 9.2 million).
- Rhode Island's centre is 6.3° of latitude, about 700 km, farther north than Kanagawa'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.
- Kanagawa is the 43rd largest of the 47 prefectures of Japan and covers 0.6% of its area; it is the 3rd most densely populated of them.
- Rhode Island lies about 6° of latitude (roughly 698 km) north of Kanagawa.
- Shared out evenly, each person in Rhode Island would have about 2,580 m² and each person in Kanagawa about 260 m².
- Laid side by side, Rhode Island and Kanagawa would cover 5,220 km², about the same size as Trinidad and Tobago.
- Together they have 10.3 million people, about as many people as Portugal.
- Kanagawa is drawn from 83 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.
