Rhode Island is 1.32× the size of Okinawa

Rhode Island (state of the United States) covers about 2,830 km² (1,090 mi²) and Okinawa (prefecture of Japan) about 2,150 km² (829 mi²). Below, both outlines are drawn at one scale and centred on each other.

Okinawa: Part of this region's boundary is disputed with China and Taiwan. Size Versus draws Natural Earth's de facto outline, the boundary as it is held on the ground, and takes no position on it.

What fits

Okinawa is 76% of the size of Rhode Island.
Rhode Island is larger by 685 km² (264 mi²), which is 32% of the area of Okinawa.
Measured in Belgiums: Rhode Island is about 0.09, Okinawa about 0.07.

How they differ

Rhode Island is larger, but Okinawa has the larger population: 1.5 million against 1.1 million, 1.33× as many people.
Per square kilometre that is 680 in Okinawa against 387 in Rhode Island: Okinawa is 1.76× as densely populated.
Their centres are about 12,300 km apart.
A standard web map misstates the comparison: Rhode Island at 42°N is drawn about 1.8× too large and Okinawa at 26°N about 1.2×, so the map shows Rhode Island as 1.91× the size of Okinawa instead of 1.32×.
Together Rhode Island and Okinawa cover 4,980 km², close to the size of Trinidad and Tobago (5,120 km², 2.9% bigger).
The gap between them, 685 km², is about the size of Bahrain (688 km²).
At Okinawa's density, Rhode Island would have 1.9 million people (it has 1.1 million). At Rhode Island's density, Okinawa would have 832,000 (it has 1.5 million).
Rhode Island's centre is 15.8° of latitude, about 1,760 km, farther north than Okinawa'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.
Okinawa is the 45th largest of the 47 prefectures of Japan and covers 0.6% of its area; it is the 8th most densely populated of them.
Rhode Island lies about 16° of latitude (roughly 1,760 km) north of Okinawa.
Shared out evenly, each person in Rhode Island would have about 2,580 m² and each person in Okinawa about 1,470 m².
Laid side by side, Rhode Island and Okinawa would cover 4,980 km², about the same size as Trinidad and Tobago.
Together they have 2.6 million people, about as many people as Namibia.
Okinawa is drawn from 133 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.
