Australian Capital Territory is 1.09× the size of Okinawa
Australian Capital Territory (territory of Australia) covers about 2,350 km² (907 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 91% of the size of Australian Capital Territory.
- Australian Capital Territory is larger by 201 km² (77.7 mi²), which is 9.4% of the area of Okinawa.
- Measured in Belgiums: Australian Capital Territory is about 0.08, Okinawa about 0.07.
How they differ
- Australian Capital Territory is larger, but Okinawa has the larger population: 1.5 million against 482,000, 3.03× as many people.
- Per square kilometre that is 680 in Okinawa against 205 in Australian Capital Territory: Okinawa is 3.32× as densely populated.
- Their centres are about 7,210 km apart.
- A standard web map misstates the comparison: Australian Capital Territory at 35°S is drawn about 1.5× too large and Okinawa at 26°N about 1.2×, so the map shows Australian Capital Territory as 1.34× the size of Okinawa instead of 1.09×.
- Together Australian Capital Territory and Okinawa cover 4,500 km², close to the size of Trinidad and Tobago (5,120 km², 14% bigger).
- The gap between them, 201 km², is about the size of Aruba (170 km²).
- At Okinawa's density, Australian Capital Territory would have 1.6 million people (it has 482,000). At Australian Capital Territory's density, Okinawa would have 440,000 (it has 1.5 million).
- Okinawa's centre is 61.3° of latitude, about 6,820 km, farther north than Australian Capital Territory's.
- Australian Capital Territory is the 8th largest of the 8 states and territories of Australia and covers less than 0.1% of its area; it is the 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.
- Okinawa lies about 61° of latitude (roughly 6,820 km) north of Australian Capital Territory, on the other side of the equator.
- Shared out evenly, each person in Australian Capital Territory would have about 4,880 m² and each person in Okinawa about 1,470 m².
- Laid side by side, Australian Capital Territory and Okinawa would cover 4,500 km², 88% of the size of Trinidad and Tobago.
- Together they have 1.9 million people, 97% as many people as Lesotho.
- Australian Capital Territory is drawn from 52 points and Okinawa is drawn from 133 points: at sizes under 2,500 km² the outlines are a sketch, so the overlap shows the proportions rather than the exact shape.

- Wikidata's official figure of 2,360 km² agrees with our measured area of 2,350 km², to within 2%.
- Our measured 2,150 km² is 5.8% below Wikidata's official figure of 2,280 km². Official figures can include inland water or count land that an outline draws differently. This difference is flagged for review.

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.
