- 2,510km²Area, publishedWikidata · agrees within 2%
The area is measured from the outline drawn above, on the WGS84 ellipsoid; the published figure is shown beside it, and a water body is kept only if the two are within 10%.
What the numbers say about Réunion
- Greenland (island), the largest of the 81 islands ranked on sizeversus, is 868× the size of Réunion; Réunion ranks 81st.
- Counted as a country, Réunion would be larger than 37 of the 212 countries listed on sizeversus and would rank 176th by area, between Luxembourg (2,610 km²) and Mauritius (2,000 km²).
- It is larger than 1 of the 51 US states and districts (the biggest of them is Washington, D.C., 162 km²) and smaller than 50.
- It is smaller than every one of the 31 provinces and regions of China.
- The closest US state is Rhode Island (2,830 km²): Réunion is 88% of the size of Rhode Island.
- Réunion lies at 21°S, close to the equator, where a standard web map (Web Mercator) is nearly true to size: it inflates area by only about 1.1×.
- Laid out flat, Réunion stretches about 56 km north to south and 63 km east to west.
- Wikidata’s published figure of 2,510 km² agrees with our measured 2,500 km², to within 2%.

Where it lies
Natural Earth’s outlines of France contain or lie within 4 km of the outline of Réunion. That is what its geometry says, and it is not a statement about who owns the water or where any border runs in it.
Where Réunion ranks
Réunion is the 81st largest of the 81 islands on sizeversus, ranked by measured area.
Sources and method
- Outline
- Natural Earth, 1:10m Geography Regions (geography_regions_polys), public domain (Geography Regions (geography_regions_polys)). Outlines of lakes are drawn at 1:10 million.
- Boundary
- A lake or a sea has no legal boundary of its own. The outline is a cartographic one, and the page says so by showing the measured area beside the published one.
- Area basis
- Measured outline: computed on the WGS84 ellipsoid from the full-detail outline and shown rounded. Published figure: Wikidata (CC0), fetched 2026-11-11. An outline is kept within 10% of the published figure and matched to other places automatically within 5%.
- Shore
- Countries whose Natural Earth outline contains or comes close to the water's outline; computed, not a statement of ownership.
- Drawing
- Each outline is projected with an equal-area projection centred on its own centroid, so areas stay true and two can be laid over each other.
