The numbers

- 7,910km²Area, publishedWikidata · 5.2% above our measure, flagged
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%. This one is between 5% and 10% apart, so it is flagged and no comparison is built for it automatically.
What the numbers say about Roosevelt Island
- Greenland (island), the largest of the 81 islands ranked on sizeversus, is 290× the size of Roosevelt Island; Roosevelt Island ranks 74th.
- Roosevelt Island sits between Anticosti Island (7,700 km²) and Wrangel Island (7,100 km²) in the ranking.
- Counted as a country, Roosevelt Island would be larger than 45 of the 212 countries listed on sizeversus and would rank 168th by area, between Lebanon (10,000 km²) and Palestine (6,070 km²).
- It is larger than 3 of the 51 US states and districts (the biggest of them is Delaware, 5,170 km²) and smaller than 48.
- It is larger than 1 of the 31 provinces and regions of China (the biggest of them is Shanghai, 6,750 km²) and smaller than 30.
- The closest Chinese province is Shanghai (6,750 km²): Roosevelt Island is 1.11× the size of Shanghai.
- On a standard web map (Web Mercator), a place at 79°S is drawn about 29.1× too large in area, so Roosevelt Island looks bigger there than it is.
- Laid out flat, Roosevelt Island stretches about 125 km north to south and 106 km east to west.
- Our measured 7,500 km² is 5.2% below Wikidata’s published figure of 7,910 km². This difference is flagged for review: a lake’s outline may include islands or bays that the published figure leaves out, or the water level may differ. The outline is kept because it is within 10%, and this page is not matched automatically to any other.

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.
