The numbers
- 42,300km²Area, measured16,300 mi² · Natural Earth outline
- 41,200km²Area, publishedWikidata · 2.5% below our measure
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 Southampton Island
- Greenland (island), the largest of the 81 islands ranked on sizeversus, is 51.4× the size of Southampton Island; Southampton Island ranks 29th.
- Southampton Island sits between Berkner Island (43,600 km²) and Axel Heiberg Island (41,400 km²) in the ranking.
- Counted as a country, Southampton Island would be larger than 79 of the 212 countries listed on sizeversus and would rank 134th by area, between Denmark (42,700 km²) and Switzerland (41,400 km²).
- It is larger than 10 of the 51 US states and districts (the biggest of them is Maryland, 25,500 km²) and smaller than 41.
- It is larger than 4 of the 31 provinces and regions of China (the biggest of them is Hainan, 33,800 km²) and smaller than 27.
- The closest Chinese province is Ningxia (52,100 km²): Southampton Island is 81% of the size of Ningxia.
- On a standard web map (Web Mercator), a place at 64°N is drawn about 5.3× too large in area, so Southampton Island looks bigger there than it is.
- Laid out flat, Southampton Island stretches about 310 km north to south and 341 km east to west.
- Our measured 42,300 km² is 2.5% above Wikidata’s published figure of 41,200 km². Published areas of lakes and seas move with the water level and with what is counted, so a few percent is expected.

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.
