- 84,400km²Area, publishedWikidata · 3.3% above 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 Ireland (island)
- Greenland (island), the largest of the 81 islands ranked on sizeversus, is 26.6× the size of Ireland (island); Ireland (island) ranks 19th.
- Ireland (island) sits between Mindanao (92,000 km²) and Hokkaidō (77,100 km²) in the ranking.
- Counted as a country, Ireland (island) would be larger than 97 of the 212 countries listed on sizeversus and would rank 116th by area, between Austria (84,000 km²) and Czechia (78,800 km²).
- It is larger than 12 of the 51 US states and districts (the biggest of them is South Carolina, 80,200 km²) and smaller than 39.
- It is larger than 5 of the 31 provinces and regions of China (the biggest of them is Ningxia, 52,100 km²) and smaller than 26.
- The closest Chinese province is Chongqing (82,400 km²): Ireland (island) is about the same size as Chongqing.
- On a standard web map (Web Mercator), a place at 53°N is drawn about 2.8× too large in area, so Ireland (island) looks bigger there than it is.
- Laid out flat, Ireland (island) stretches about 431 km north to south and 327 km east to west.
- Our measured 81,600 km² is 3.3% below Wikidata’s published figure of 84,400 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.
