The numbers
- 20,800km²Area, measured8,050 mi² · Natural Earth outline
- 22,200km²Area, publishedWikidata · 6.1% 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 Peloponnese
- Greenland (island), the largest of the 81 islands ranked on sizeversus, is 104× the size of Peloponnese; Peloponnese ranks 44th.
- Peloponnese sits between Kotelny Island (22,400 km²) and Shikoku (18,100 km²) in the ranking.
- Counted as a country, Peloponnese would be larger than 60 of the 212 countries listed on sizeversus and would rank 153rd by area, between Djibouti (21,800 km²) and El Salvador (20,500 km²).
- It is larger than 6 of the 51 US states and districts (the biggest of them is New Jersey, 19,700 km²) and smaller than 45.
- It is larger than 3 of the 31 provinces and regions of China (the biggest of them is Beijing, 16,300 km²) and smaller than 28.
- The closest US state is Massachusetts (21,200 km²): Peloponnese is about the same size as Massachusetts.
- On a standard web map (Web Mercator), a place at 38°N is drawn about 1.6× too large in area, so Peloponnese looks bigger there than it is.
- Laid out flat, Peloponnese stretches about 209 km north to south and 208 km east to west.
- Our measured 20,800 km² is 6.1% below Wikidata’s published figure of 22,200 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.

Where it lies
Natural Earth’s outlines of Greece contain or lie within 4 km of the outline of Peloponnese. That is what its geometry says, and it is not a statement about who owns the water or where any border runs in it.

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.
