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 Lake Sevan
- The Caspian Sea (called a sea or a lake, depending on the definition), the largest of the 104 lakes ranked on sizeversus, is 275× the size of Lake Sevan; Lake Sevan ranks 75th.
- Lake Sevan sits between Lake Milh (1,430 km²) and Khyargas Nuur (1,350 km²) in the ranking.
- Counted as a country, Lake Sevan would be larger than 35 of the 212 countries listed on sizeversus and would rank 178th by area, between the Comoros (1,670 km²) and São Tomé and Príncipe (1,040 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): Lake Sevan is 49% of the size of Rhode Island.
- Wikidata records a greatest depth of 81 m; with its volume that gives an average depth of about 27 m.
- Wikidata records a volume of 37 km³. Poured over the Comoros (1,670 km²), that water would stand 22 m deep.
- Its surface lies about 1,900 m above sea level (Wikidata).
- On a standard web map (Web Mercator), a place at 40°N is drawn about 1.7× too large in area, so Lake Sevan looks bigger there than it is.
- Laid out flat, Lake Sevan stretches about 54 km north to south and 60 km east to west.
- Our measured 1,380 km² is 8.5% above Wikidata’s published figure of 1,270 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.

On the shore
Natural Earth’s outlines of Armenia contain or lie within 4 km of the outline of Lake Sevan. 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 Lakes + Reservoirs, public domain (Lakes + Reservoirs). 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%.
- Depth, volume, height
- As recorded in Wikidata; a volume that cannot be right for the area and depth is left out.
- 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.
