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 Topozero
- The Caspian Sea (called a sea or a lake, depending on the definition), the largest of the 104 lakes ranked on sizeversus, is 365× the size of Topozero; Topozero ranks 96th.
- Topozero sits between O'Higgins/San Martín Lake (1,050 km²) and Lake Chapala (1,030 km²) in the ranking.
- Counted as a country, Topozero 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): Topozero is 37% of the size of Rhode Island.
- Wikidata records a greatest depth of 56 m; with its volume that gives an average depth of about 15 m.
- Wikidata records a volume of 16 km³. Poured over São Tomé and Príncipe (1,040 km²), that water would stand 15 m deep.
- Its surface lies about 109 m above sea level (Wikidata).
- On a standard web map (Web Mercator), a place at 66°N is drawn about 5.9× too large in area, so Topozero looks bigger there than it is.
- Laid out flat, Topozero stretches about 59 km north to south and 58 km east to west.
- Our measured 1,040 km² is 5.5% above Wikidata’s published figure of 986 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 Russia contain or lie within 4 km of the outline of Topozero. That is what its geometry says, and it is not a statement about who owns the water or where any border runs in it.

Where Topozero ranks
Topozero is the 96th largest of the 104 lakes on sizeversus, ranked by measured area.
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.
