What the numbers say about Lagoa Mirim
- The Caspian Sea (called a sea or a lake, depending on the definition), the largest of the 104 lakes ranked on sizeversus, is 98.7× the size of Lagoa Mirim; Lagoa Mirim ranks 41st.
- Lagoa Mirim sits between Dubawnt Lake (3,850 km²) and Sarygamysh Lake (3,820 km²) in the ranking.
- Counted as a country, Lagoa Mirim would be larger than 40 of the 212 countries listed on sizeversus and would rank 173rd by area, between Cape Verde (3,930 km²) and Turkish Republic of Northern Cyprus (3,320 km²).
- It is larger than 2 of the 51 US states and districts (the biggest of them is Rhode Island, 2,830 km²) and smaller than 49.
- It is smaller than every one of the 31 provinces and regions of China.
- The closest US state is Delaware (5,170 km²): Lagoa Mirim is 74% of the size of Delaware.
- Wikidata records a greatest depth of 12 m.
- Its surface lies about 1 m above sea level (Wikidata).
- On a standard web map (Web Mercator), a place at 33°S is drawn about 1.4× too large in area, so Lagoa Mirim looks bigger there than it is.
- Laid out flat, Lagoa Mirim stretches about 157 km north to south and 99 km east to west.
- Our measured 3,840 km² is 3.8% below Wikidata’s published figure of 3,990 km². Published areas of lakes and seas move with the water level and with what is counted, so a few percent is expected.

On the shore
Natural Earth’s outlines of Brazil and Uruguay contain or lie within 4 km of the outline of Lagoa Mirim. 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 Lagoa Mirim ranks
Lagoa Mirim is the 41st 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.
