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 the Gulf of Saint Lawrence

• The Arabian Sea, the largest of the 42 seas ranked on sizeversus, is 17.0× the size of the Gulf of Saint Lawrence; the Gulf of Saint Lawrence ranks 23rd.
• The Gulf of Saint Lawrence sits between the Persian Gulf (243,000 km²) and the Molucca Sea (217,000 km²) in the ranking.
• Counted as a country, the Gulf of Saint Lawrence would be larger than 133 of the 212 countries listed on sizeversus and would rank 80th by area, between the United Kingdom (244,000 km²) and Uganda (242,000 km²).
• It is larger than 40 of the 51 US states and districts (the biggest of them is Minnesota, 225,000 km²) and smaller than 11.
• It is larger than 23 of the 31 provinces and regions of China (the biggest of them is Guangxi, 237,000 km²) and smaller than 8.
• The closest Chinese province is Guangxi (237,000 km²): the Gulf of Saint Lawrence is about the same size as Guangxi.
• Wikidata records a greatest depth of 530 m; with its volume that gives an average depth of about 142 m.
• Wikidata records a volume of 34,500 km³. Poured over the United Kingdom (244,000 km²), that water would stand 142 m deep.
• On a standard web map (Web Mercator), a place at 48°N is drawn about 2.3× too large in area, so the Gulf of Saint Lawrence looks bigger there than it is.
• Laid out flat, the Gulf of Saint Lawrence stretches about 656 km north to south and 888 km east to west.
• Our measured 242,000 km² is 7.2% above Wikidata’s published figure of 226,000 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.

• Canada
• Saint Pierre and Miquelon

Natural Earth’s outlines of Canada and Saint Pierre and Miquelon lie within 25 km of the outline of the Gulf of Saint Lawrence. That is what its geometry says, and it is not a statement about who owns the water or where any border runs in it.
