The numbers

9,030km²Area, measured3,490 mi² · Natural Earth outline
10,000km²Area, publishedWikidata · 9.7% 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 the Frobisher Bay

The Arabian Sea, the largest of the 42 seas ranked on sizeversus, is 457× the size of the Frobisher Bay; the Frobisher Bay ranks 42nd.
Counted as a country, the Frobisher Bay would be larger than 45 of the 212 countries listed on sizeversus and would rank 168th by area, between Lebanon (10,000 km²) and Palestine (6,070 km²).
It is larger than 3 of the 51 US states and districts (the biggest of them is Delaware, 5,170 km²) and smaller than 48.
It is larger than 1 of the 31 provinces and regions of China (the biggest of them is Shanghai, 6,750 km²) and smaller than 30.
The closest Chinese province is Tianjin (11,500 km²): the Frobisher Bay is 79% of the size of Tianjin.
On a standard web map (Web Mercator), a place at 63°N is drawn about 4.9× too large in area, so the Frobisher Bay looks bigger there than it is.
Laid out flat, the Frobisher Bay stretches about 172 km north to south and 170 km east to west.
Our measured 9,030 km² is 9.7% below Wikidata’s published figure of 10,000 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.

Natural Earth’s outlines of Canada lie within 25 km of the outline of the Frobisher Bay. 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 Marine Areas (geography_marine_polys), public domain (Marine Areas (geography_marine_polys)). Natural Earth draws marine areas for labels and cuts them at named sub-areas; the outline is kept because its area matches the published one.
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.
