What the numbers say about the White Sea
- The Arabian Sea, the largest of the 42 seas ranked on sizeversus, is 44.8× the size of the White Sea; the White Sea ranks 30th.
- The White Sea sits between the Savu Sea (102,000 km²) and the Bohai Sea (77,900 km²) in the ranking.
- Counted as a country, the White Sea would be larger than 102 of the 212 countries listed on sizeversus and would rank 111th by area, between Hungary (93,200 km²) and Portugal (91,400 km²).
- It is larger than 13 of the 51 US states and districts (the biggest of them is Maine, 84,300 km²) and smaller than 38.
- It is larger than 6 of the 31 provinces and regions of China (the biggest of them is Chongqing, 82,400 km²) and smaller than 25.
- The closest US state is Indiana (94,300 km²): the White Sea is about the same size as Indiana.
- Wikidata records a greatest depth of 330 m; with its volume that gives an average depth of about 48 m.
- Wikidata records a volume of 4,400 km³. Poured over Portugal (91,400 km²), that water would stand 48 m deep.
- On a standard web map (Web Mercator), a place at 66°N is drawn about 6.2× too large in area, so the White Sea looks bigger there than it is.
- Laid out flat, the White Sea stretches about 545 km north to south and 547 km east to west.
- Wikidata’s published figure of 90,800 km² agrees with our measured 92,200 km², to within 2%.

On the shore
Natural Earth’s outlines of Russia lie within 25 km of the outline of the White Sea. 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%.
- 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.
