Equatorial Guinea is 1.02× the size of Great Slave Lake

Equatorial Guinea (country) covers about 26,700 km² (10,300 mi²) and Great Slave Lake (lake) about 26,100 km² (10,100 mi²). Below, both outlines are drawn at one scale and centred on each other. The Great Slave Lake outline is Natural Earth’s, checked against the published area.

What fits

Great Slave Lake is 98% of the size of Equatorial Guinea.
Equatorial Guinea is larger by 576 km² (223 mi²), which is 2.2% of the area of Great Slave Lake.
Measured in Belgiums: Equatorial Guinea is about 0.87, Great Slave Lake about 0.85.

How they differ

Their centres are about 11,600 km apart.
On a standard web map Great Slave Lake looks larger than Equatorial Guinea: Equatorial Guinea at 2°N is drawn about 1.0× too large and Great Slave Lake at 62°N about 4.5×, so the map shows Great Slave Lake as 4.35× the size of Equatorial Guinea, when Equatorial Guinea is 1.02× the size of Great Slave Lake.
Together Equatorial Guinea and Great Slave Lake cover 52,800 km², close to the size of Bosnia and Herzegovina (51,800 km², 1.8% smaller).
The gap between them, 576 km², is about the size of Isle of Man (575 km²).
Great Slave Lake's centre is 60.0° of latitude, about 6,670 km, farther north than Equatorial Guinea's.
Equatorial Guinea ranks 147th of 212 countries by area.
Great Slave Lake is a lake and ranks 10th of the 104 lakes on sizeversus by area.
Laid out flat, Equatorial Guinea stretches about 583 km north to south and 636 km east to west; Great Slave Lake about 222 km by 417 km.
Poured over Equatorial Guinea, the 1,580 km³ that Wikidata records for Great Slave Lake would stand 59 m deep.
Our measured 26,100 km² is 4.1% below Wikidata’s published figure of 27,200 km². Published areas of lakes and seas move with the water level and with what is counted, so a few percent is expected.

Published figures: Wikidata (CC0). A lake or a sea has no legal boundary: the measured area is that of Natural Earth’s outline, and it is shown beside the published one.

Natural Earth’s outlines of Canada contain or lie within 4 km of the outline of Great Slave Lake. 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

Outlines: Lakes and seas: Natural Earth 1:10m physical vectors (public domain), kept only where the measured area is within 10% of the published one. Countries and regions: Natural Earth, 1:10m Admin 0 and Admin 1, public domain.
Boundary: De facto, as drawn by Natural Earth. A lake or a sea has no legal boundary of its own; the outline is a cartographic one.
Area: Measured on the WGS84 ellipsoid from the full-detail outlines, shown rounded. The published figure comes from Wikidata (CC0), fetched 2026-11-11, and is shown beside the measured one.
Drawing: Each outline is projected with an equal-area projection centred on its own centroid, so areas stay true and the two can be laid over each other.
