Lebanon is 1.01× the size of Lake Onega

Lebanon (country) covers about 10,000 km² (3,860 mi²) and Lake Onega (lake) about 9,950 km² (3,840 mi²). Below, both outlines are drawn at one scale and centred on each other. The Lake Onega outline is Natural Earth’s, checked against the published area.

What fits

Lake Onega is 99% of the size of Lebanon.

How they differ

Their centres are about 3,100 km apart.
On a standard web map Lake Onega looks larger than Lebanon: Lebanon at 34°N is drawn about 1.5× too large and Lake Onega at 62°N about 4.5×, so the map shows Lake Onega as 3.06× the size of Lebanon, when Lebanon is 1.01× the size of Lake Onega.
Together Lebanon and Lake Onega cover 20,000 km², close to the size of Slovenia (20,300 km², 1.9% bigger).
Lake Onega's centre is 27.9° of latitude, about 3,100 km, farther north than Lebanon's.
Lebanon ranks 167th of 212 countries by area.
Lake Onega is a lake and ranks 17th of the 104 lakes on sizeversus by area.
Laid out flat, Lebanon stretches about 181 km north to south and 139 km east to west; Lake Onega about 230 km by 132 km.
Poured over Lebanon, the 285 km³ that Wikidata records for Lake Onega would stand 28 m deep.
Our measured 9,950 km² is 2.6% above Wikidata’s published figure of 9,700 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 Russia contain or lie within 4 km of the outline of Lake Onega. 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.
