Adriatic Sea is 1.07× the size of Greece

The Adriatic Sea (sea) covers about 141,000 km² (54,400 mi²) and Greece (country) about 131,000 km² (50,700 mi²). Below, both outlines are drawn at one scale and centred on each other. The Adriatic Sea outline is Natural Earth’s, checked against the published area.

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 Italy, Croatia, Albania, Bosnia and Herzegovina, Greece, Montenegro and Slovenia lie within 25 km of the outline of the Adriatic 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

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.
