Adriatic Sea is 1.01× the size of Anhui

The Adriatic Sea (sea) covers about 141,000 km² (54,400 mi²) and Anhui (province) about 140,000 km² (54,100 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.

What fits

Anhui is 99% of the size of Adriatic Sea.
Adriatic Sea is larger by 755 km² (292 mi²), which is 0.5% of the area of Anhui.
Measured in Belgiums: Adriatic Sea is about 4.60, Anhui about 4.57.

How they differ

Their centres are about 8,480 km apart.
A standard web map misstates the comparison: Adriatic Sea at 43°N is drawn about 1.9× too large and Anhui at 32°N about 1.4×, so the map shows Adriatic Sea as 1.35× the size of Anhui instead of 1.01×.
Together Adriatic Sea and Anhui cover 281,000 km², close to the size of Burkina Faso (273,000 km², 3.0% smaller).
Adriatic Sea's centre is 10.9° of latitude, about 1,210 km, farther north than Anhui's.
The Adriatic Sea is a sea and ranks 27th of the 42 seas on sizeversus by area.
Anhui is a province of China; it is not drawn with its waters removed, and its measured area is the Natural Earth outline's.
Laid out flat, the Adriatic Sea stretches about 668 km north to south and 637 km east to west; Anhui about 582 km by 448 km.
Wikidata’s published figure of 139,000 km² agrees with our measured 141,000 km², to within 2%.

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.
