Romania is 1.09× the size of Bay of Biscay

Romania (country) covers about 236,000 km² (91,300 mi²) and the Bay of Biscay (bay) about 216,000 km² (83,400 mi²). Below, both outlines are drawn at one scale and centred on each other. The Bay of Biscay outline is Natural Earth’s, checked against the published area.

How they differ

Their centres are about 2,270 km apart.
Together Romania and Bay of Biscay cover 452,000 km², close to the size of Yemen (453,000 km², 0.1% bigger).
The gap between them, 20,300 km², is about the size of Slovenia (20,300 km²).
Their centres lie at almost the same latitude.
Romania ranks 82nd of 212 countries by area.
The Bay of Biscay is a bay and ranks 25th of the 42 seas on sizeversus by area.
Laid out flat, Romania stretches about 516 km north to south and 735 km east to west; the Bay of Biscay about 571 km by 592 km.
Poured over Romania, the 389,000 km³ that Wikidata records for the Bay of Biscay would stand 1,646 m deep.
Our measured 216,000 km² is 3.1% below Wikidata’s published figure of 223,000 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 France and Spain lie within 25 km of the outline of the Bay of Biscay. 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.
