The numbers

The area is measured from the outline drawn above, on the WGS84 ellipsoid; the published figure is shown beside it, and a water body is kept only if the two are within 10%.

What the numbers say about Sardinia

About the same size as

Where it lies

Natural Earth’s outlines of Italy contain or lie within 4 km of the outline of Sardinia. That is what its geometry says, and it is not a statement about who owns the water or where any border runs in it.

Outline of Sardinia, about 23,800 km², drawn to true scale
Outlines are drawn at true scale.
Sources and method
Outline
Natural Earth, 1:10m Geography Regions (geography_regions_polys), public domain (Geography Regions (geography_regions_polys)). Outlines of lakes are drawn at 1:10 million.
Boundary
A lake or a sea has no legal boundary of its own. The outline is a cartographic one, and the page says so by showing the measured area beside the published one.
Area basis
Measured outline: computed on the WGS84 ellipsoid from the full-detail outline and shown rounded. Published figure: Wikidata (CC0), fetched 2026-11-11. An outline is kept within 10% of the published figure and matched to other places automatically within 5%.
Shore
Countries whose Natural Earth outline contains or comes close to the water's outline; computed, not a statement of ownership.
Drawing
Each outline is projected with an equal-area projection centred on its own centroid, so areas stay true and two can be laid over each other.
