Sakhalin is 1.07× the size of Ireland

Sakhalin (island) covers about 74,500 km² (28,800 mi²) and Ireland (country) about 69,400 km² (26,800 mi²). Below, both outlines are drawn at one scale and centred on each other. The Sakhalin outline is Natural Earth’s, checked against the published area.

What fits

Ireland is 93% of the size of Sakhalin.
Sakhalin is larger by 5,040 km² (1,950 mi²), which is 7.3% of the area of Ireland.
Measured in Belgiums: Sakhalin is about 2.43, Ireland about 2.26.

How they differ

Their centres are about 8,200 km apart.
On a standard web map Ireland looks larger than Sakhalin: Sakhalin at 50°N is drawn about 2.4× too large and Ireland at 53°N about 2.8×, so the map shows Ireland as 1.06× the size of Sakhalin, when Sakhalin is 1.07× the size of Ireland.
Together Sakhalin and Ireland cover 144,000 km², close to the size of Suriname (145,000 km², 0.8% bigger).
The gap between them, 5,040 km², is about the size of Trinidad and Tobago (5,120 km²).
Ireland's centre is 2.9° of latitude, about 320 km, farther north than Sakhalin's.
Sakhalin is an island and ranks 21st of the 81 islands on sizeversus by area.
Ireland ranks 122nd of 212 countries by area.
Laid out flat, Sakhalin stretches about 945 km north to south and 219 km east to west; Ireland about 437 km by 303 km.
Our measured 74,500 km² is 2.8% above Wikidata’s published figure of 72,500 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 Sakhalin. 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.
