South Island is 1.12× the size of Greece

South Island (island) covers about 147,000 km² (56,800 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 South Island outline is Natural Earth’s, checked against the published area.

What fits

Greece is 89% of the size of South Island.
South Island is larger by 15,800 km² (6,120 mi²), which is 12% of the area of Greece.
Measured in Belgiums: South Island is about 4.80, Greece about 4.28.

How they differ

Their centres are about 17,300 km apart.
A standard web map misstates the comparison: South Island at 44°S is drawn about 1.9× too large and Greece at 39°N about 1.7×, so the map shows South Island as 1.31× the size of Greece instead of 1.12×.
Together South Island and Greece cover 279,000 km², close to the size of Burkina Faso (273,000 km², 2.1% smaller).
The gap between them, 15,800 km², is about the size of East Timor (15,100 km²).
Greece's centre is 83.0° of latitude, about 9,230 km, farther north than South Island's.
South Island is an island and ranks 11th of the 81 islands on sizeversus by area.
Greece ranks 97th of 212 countries by area.
Laid out flat, South Island stretches about 679 km north to south and 630 km east to west; Greece about 761 km by 757 km.
Our measured 147,000 km² is 2.1% below Wikidata’s published figure of 150,000 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 New Zealand contain or lie within 4 km of the outline of South Island. 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.
