Islands at true size, beside the countries they match
Natural Earth outlines 294 islands, and a further set of island-group shapes that are drawn for labels (Polynesia is 33 million km²) and are not used. Each island here has been measured on the ellipsoid and checked against its published area, and the 81 with pages passed. Below they are drawn at true scale and matched to the country nearest each in size.
This page is about size, not about borders or names. A lake or a sea has no legal boundary of its own, so the outlines are cartographic ones, and every area is shown beside the published figure it was checked against.
The largest, at one scale
Every outline is drawn at the same scale; select one to open its page.
At a glance
- Greenland (island), the largest of the 81 islands on sizeversus, is 2.80× the size of New Guinea, the next, and 868× the size of Réunion, the smallest.
- The ten largest cover 5,790,000 km² together, 75% of the size of Australia.
- 37 of the 81 are larger than Belgium (30,700 km²).
- 23 of the 81 are larger than Ireland (69,400 km²).
- 18 of the 81 are larger than Austria (84,000 km²).
- Greenland (island) alone is larger than 201 of the 212 countries on sizeversus, and than 51 of the 51 US states and districts.
- The three largest, Greenland (island), New Guinea, Borneo, are 3,671,000 km² together.
- Natural Earth draws coastlines at 1:10 million, so island outlines measure 1% to 5% below the published areas; 22 of the 81 are flagged because they are more than 5% off, and 122 outlines were left out.
Every island matched to a country
Largest first. The match is the country closest in area from Natural Earth’s country list (contested places and dependencies are never used), and the second is the closest US state or Chinese province, or else the closest island, when one is within a factor of 3. A flag means the outline is more than 5% from the published area.

The closest matches in size
Left out, and why
122 outlines were measured and not kept: either the outline differs from the published area by more than 10%, or Wikidata has no published area to check it against. The largest, with the reason:

|---|---|---|---|---|
| Sumatra | 424,000 | 473,000 | -10.5% | outline differs |

Sources and method
- Outlines
- Natural Earth, 1:10m Geography Regions (geography_regions_polys), public domain. Lakes and reservoirs, marine areas and island outlines are three Natural Earth files; countries for the matches come from Natural Earth's Admin 0 file.
- What was checked
- Every outline was measured on the WGS84 ellipsoid and compared with the area Wikidata (CC0) publishes for it, fetched 2026-11-11. Within 2% it agrees, within 5% it is near, within 10% it is kept and flagged; beyond that, or with no published area, it is left out.
- Pieces
- Where Natural Earth draws a sea or a lake system in several outlines, the pieces are named in
config/waters.jsonand counted together only if their sum agrees with the published area of the whole. An outline that lies mostly inside a larger lake (Georgian Bay in Lake Huron) is counted once, in the larger one. - Boundary
- A lake or a sea has no legal boundary. The outlines are cartographic, and the pages say so.
