About this ranking

Where an island ends and a continent begins is a convention. Australia, at about 7.7 million km², is treated as a continent, which makes Greenland the largest island. Each area is for the main island alone, without the smaller islands around it.

Areas and countries come from the English Wikipedia list (CC BY-SA 4.0); names in each language come from Wikidata (CC0). Islands off Antarctica belong to no country and show a dash.
