This is what the world would look like if it were only made of islands:
Here are a few more facts about the islands above:
- Canada fully owns 5 of the top 26 islands, while Indonesia owns all or part of 5 as well.
- The most populated island is Indonesia’s Java with 143 million people.
- The least populated is Canada’s Banks Island with just 136.
- The United States does not have a single island in the top 26, with the largest being Hawai’i (Big Island), which is only the 76th largest in the world.
- Only 4 islands belong to more than one country – New Guinea, Borneo, Ireland and Hispaniola
Why isn’t Australia considered an island?
Technically every continent in the world could be considered an island. Australia is 3 times the size of Greenland and is the largest landmass on its continental shelf. Thus, it can be considered an island-continent, but most often it’s classed as a continent rather than an island.
In fact, if it was an island it would be roughly as large as the next 26 combined.

Brilliant Maps says
I’ve looked into a bit more and the original map creator defined islands as anything that weren’t continents, so they’ve excluded Australia (island) because it’s the largest land mass in Australia (continent).
I think this makes a certain amount of sense as it would make comparisons difficult, due to the scale you’d have to use (Australia being 3X the size of Greenland).
Keivan Hadji Hossein says
Think about Africa and Antarctica: their main landmasses measure respectively 29.7 million km2 (Madagascar excluded) and 14 million km2. They’re detached from other continents and they do have a large number of islands that are still considered part of their continents. Nevertheless, their landmasses are never considered to be “islands” on their own. Same goes for Australia (excluding Tasmania): it actually is Oceania’s main landmass rather than a simple island.
Ken says
Africa is not “detached from other continents”. It simply became physically discontiguous with Eurasia when a canal was dug a few generations ago.
Juan Pérez says
Only 4 islands belong to more than one country – New Guinea, Borneo, Ireland and Hispaniola**** There are at least 5 considering Tierra del Fuego Island.
Answerer says
Actually there are seven significant islands with borders: the five you mentioned, plus Timor (whose estarn part gained independence from Indonesia) and Cyprus (whose nothen third was invaded by turkish scum). Other divided islands are smaller at least fifteen times Cyprus and scarcely inhabited, so their relevance is much less.
Dan says
Don’t forget Great Britain—home to England, Scotland and Wales
NEU Engineering CC says
If Australia isn’t an Island then how come Christine Anu sings about “My Island Home?”
drooghead says
She grew up in Cairns and the Torres Strait islands so the island she is referring to is not the Australian mainland but the Torres Strait islands.
Jo says
I disagree, it is because most Australians regard the country as an island. Cairns is on the mainland…. proof, her lyrics say “My home is Australia. We are a land bound by sea. Though I may travel far across the ocean, it will never forget me…. My island home, my island home, my island home is waiting for me”.
mP says
She could be singing about the many islands off the Queensland coast.
NEU Engineering CC says
New Zealand’s South Island is (mostly) on the Pacific plate. It is the largest land mass on that plate, is it an contitnent too?
Sawdust says
Actually, there is some talk recently about exactly this point…that New Zealand could be considered a (small) continent!
Aussieeee says
Australia is a country not a continent…
i usually call the continent oceania
sooooo whadda bout now?
R. Snider says
On the topic of islands owned by two countries, I believe you forgot Sint Maarten/St. Martin owned by the Netherlands and France.
Ken says
There a five bullet point below the heading listing “a few more facts about the islands above”. Those islands above are the 26 largest islands, so Märket and Saint Martin are not included, as they are too small.
Rick Tavares says
Also St Martin
Drake says
Why do some publications flip Victoria Island and Great Britain on these lists? They are fairly close in area, but there seems to be some disagreement about which one should be first.
Jeff says
It depends whether the tide is in or out 😉
Shuhananabinkinsha says
I know right!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Shubananadinkinsha says
The map was very cool, but you did not answer my question of where Wales ranks on the scale of islands.
Emma says
There is no Victoria Island. It is Vancouver Island.
Brilliant Maps says
https://en.wikipedia.org/wiki/Victoria_Island_(Canada)
TR says
Victoria Island is in NWT and is far larger than Vancouver Island.
Wayne Dobson says
Victoria is in the Arctic They missed Vancouver completely!
Dan says
Vancouver Island is about half the size of Tasmania, the smallest island on this list.
Larry Vandiver says
As a third grader in 1952, we were taught that Australia was the Island Continent. Yes, I’m old, but I do remember Mrs. Myer, my third grade teacher telling us that. It was also referred to as the Land Down Under.
Sarah says
You are correct Larry
e says
What about Newfoundland, Canada. The island part is 108,890 kms sq. Population 525,073 in 2018.
