Want to know which is the world’s biggest island? Here’s a list of the largest islands in the world, ranked by their total area in square miles and square kilometers.
Greenland is the largest island in the world with an area of (840,004 sq. miles) (2,175,600 sq. km). It’s an arctic island, which is part of the Kingdom of Denmark, which technically makes Denmark one of the biggest countries in the world if you include the size of Greenland.
Despite its name, it’s not very green considering that it’s covered in snow and ice most of the year. The capital city of Nuuk is home to almost 1/4 of the total population of Greenland. The majority of Greenlanders are Inuit or a mix of Danish and Inuit.
The island of New Guinea is the second-largest island in the world, and it’s divided in half by Indonesia (West Papua) and Papua New Guinea.
The whole island has an area of (303,381 sq. miles) (785,753 sq. km), which makes it half the size of Greenland, although it’s still a very big island that is home to more than 11 million people.
Borneo is famous for being home to Orangutans, one of the closest relatives to humans. But the island is also ranked as the third-largest island in the world with an area of (288,869 sq. miles) (748,168 sq. km).
It’s shared between Malaysia, Indonesia, and Brunei.
Madagascar is the largest island in Africa and has a total area of (226,917 sq. miles) (587,713 sq. km). It’s particularly known for its incredibly biodiverse flora and fauna, which is believed to have happened because of its isolated position for millions of years.
Madagascar is home to chameleons and the lemurs as well as the majestic Baobab trees.
Baffin Island is another arctic island that is known for its big size. It belongs to Canada and the Nunavut territory in the northern part of the country.
The island has a total area of (194,574 sq. miles) (503,944 sq. km), which makes it one of the largest islands in the world!

More about the Largest Islands in the World
Some of the largest islands in the world are largely uninhabited such as Greenland and Baffin Island.
But some are home to quite large populations, such as New Guinea with 11 million people, and Great Britain especially, which is home to more than 67 million people despite only being the 9th largest island in the world.
Honshu (Japan), Java (Indonesia), and Luzon (Philippines) are other examples of the most populous islands in the world.
Most of the largest islands in the world are located in the arctic region, Oceania, or Asia. If you look at the top 15 biggest islands, 7 of them are located on the Asian continent, whereas Africa only has 1 island on the list.
