What is the smallest continent by land area?

Australia is the smallest continent by area, with an area of roughly 7.7 million square kilometers (3 million square miles).
Sometimes people also use the name Oceania to describe a larger region that includes Australia, New Zealand, Papua New Guinea, and other islands in the Pacific. If we used the area of Oceania as a continent, it would be a little larger than just Australia, with an area of about 8.5 to 9 million square kilometers. But in the traditional seven continent model that is largely used throughout the world, Australia is recognized as the smallest continent by area.
