In order of size, the largest of the oceans is the Pacific Ocean, followed by the Atlantic Ocean, the Indian Ocean, the Southern Ocean and the Arctic Ocean. To give an idea of the range of size, the Pacific Ocean extends for 60 million square miles, while the Arctic Ocean is a mere 5.4 million sq miles. The deepest point in the world's oceans is the Mariana Trench in the Pacific Ocean off the coast of Japan. There is some disagreement as to its precise depth, but it is somewhere close to 36,000 feet, or 6.8 miles.
How big is the Atlantic Ocean? The Atlantic Ocean covers an area of approximately 41,105,000 square miles. As the second largest ocean basin, the Atlantic Ocean borders the east coast of the U.S., while the Pacific, Earth's largest ocean basin, borders the U.S. West Coast. Covering approximately 20 percent of the Earthâs surface, the Atlantic Ocean is the second largest ocean basin in the world, following only the Pacific. However, it is only slightly larger than half the size of the Pacific Ocean. The Atlantic Ocean lies between North and South America on the west and Europe and Africa on the east. Up north, the Atlantic connects to the Arctic Ocean and to the Southern Ocean to the south.
