The deepest known point of the Mariana Trench, called Challenger Deep , is about 10,990–11,000 meters below sea level.

Key depth facts

  • Most modern measurements give a maximum depth of roughly 10,984 to 10,994 meters (about 36,037–36,070 feet).
  • This is just under 11 kilometers straight down from the ocean surface. At that depth, pressure is more than 1,000 times what it is at sea level.

Quick Scoop: perspective

  • If Mount Everest (8,848 meters) were placed into Challenger Deep, its summit would still be around 2,000 meters underwater.
  • The trench’s deepest region is a narrow valley on the seafloor rather than a simple “hole,” and measurements vary slightly depending on the method and expedition.
