Mount Everest is 8,848.86 meters (about 29,032 feet) tall, making it the highest mountain on Earth above sea level. That official height comes from a joint survey by Nepal and China announced in 2020, and it includes the summit’s snow cap.
Everest sits in the Mahalangur Himal section of the Himalayas, and its summit marks part of the border between Nepal and China (Tibet).
