How tall is Mount Everest? The most current and accurate answer is 8,848.86 meters (29,031.7 feet). This iconic measurement represents not just a geographical truth but also a symbol of human curiosity, technological advancement, and international cooperation.
Whether you're an aspiring trekker, a passionate geographer, or just curious, knowing the true Height of Mount Everest adds depth to the legend of this majestic Himalayan giant.
Mount Everest, known as Sagarmatha in Nepali and Chomolungma in Tibetan, holds the awe-inspiring title of the World's Highest Mountain. But how tall is Mount Everest exactly? The answer is both simple and fascinating, involving science, geography, and a bit of controversy.
The official height of Mount Everest is 8,848.86 meters (29,031.7 feet) above sea level. This measurement was jointly declared by Nepal and China in 2020, resolving a long-standing discrepancy between previous measurements.
This updated figure includes the snow cap on the summit, providing a more accurate and universally accepted height.
Over the years, Everest’s height has been calculated multiple times using increasingly advanced technology:
| Year | Measurement | Country/Agency |
|---|---|---|
| 1856 | 8,840 m (29,002 ft) | British Survey of India |
| 1955 | 8,848 m (29,029 ft) | Indian Government Survey |
| 1975 | 8,848.13 m (29,029 ft) | China Survey |
| 1999 | 8,850 m (29,035 ft) | U.S. GPS Survey (National Geographic) |
| 2020 | 8,848.86 m (29,031.7 ft) | Nepal & China Joint Survey |
The 2020 survey used Global Navigation Satellite Systems (GNSS) and ground-penetrating radar to measure both the rock height and the snow layer.
Yes, Mount Everest’s height is not fixed. Several factors cause subtle fluctuations:
Plate tectonics: Everest sits on the collision zone of the Indian and Eurasian plates, which causes it to rise a few millimeters every year.
Earthquakes: The 2015 Nepal earthquake slightly altered the mountain's structure, prompting further studies on its elevation.
Climate change: Melting glaciers and snow compaction may also influence summit height over time.
Height above sea level: 8,848.86 meters – the most accepted method globally.
Topographic prominence: Mount Everest also ranks as the most prominent peak in the world, standing dramatically above all nearby terrain.
Here’s how Everest compares to other giants:
| Rank | Mountain | Height (m) | Location |
|---|---|---|---|
| 1 | Mount Everest | 8,848.86 | Nepal/China |
| 2 | K2 (Mount Godwin-Austen) | 8,611 | Pakistan/China |
| 3 | Kangchenjunga | 8,586 | Nepal/India |
| 4 | Lhotse | 8,516 | Nepal/China |
| 5 | Makalu | 8,485 | Nepal/China |
No peak on Earth surpasses Mount Everest in sheer vertical elevation above sea level.
Understanding Everest’s precise height is more than a trivia fact—it’s crucial for:
Geological research and tectonic studies
Mountaineering logistics and oxygen planning
Tourism and mapping accuracy
International collaboration in science
If measured from the Earth’s center, Mount Chimborazo in Ecuador is technically farther from the core due to the equatorial bulge.
Everest’s summit grows approximately 4 mm per year due to plate movement.
The summit is in the death zone—an altitude above 8,000 meters where oxygen levels are dangerously low.
