how tall is mauna kea
Mauna Kea is about 4,207 meters (13,803 feet) above sea level , but if you measure it from its base on the Pacific Ocean floor, it rises to roughly 10,200 meters (about 33,500 feet) , making it taller than Everest by that base‑to‑summit measure.
Quick Scoop
- Height above sea level: About 4,207–4,208 meters (13,796–13,803 feet), the highest point in Hawaii.
- Height from underwater base: Around 10,200 meters (≈33,500 feet), which is taller than Mount Everest when measured base to peak.
- Why the numbers differ: Some sources round slightly differently (13,796 vs. 13,803 ft; 4,205 vs. 4,207 m), but they all agree Mauna Kea is Hawaii’s highest summit and an extremely tall mountain when measured from the seafloor.
Mauna Kea vs. Everest (Height Perspective)
| Mountain | Above sea level | Base-to-peak idea |
|---|---|---|
| Mauna Kea | ≈4,207 m / 13,803 ft | [9][1][3][7]≈10,200 m / 33,500 ft from ocean floor | [3][5][7]
| Mount Everest | ≈8,849 m / 29,032 ft above sea level | [7][3]Usually measured only from sea level, not from a deep underwater base | [3][7]
Why People Call It the “Tallest”
From a climber’s usual perspective , height is measured above sea level, so Everest is higher than Mauna Kea in that common sense. But from a geologist’s perspective , if you include the part hidden under the ocean, Mauna Kea’s full volcanic structure is taller than Everest’s rise above sea level, which is why it’s often described as the world’s tallest mountain from base to summit.
TL;DR:
Mauna Kea’s summit is about 4.2 km above sea level, but the volcano itself
stretches roughly 10.2 km from the Pacific seafloor to the top, making it an
underwater giant that can fairly claim to out‑tower Everest when measured from
base to peak.
