Which mountain has the highest base-to-peak height on Earth?
Quick Answer

The Full Story
Mauna Kea on the island of Hawaiʻi is widely regarded as the tallest mountain on Earth when measured from its base on the seafloor to its summit. It rises about 10,210 meters, or roughly 33,500 feet, from the ocean floor, even though its summit is only 4,207 meters above sea level. By contrast, Mount Everest is the highest mountain above sea level at 8,849 meters. Mauna Kea’s great height is a reminder that “tallest” and “highest above sea level” are not the same measurement.
