Taller than high
Mt. Everest isn't the tallest mountain in the world. Really. It's the highest. The world's tallest mountain is Mauna Kea. Because it's on an island, its height is measured from the ocean floor. So, although its altitude is only 4205 meters (Everest's is 8848 meters), Mauna Kea is more than 10,000 meters tall. Everest's height, measured on dry land, is the same as its altitude, more than 1000 meters less than Mauna Kea's.
