How big is a Sequoia tree?

Sequoia trees, specifically the giant sequoias (Sequoiadendron giganteum), can grow to impressive heights, often reaching between 164 to 279 feet (50 to 85 meters) tall. They also have massive trunks, with diameters that can exceed 30 feet (9 meters) at the base. The oldest living sequoias can be over 3,000 years old, making them some of the largest and longest-living trees on Earth. The combination of their height, girth, and age makes them a remarkable natural phenomenon.
