The General Sherman Tree is the world's largest tree, measured by volume. It stands 275 feet (83 m) tall, and is over 36 feet (11 m) in diameter at the base. Sequoia trunks remain wide high up. Sixty feet above the base, the Sherman Tree is 17.5 feet (5.3 m) in diameter.
A giant sequoia, the tree is believed to be between 2,300 and 2,700 years old and its largest branches are wider in diameter than most regular tree trunks.
General Sherman has held the title of world's largest tree since 1931 after a team of engineers, led by J. W. Jourdan of the San Joaquin Light and Power Corporation, measured the four then-largest-known redwoods (Boole, Hart, General Grant, and General Sherman) and determined that General Sherman was the true size champion.
