Discover the astonishing world of giant trees—from record-breaking redwoods to legendary sequoias—and the science and stories behind these global icons.

The World’s Largest Trees: Giants That Shape Our Forests

Across the planet, massive trees stand as some of nature’s most awe-inspiring wonders. For centuries, they have captivated poets, scientists, and travelers—offering shade, shelter, stories, and ecological stability. But which trees claim the title of largest in the world, and how do they measure up in terms of height, volume, age, and global significance?

How Do We Define ‘Largest’?

The term ‘largest tree’ can refer to several different measurements:

Height: The tree that reaches the greatest vertical extent.
Trunk Volume: The amount of wood in the main stem (excluding branches and roots).
Diameter or Circumference: The thickness of the trunk at a specified height above ground.
Age: Oldest living trees or forests.

Most records focus on height or trunk volume, but each metric tells a different story about a tree’s grandeur and ecological role.

General Sherman: The Largest Tree by Volume

In California’s Sequoia National Park stands the General Sherman Tree, widely recognized as the largest tree on Earth by trunk volume. This giant sequoia (Sequoiadendron giganteum) towers at 275 feet (83.8 meters), with an estimated trunk volume of 52,508 cubic feet (1,487 cubic meters). Its base diameter measures over 36 feet (11 meters), making it a true titan of the natural world.

Location: Sequoia National Park, California
Height: 275 feet (83.8 m)
Trunk Volume: 52,508 cubic feet (1,487 m³)
Estimated Weight: Over 2,000 tons
Diameter at Base: 36 feet (11 m)

General Sherman’s immense size is a product of California’s unique climate—mild winters, deep snowpack, and historic fire cycles—all of which create ideal conditions for sequoia growth. Despite their enormous size today, sequoias once ranged much more widely across North America and Europe, but now remain primarily on the western slopes of the Sierra Nevada.

General Grant and the President Tree: Other Volume Giants

Beyond General Sherman, the Sierra Nevada hosts several other massive trees:

General Grant Tree: Second-largest by trunk volume (46,608 cubic feet or 1,320 cubic meters).
President Tree: When branch volume is included, the President Tree may rival or exceed the Grant Tree, thanks to its sprawling crown and massive branches.

Measurement notes: Volume calculations typically exclude branches and roots, but comprehensive studies (like those published by National Geographic) highlight how branch volume can also contribute significantly to total size.

Hyperion: The World’s Tallest Living Tree

While sequoias dominate the volume records, coast redwoods (Sequoia sempervirens) reach even greater heights. The tallest living specimen is Hyperion, standing at an astonishing 380 feet (115.6 meters) in Redwood National Park, California.

Location: Redwood National Park, California
Height: 380 feet (115.6 m)
Discovered: 2006
Estimated Age: 600–800 years

Hyperion’s location is kept secret, and it is now officially off-limits to visitors due to the heavy ecological impact of tourism. The tree’s shallow root system and its fragile ecosystem mean excessive foot traffic can permanently damage both the tree and its neighbors. Despite the hype, Hyperion’s trunk is smaller than other massive redwoods, and tourists are urged to enjoy the majesty of redwoods visible from established trails.

Other Remarkable Giants: Notable Largest Trees Worldwide

General Noble Tree: Once the largest cut tree, the General Noble Sequoia was felled in 1892 for the 1893 World’s Columbian Exhibition. It stood 285 feet (86.9 meters) tall, with a base diameter of 26 feet (7.9 meters) and an estimated volume of 1,250 m³.
Raven’s Tower: An exceptional redwood, believed to reach over 320 feet (97.5 meters) in Prairie Creek Redwoods State Park.

Other giants include the Centurion (Australia’s tallest eucalyptus) and various notable trees in the Andes, Africa, and Asia, but California’s sequoias and redwoods remain unrivaled in terms of collective size and age.

Why Do These Trees Get So Big?

Giant trees grow where conditions allow uninterrupted centuries of development. Key factors include:

Climate: Mild temperatures, reliable precipitation, and protected groves facilitate growth.
Soil: Deep, well-drained soils deliver nutrients and water.
Fire Cycles: Periodic wildfires clear the understory and maintain healthy ecosystems.
Human Protection: National parks and reserves shield these ancient forests from logging and development.

Threats Facing the World’s Biggest Trees

Despite their resilience, giant trees face growing threats:

Wildfire: Recent severe fires have damaged or destroyed significant sequoia groves.
Drought: Extreme droughts threaten their ability to draw water from the ground and the atmosphere.
Bark Beetles: Infestations can kill stressed trees weakened by climate change.
Tourism: Off-trail visitors can compact soil, trample roots, and disturb fragile forest ecosystems—leading to restricted access, as with Hyperion.

Conservation efforts and research are now essential for preserving what remains of these ancient giants. Scientists actively study their sensitivity to changing climate, drought, and human impacts to develop strategies for protection.

How Are Giant Trees Measured?

Tree measurement is a rigorous process, combining traditional field methods and modern technology:

Height: Measured with laser rangefinders, drones, or tape drops from the top branch to the ground.
Volume: Estimated by modeling the trunk’s shape and dimensions; specialized formulas account for taper and irregular growth.
Diameter/Circumference: Measured at a consistent height above ground—often at ‘breast height’ (4.5 feet or 1.37 meters).

Measurement teams often include botanists, climbers, and data scientists, especially when trees reach inaccessible heights or require complex calculations to account for branches.

Giant Trees Through Time: Human Fascination and Impact

For millennia, giant trees have inspired myth and legend, featured in world fairs and exhibitions, and driven scientists to develop new methods of measurement. The largest tree ever felled by humans, the General Noble Tree, was cut for the 1893 World’s Columbian Exhibition, requiring specially built scaffolding and an intensive multi-day operation by a specialized team.

Aside from their immense physical presence, these trees serve as living archives, recording centuries of natural history in their rings. Their survival depends not only on natural conditions, but also on the stewardship and respect of those who interact with their habitat.

Why Are Giant Trees Important?

Carbon Storage: Large old trees store immense amounts of carbon, helping mitigate climate change.
Habitat: They provide unique homes for birds, mammals, insects, and epiphytes.
Water Cycles: Deep roots influence water tables and maintain healthy soil structure.
Cultural Symbolism: Throughout human history, giant trees have symbolized endurance, wisdom, and the interconnectedness of ecosystems.
