According to the plaque:

 

GENERAL SHERMAN TREE

LARGEST LIVING THING ON EARTH

 

The General Sherman Tree stands as the ultimate example of the growth potential of a giant sequoia tree (Sequoiadendron giganteum).  Other types of trees are taller, or thicker at the base, but no other living thing on this planet exceeds the volume of this giant sequoia.  The General Sherman Tree owes its immense size not to great age (many other sequoias are older) but rather to its very rapid growth rate.  For over two thousand years this tree has survived numerous fires, climatic change and even the coming of modern man.  Today it remains not only the world’s largest living thing, but also one of the fastest growing.  Every year it grows enough new wood to make a 60 foot tall tree of usual proportions.

 

Estimated age                                2300 – 2700 Years

Estimated weight of the trunk          1385 Tons

Height above base                          102.6 ft.

Maximum diameter at base              36.5 ft.

Diameter 180 ft. above ground          14.0 ft.

Volume of the trunk                         52,500 cu. ft.

Above is a big tree.  I don't know if it had a name or not but it really gives you a sense of just how big these sequoias are.
