What was the average size of a Woolly Mammoth?

Woolly mammoths were about 9 to 12 feet tall. That isn't noticeably taller than Asiatic elephants, but the woolly mammoths did weigh more (up to 8 tons). There was also a dwarf variety of woolly mammoth that lived on Wrangel Island. They measured 6 to 7.5 feet tall.
