The Observatory said it managed to document the death of 321,358 people, and that among the killed civilians were 17,400 children and 11,000 women.
The toll also included 114,474 government forces and allied fighters.
On the other side, the casualty tally included 55,000 rebels and Kurdish fighters, said the London-based Observatory.
