The weight of the largest known great white shark ever recorded in history is at least 2,730 pounds. However, there may be a possibility of an even bigger great white that can weigh as much as 5,070 pounds but it is yet to be confirmed. In 1986, a female white shark was caught off Pt. Vincente in California. It had a weight of around 4,140 pounds.
The average weight of a male white shark ranges from 1,150 to 1,700 pounds while the female great whites are heavier and weigh around 1,500 to 2,450 pounds.
