The Canadian Shark Research Center reports that the largest accurately measured great white shark on record was a 20.3-foot-long female caught off Prince Edward Island in 1983. A great white shark said to have measured 21 feet was caught off Cuba in 1945, but this measurement has been disputed.
Adult great white sharks normally measure between 13 and 16 feet in length and weigh from 1,500 to 2,340 pounds. The highest weight recognized by the International Game Fish Association was 2,663 pounds; specimens with higher weight have been verified but were disqualified for IGFA entry due to rules violations. Females are slightly larger than males. The only other sharks approaching the great white shark in length are the tiger shark, the Greenland shark and the Pacific sleeper shark, but these sharks are lighter in weight.
