Walleye Weight Formula
The formula to calculate the weight for a Walleye that is 20 inches long and has a girth of 12 inches is as follows. Walleye have a shape factor of 750.
WEIGHT = LENGTH x GIRTH² / SHAPE FACTOR
WEIGHT= 20 x (12²) / 750
WEIGHT= 20 x 144 / 750
WEIGHT= 2880 / 750
WEIGHT = 3.84 pounds (This would be a very fat Walleye)
