I was wondering if anyone knows the formula for calculating a walleye weight? Length and Girth? I found quite a few calculators online but most of them are WAY off. Walleye Central has one that’s pretty accurate, but I’d like to know the formula. Any one have any suggestions?

Walleye Weight Formula?

Multiply length times girth squared. Then divide by 800 to get weight in lbs. Has worked well compared when compared to my Rapala digital scale.

25 inch = 5 lbs
26 inch = 6 lbs
27 inch = 7 lbs
28 inch = 8 lbs
29 inch = 9 lbs
30 inch = 10 lbs-J.

May 13, 2010 at 10:03 pm #871856Thanks guys, Jon your scale is what I normally go by but if you get one that’s either skinny or super girthy it’d be nice to know roughly what it weighed. I caught a 31″ x 18″ on the Rainy River that went 13.0 lbs even. Based off of my calculations the formula Don Miller posted (Girth X Girth X Length divided by 800) came very close. I don’t weigh a lot of fish so I don’t have any other examples to test out this formula.
If any one catches a big walleye give this formula a try I’d love to hear how close it is. Thanks for the help guys.
guys.
