 How Much Does That Fish Weigh?

Fish Weight Calculator

Use our very own My Bait Shop fish weight calculator to find out.  Our calculator currently supports Bass (Largemouth and Smallmouth), Musky (or Muskie) and Northern Pike.  Just enter the length and girth and our formula takes care of the rest.  Keep in mind this is only an estimate and fish can vary greatly from fish to fish and region to region but have some fun with it.



Formula is exclusive My Bait Shop formula. Derived by looking at dozens of calculators, formulas and data points available and adjusting to what I thought produced the best results for the most common ranges while still maintaining a simplistic weight calculator. One such source I found to be excellent was the WI DNR Trophy Converter.  I will continue to adjust the weight formula going forward as I find ways to improve both the algorithm and data points.
