Convert the Length of Pike or Walleye to Pounds
We have seen a bunch of charts that convert walleye or pike from their length to their weight. They are all pretty similar, but of course a fish can also vary by the girth of the body so a 36 inch pike might be a couple more or a couple less pounds. These lengths and weights in the conversion chart below are based on averages that we have found. For example, the Saskatchewan Department of the Environment encourages the use of “weigh your fish with a ruler”. It’s quicker and easier on a fish to just measure it rather than the extra handling and extra time out of water it takes to hook on a scale.
For an even quicker method of getting your fish length, Use Your Rod as a Ruler. Just lay your rod down beside the fish and note the tape mark. Ya, you might be off by a half an inch or so but it’s easy and a good estimate.

More Fish Weight by Length
We plan to add some more average fish weights per inch charts here soon. We are busy gathering up the data and putting together the charts for Lake Trout and Rainbow Trout.
