How to Calculate a Fish’s Weight Without a Scale

To determine a fish’s weight based on its length and girth, use the form above. Leave it blank if you are unsure of the fish’s girth, and it will be calculated for you.

Before releasing a fish, take a few quick measurements of it, and use the form to calculate its approximate weight.

The following fishing equation will yield an estimate that is within 10% of the actual weight, while no formula can ever fully replace an exact scale.

Hey there, my name is Sean – OnTrack Fishing is my site. I’m based in the UK yet I’ve been fortunate enough to catch bass in the States, barramundi in Australia, trout here at home and carp on the Danube delta. If I’m not fishing, or talking about fishing, then….I’m probably asleep.
