Fly Fishing Calculator

We’re fly fishing enthusiasts, Gonzo Fly Brothers. And we’ve created this calculator to help fly fishermen find the best line weight for their rod.
There are three types of rods - single handed, switch and double handed.
Using the right line weight will help you load your rod better and have a better fishing experience.

“Line” - fly line weight recommendations for different weight classes of rods
“Load” - min and max recommended line weight for the rod
