Estimating the weight of my catches?

General Fishing Questions

I dont have a fishing scale, and I’ve often found myself with a great catch in hand, but no idea how much it weighs.

Is there any way to estimate the weight of your catch?

How do you weigh your fish? Do you all carry a scale with you at all times?

    I carry a small measuring tape, and measure all my catches.
    Then I use this simple little formula: length x girth x girth รท 800
    (Remember to measure in inches)
    This will give you a great approximation of what the fish weighs.

    Oh – and if you ever leave your measuring tape at home, then here’s another little trick: just use a small piece of fishing line to measure the fish (trim the line to the size of the fish, then measure the line when you get home!)

    Works great for most fish:
    length x girth x girth / 800

    This is specifically for fat-bodied fish like bass and salmon. For thinner fish like trout then divide by 900.

    I’ve got a really small digital scale that I got as a gift (so I’m not sure how much it cost). It’s great, but can’t weigh much. I always snap a pic of my good catches so I can show them off instead of telling people how much they weigh.
