Fishing Hook Sizes Guide Explained to my 10-year-old boy
We were out for giant Groupers in the mediterranean sea. I wanted to check if they would chase a new Multi Jointed Swimbait I got on Amazon, and my son stuck to his junior spinning rod with some dead shrimps as bait.
While I didn’t get any action, my boy did, and after two small sea brims that were released un-harmed, he hooked a strong grouper that, sadly, when it was 3ft from where we stand, he managed to get away while snapping my son’s hook 🙁
Imagine the look he gave me when he rolled in the line to discover his #6 Gamakatsu Octopus Circle Hook cut in half.
So he rained on me a slew of queries about fish hook sizes, what size he should have utilized for this grouper, and I found myself rummaging through my brain to guide him through the expertise while attempting to keep it as basic (and interesting enough not to lose his 2022 children’s attention).
First thing first: What is a fishing hook size?
A fishing hook size is simply the measurement of the gap between a fishing hook’s point and shank.
The shank, point, barb, and eye are the four components of a fishing hook. A fishing hook’s shank is the long, straight section. It extends from the gap (the cut-out region between the point and shank) to near where it meets with the eye at its end. The size of your bait can.
The point is the most critical component of a fishing hook, as it allows your hook to pierce an animal’s mouth when you’re attempting to catch fish. It’s also what makes or determines whether it’ll be simple for an angler to pull their caught fish from the water. A decent fishing hook point should be sharp, thin, and robust.
The barb is a small projection on the bottom of the shank that keeps your bait from being removed by any predator once it’s been hooked. The thicker its diameter, the better your catch will be protected during a fierce struggle with a fish or another predator.
A fishing hook’s eye is the end of the line or lure that connects to it, and it’s typically composed of stainless steel. The manner in which an angler ties their knots also affects how well a fishing hook holds on firmly throughout your entire outdoor excursion.
What are the most common fishing hook sizes?
Fishing hooks sizes range from tiny #32 and up to giant 20/0.
In between the scale goes from #32 to #1 and then keeps growing from 1/0 to 20/0.
To get an idea of the actual size, a #6 hook gap is 9mm in width, while a 2/0 hook gap is 17mm. we have a full Fishing Hook Size Chart you can learn more about and find your preferred hook size.
The most common freshwater fishing hook sizes are from #20 for flies to a big 10/0 for catfish, while for saltwater and boat fishing they get larger to handle sea monsters.
At this point, my son showed his brilliant mind (forgive me for this :), and asked me “What hook size should I use if there are different species and sizes?”
Of course, I was proud of him because his question shows a good grasp of the situation. As for the answer, my short version was: Pick the smallest hook size you can get away with (I got A menacing look to remind me of the grouper who got away…)
The longer answer is that you have another option – If you want to hook a big fish and decrease the chance of losing him to wick-hook (or line, or rod), go bigger and know that you’ll miss all small-medium fishes in your spot.
He accepted my longer explanation and asked:
So what hook should I use for the grouper that got away? (Or largemouth bass, or catfish, etc.)
Many newbie anglers ask this question in similar words; the most common is “How do you know what size fishing hook to use?“
As for my son and his specific case, I said, “I’m guessing the grouper was a 10lb (4.5kg) grouper, so a size 2/0 should be sufficient. But a size 2/0 hook would not help you because your junior rod would have snapped under its weight”.
For all anglers asking this general question, generally speaking, you should use the smallest-sized fishing hook that will still fit the bait. utilizing a hook too large for the appeal will often result in missed fish.
As you can probably understand, we’re entering a wider world of baits and the species they are fit to.
Here are a few examples:
- A small fishing hook (#6 – #2) is excellent for use with live bait, like minnows, that would work perfectly for walleye and trout.
- For larger baits, like cut bait or chunks of fish, you’ll want to use a medium or large fishing hook (2/0 – 5/0) that would work well with salmon and gar.
- If you’re using artificial lures, experiment until you find the best size for the lure and fishing conditions. Fishing hooks can be as small as a #16 hook for fishing tiny lures or as large as a #4 hook for fishing more extensive, heavier baits.
