Complete Fishing Hook Guide: With Hook Size Chart

Ever had a fish nibble at your bait and take off before you could set the hook? Or maybe you’ve hooked into a solid fish, only to watch your hook pop free just before landing it? More often than not, it comes down to using the wrong hook size.

Fishing hooks aren’t one-size-fits-all. The right hook size depends on your target species, bait, and even the fish’s mouth size. Go too small, and a big fish might shake it off. Go too big, and small trout or other small fish won’t even take the bait. Whether you're rigging a circle hook for live bait fishing, tying a J-hook for bass, or using treble hooks for aggressive predators, knowing the right hook type makes all the difference.

In this guide, we’ll break down different hook sizes, cover saltwater fishing hook sizes, and help you pick the right hook for the job. By the end, you’ll know exactly what to reach for in your tackle box - no guesswork, no lost fish.

Hook Size Guide: How to Pick the Right Hook

How Hook Sizes Work: Understanding Numbers & Measurements

If you’ve ever looked at a fishing hook size chart and felt like it was written in a secret code, you’re not alone. The numbering system for hook sizes can be confusing at first, but once you get the basics, it’s easy to figure out the right hook size for your target species.

Here’s the deal:

• Smaller hook sizes have larger numbers (e.g., a #10 hook is smaller than a #2 hook).

• Larger hook sizes use aught sizes, marked as “/0” (e.g., a 2/0 is bigger than a 1/0). The bigger the first number, the larger the hook size.

The size you need depends on the fish species, bait, and fishing technique. For example:

• A smaller hook size (like a #12) is great for small trout and panfish.

• A medium hook (like a 1/0) is solid for bass and medium fish.

• A larger hook (like a 5/0 or bigger) is what you’ll want for large fish like giant trevally or marlin.

Fishing Hook Size Chart: Freshwater & Saltwater Guide

When it comes to picking the right hook size, there’s no universal rule - it all depends on what you’re fishing for. A size hook that’s perfect for small trout won’t cut it for a big fish like a tarpon. Below is a fishing hook size chart to help you match the hook size to your target species.

Freshwater Hook Size Chart: Best Hooks for Common Species

Freshwater hook sizes range from tiny #32 hooks for delicate fly fishing presentations to massive 27/0 hooks used for catching huge catfish. Here’s a general guide:

Saltwater Hook Size Chart: Best Hooks for Bigger Fish

Saltwater fishing hook sizes tend to run larger than their freshwater counterparts because saltwater fish are generally bigger and stronger. From catching snook on the flats to battling giant trevally offshore, your hook size depends on the target species and the type of fishing you’re doing.

Fishing Hook Types: Choosing the Right Hook for the Job

Picking the right hook type is just as important as choosing the right hook size. Different hooks are designed for different fishing styles, baits, and fish species. Below, we’ll break down some of the most common hook sizes and types so you know exactly which one to grab from your tackle box.

Circle Hooks: Best for Live Bait & Catch-and-Release

A circle hook is a game-changer for live bait fishing. Unlike a traditional J-hook, it’s designed to slide into the fish’s mouth and hook the corner instead of the hook being swallowed, making it great for catch-and-release fishing.

• Best for: Saltwater and freshwater live bait fishing

• Target species: Redfish, tarpon, tuna, catfish

• Why use it? Less gut-hooking, higher survival rate for released fish

J-Hooks: Versatile Hooks for All Fishing Styles

The J-hook is the classic workhorse of fishing hooks, shaped just like the letter "J." Whether you’re using smaller hooks for small fish or larger hooks for big fish, J-hooks work well with both live bait and artificial lures.

• Best for: Almost any fishing style

• Target species: Bass, walleye, trout, snapper

• Why use it? Great hook-up rate, easy to set

Treble Hooks: Best for Lures & Hard Baits

A treble hook has three hook points, increasing your chances of hooking a fish when using hard baits. It’s the go-to for crankbaits, spoons, and topwater plugs.

• Best for: Artificial lures and hard baits

• Target species: Pike, muskie, bass, striped bass

• Why use it? Multiple hook points mean better hook-ups

Long Shank Hooks: Preventing Line Cuts from Toothy Fish

A longer shank helps prevent sharp-toothed fish from biting through your fishing line - which is why experienced anglers love them for species like bluefish and mackerel.

• Best for: Saltwater fishing, toothy fish

• Target species: Mackerel, bluefish, barracuda

• Why use it? Keeps fish from cutting the fishing line

Short Shank Hooks: Stronger for Heavy-Fighting Fish

A short shank hook is compact and strong, making it ideal for fish that fight hard and twist a lot, like grouper and snapper.

• Best for: Heavy, aggressive fish

• Target species: Grouper, snapper, drum

• Why use it? Less chance of the hook bending under pressure

Hook Care & Safety: Keep Your Hooks Sharp & Rust-Free

Fishing success doesn’t just depend on picking the right hook size, it also depends on keeping your fishing hooks sharp and in good shape. A dull or damaged hook point can cost you fish, and a rusted-out hook can snap at the worst moment. Let’s break down how to keep your hooks sharp and when to get rid of them.

How to Keep Hooks Sharp: Best Sharpening Techniques

Even the best hook types lose their edge after a few uses, especially when fishing in rocky areas or battling large fish with tough mouths. Here’s how to keep them razor-sharp:

• Use a hook file or whetstone – Always sharpen in one direction (not back and forth) along the hook point.

• Focus on the tip – A few light strokes at the sharp end will restore its piercing power.

• Check for resistance – Run the hook point over your thumbnail - if it doesn’t scratch, it needs more sharpening.

Pro Tip: Saltwater anglers should rinse their saltwater fishing hooks after every trip. A quick freshwater rinse prevents rust buildup, extending the life of your hooks.

How to Dispose of Old Fishing Hooks Safely

Got a hook that’s bent, rusted, or snapped? Tossing it in the trash can be dangerous. Here’s how to safely get rid of old hooks:

• Snip off the sharp end – Use wire cutters to remove the point and prevent injuries.

• Secure in a container – Place old hooks in a sealed container or an old tackle box before disposal.

• Check local regulations – Some areas have recycling programs for old fishing gear, always good to check.

• Buy fish hooks that dissolve

Final Thoughts: Catch More Fish with the Right Hook

Choosing the right hook size and hook type is what separates a great day of fishing from a frustrating one. But let’s be honest, sometimes you just want to hit the water without overthinking gear, bait, or whether you’ve got the right hook size for your target species.
