Hook sizing is the most confusing numbering system in fishing: for freshwater sizes the number gets smaller as the hook grows, and then around 1/0 the direction flips.
| Size | Roughly | Typical use |
|---|---|---|
| 12 – 8 | Very small | Trout, panfish, ice fishing with tiny baits |
| 6 – 4 | Small | Panfish, drop shot, small worms and live bait |
| 2 – 1 | Medium | Finesse bass, walleye, light live bait |
| 1/0 – 2/0 | Medium-heavy | Bass Texas rigs, standard worm hooks, small swimbaits |
| 3/0 – 5/0 | Heavy | Big worms, creature baits, pike, heavier swimbaits |
| 6/0 + | Extra heavy | Muskie, saltwater, large swimbaits and live bait |
Hook lengths differ between manufacturers and between thin-wire and heavy-wire versions. Compare the gap and the wire gauge, not just the number. Use our Hook Size Selector for species-specific sizing.
| Style | What it does | Use it for |
|---|---|---|
| Offset / EWG worm hook | Wide gap, offset bend so a soft plastic sits straight | Texas rigs, creature baits, weightless plastics |
| Circle hook | Rolls into the corner of the mouth by itself | Live and cut bait, catch-and-release fisheries, saltwater |
| Octopus / beak hook | Short shank, turned-in point | Salmon, steelhead, bait under a float |
| Baitholder hook | Barbs on the shank to grip bait | Nightcrawlers, minnows, leeches |
| Treble hook | Three points on one shank | Replacing hooks on hard baits, topwater |
Three styles in three sizes will handle nearly every freshwater situation you will meet. Buy them in 25-packs, not singles.
The workhorse for soft plastics. 3/0 fits a 5–6 in stickbait or creature bait; 2/0 for finesse worms. Look for a wide gap and a straight-shanked point.

Check current price on Amazon →Short-shanked and strong, ideal for float fishing and for bait that needs to sit naturally. Also a good general-purpose hook when a worm hook is too aggressive.

Wire gauge. A thin-wire hook penetrates easily and is right for finesse presentations; a heavy-wire hook survives big fish and heavy cover but needs more hook-set force. Match the wire to your line and cover, not to the fish's size.
Gap width. The gap must clear the plastic. If your bait is thick, move up a hook size rather than bending the hook out — a bent hook loses strength right where you need it.
Cross-check your selection with the Hook Size Selector and the Jig Head Weight Guide when you are rigging plastics on a head instead of a hook.
The numbering is only half of what a hook spec tells you. The hook size chart puts every size side by side, the hook size selector narrows it to your bait, and the species size chart shows the fish each size targets.
Yes. Once the numbering crosses into the ought sizes the number grows with the hook, so 1/0 is the next step up from a size 1, and 3/0 is larger still.
A 3/0 is the standard answer for a 5–6 in stickbait or creature bait, 2/0 for finesse worms, and 4/0–5/0 for big swimbaits and punching. The gap should clear the plastic body with a little room to spare.
They can, but they are designed for bait where the fish turns away and the hook rotates into the corner of the mouth. With plastics, the hook-set motion is what prevents a circle hook from working as intended — use an offset worm hook instead.
