4/0 hook
A 4/0 is inside the hook size window for 11 species the Rig Studio models (Speckled Trout, Flounder, Largemouth Bass, Channel Catfish, Northern Pike, Snook, Redfish, Salmon (Coho / King), Striped Bass, King Mackerel and Muskellunge). One stock size smaller is 3/0, one larger is 5/0.

What fish a 4/0 hook is for
Every species whose window includes 4/0, lightest fish first. The wire floor is the studio's other hook check: a hook rated under 1.2× the fish's top typical weight is flagged. The last column lists the tie-on hooks we catalog in 4/0 that clear it.
One or two sizes off: what the studio says
Fish whose window ends just short of 4/0. Put a 4/0 on one of these in the builder and it raises a warning, not an error, with a one-click fix to the nearest edge of the window. A hook a size off still catches fish; it just pins fewer of them.

Hooks we catalog in 4/0
Each pattern whose printed size range includes 4/0. Wire is relative to standard gauge; "holds" is the pull the maker rates it to before the wire opens. The last column counts the fish above that this hook clears both checks for.

Rigs the engine builds on a 4/0 hook
Solved species-and-venue rigs where the solver put a 4/0 on the line. It picks the stock size nearest the middle of the window the hook and fish share, then grades the whole build with the same checks the studio runs.

What fish is a 4/0 hook for?
Speckled Trout, Flounder, Largemouth Bass, Channel Catfish, Northern Pike, Snook, Redfish, Salmon (Coho / King), Striped Bass, King Mackerel and Muskellunge. Those are the species whose working hook window includes 4/0. It is the smallest size we accept for Muskellunge. It is the largest we accept for Speckled Trout. Size the hook to the bait as well as the fish: the window is where a hook clears the jaw without swamping the mouth.
Is a 4/0 hook bigger than a 3/0?
Yes. Aught sizes grow as the number climbs, so 4/0 is larger than 3/0 and smaller than 5/0.
How big is a 4/0 hook in millimetres or inches?
We do not print a figure, because there is no standard one. Hook sizes are not tied to a length or gap measurement, so a 4/0 from one maker can differ visibly from another's, and patterns differ more than makers do: a long-shank Aberdeen and a short octopus of the same printed size are not the same hook. Compare a new pack against a hook you already know.
Which hook pattern should I buy in 4/0?
7 hooks we catalog come in 4/0: Owner Jungle Flippin' Hook (j, rated 95 lb); Mustad Demon Perfect Circle (circle, rated 90 lb); Eagle Claw Lazer Sharp Circle Sea (circle, rated 70 lb); Mustad O'Shaughnessy Siwash (siwash, rated 65 lb); Gamakatsu Superline EWG Worm Hook (ewg, rated 60 lb); Owner Mutu Light Circle (circle, rated 45 lb); Gamakatsu Octopus Hook (octopus, rated 30 lb). Pick by technique: j for flipping and punching heavy cover; circle for bait soaked on a tight line; hooks the jaw hinge without a hookset; siwash for single-hook swap on spoons and spinners for salmon and steelhead; EWG for texas-rigged soft plastics; octopus for live bait, drop-shot, and baits that have to sit naturally.
