Hook sizes
What size hook for bass
For most bass fishing, 2/0 to 4/0 covers it. Soft plastics take a 3/0 or 4/0 offset worm or EWG hook, finesse plastics and drop shot take 1/0 to 2/0, and live bait takes a 2/0 to 4/0 J or circle hook. Crankbaits and jerkbaits keep the #4 to #2 trebles they came with.
Hook size by bait
Every row comes from the same recommendation engine that powers the Hook Size Finder, so the tool and this table always agree.

Scroll the table sideways to see every column.
Sizes are ranges because hook numbering is not standardized. Two hooks stamped the same size in different styles or from different brands can differ noticeably in gap.
The hook styles in that table
Octopus hook
Short shank, round bend and an up-turned eye for snelling. Compact and light for its gap.
Sizing: Short shanks make an octopus hook look smaller than a J hook of the same number even though the gap is comparable.
Watch out: The light wire that makes them good for live bait will open up on heavy drag or big fish.
J hook
The general-purpose bait hook shape most people picture when they think of a fish hook. Straight or slightly offset point, moderate shank.
Sizing: Printed sizes are consistent within a model family but not across brands. Compare gap width, not the number.
Watch out: Because the point faces the shank, a J hook set late tends to catch deep. If you are fishing bait on a rod holder, a circle hook is the better tool.
Circle hook
Point curved back toward the shank so the hook slides to the corner of the jaw and turns as the fish swims away.
Sizing: Circle hooks run visibly smaller than a J hook of the same printed size, so most anglers step up one or two sizes when switching.
Watch out: Do not set the hook. Let the rod load and reel steadily. A hard swing pulls the hook out of the fish's mouth.
Offset worm hook
A Z-bend in the shank holds the nose of a soft plastic in place so the bait stays straight and the point can be buried weedless.
Sizing: Sized to the bait, not to the fish. Match the gap to the thickness of the plastic in the hook's bend.
Watch out: Too small a gap on a thick bait is the most common cause of missed hooksets on Texas rigs.
Jig hook (leadhead)
A hook moulded into a weighted head. Hook size and head weight are chosen separately.
Sizing: Package weight in ounces tells you sink rate, not hook size. A 1/16 oz crappie head and a 1/2 oz bass jig can carry very different hooks.
Watch out: Pick the head weight for the depth and current you are actually fishing, then check that the hook matches the bait.
Treble hook
Three points on a common shank, used as factory hardware on crankbaits, jerkbaits, topwater and spoons.
Sizing: Treble sizing runs on the same printed ladder but the practical range is much smaller. Most freshwater hard baits carry #8 to #2, with 1/0 to 4/0 on larger saltwater plugs.
Watch out: Changing treble size changes how a lure runs. Going up a size can kill the action of a small crankbait or sink a topwater.
Why these sizes for bass
Bass tackle is the reference point most gear is built around, so recommendations here have the least uncertainty of any species on the site.
Ambush feeders that position against cover or a current break and take a bait moving past them. They inhale rather than bite, which is why bite detection matters more than hookset strength on most presentations.
Common mistakes
Undersized hook gap on Texas rigs
A 2/0 worm hook buried in a thick creature bait often does not have enough clearance to reach the fish's jaw. If you are getting bites and not hooking up, go up a size or to an EWG.
Braid straight to the bait in clear water
Braid is highly visible. On clear reservoirs and smallmouth water, a fluorocarbon leader is usually worth the extra knot.
A fast rod on a crankbait
A fast action plus treble hooks means fish tear off on head shakes. Crankbaits want a moderate action that lets the fish load the rod.
