Choosing the right hook size for coarse fish
Hook size has a direct effect on presentation, bite detection and how safely a fish can be landed. A hook that is too large may look unnatural, while one that is too small can struggle to hold a powerful fish or carry a generous bait.
For UK coarse fishing, hook sizes commonly range from 2 to 22. The numbering can seem backwards at first: a size 2 is much larger than a size 16, and a size 22 is tiny. The ideal choice depends on the fish, bait, venue and tackle strength.
The advice below is a practical starting point for anglers fishing canals, commercial lakes, rivers and stillwaters. Personal preference matters, but matching the hook to the bait is usually more useful than choosing purely by species.
How hook sizes work
Use the smallest strong hook that presents the bait naturally and remains suitable for the expected fish. A small hook is less intrusive and often improves bites from cautious roach or skimmers, while larger hooks are better for corn, meat, pellets and boilies.
Hook pattern also affects the choice. Fine-wire hooks suit maggots, casters and small worms, whereas wide-gape, forged or carp-style hooks offer extra strength for hard-fighting fish. Barbless hooks are common on many commercial fisheries, but always follow the fishery rules.
A size 18 may be ideal for two maggots, yet entirely unsuitable for a large cube of luncheon meat. Think about hook gape, wire diameter and point exposure as well as the number stamped on the packet.
Hooks for roach, rudd and dace
Roach, rudd and dace are often caught on delicate float tackle with maggots, casters, bread punch or small pieces of worm. Sizes 16 to 22 cover most situations, with size 18 a reliable starting point for one or two maggots.
Drop to a size 20 or 22 when fish are small, the water is clear or bites are shy. Move up to a size 14 or 16 for bread flake, a large bunch of maggots or bigger river fish. Keep the hook point clear and avoid burying it deeply in a bulky bait.
Hook choice for skimmers and bream
Small skimmers commonly fall to size 16 or 18 hooks when fishing with maggots, casters or a single grain of sweetcorn. A size 14 is useful for larger skimmers, especially when using double corn, worm or a sizeable piece of bread.
For big bream caught on feeder tactics, sizes 10 to 14 are often appropriate. The larger hook helps support several maggots, a worm cocktail or two grains of corn without making the bait look untidy.
| Fish or target | Typical hook size | Common baits |
|---|---|---|
| Roach and dace | 18–22 | Maggot, caster, bread punch |
| Rudd | 16–20 | Maggot, bread, sweetcorn |
| Skimmer bream | 14–18 | Maggot, caster, corn |
| Large bream | 10–14 | Worm, corn, pellets |
| Tench | 10–14 | Corn, worm, soft pellet |
| Carp | 6–12 | Pellet, corn, boilie, meat |
| Barbel | 6–12 | Meat, pellet, boilie, worm |
| Perch | 8–14 | Worm, maggot, small live bait where legal |
Sizes for tench and carp
Tench have thick lips and often feed confidently on corn, red maggots, worms and soft pellets. Sizes 10 to 14 are suitable for most tench fishing, with size 12 a versatile option for a single or double grain of corn.
Carp require a stronger pattern because even modest fish can produce powerful runs. Size 8 to 12 hooks suit sweetcorn, luncheon meat, pellets and small boilies. For larger boilies or hair-rigged baits, choose a carp hook with a wide gape and enough strength for the water.
A useful coarse fishing resource can help beginners compare hook patterns, rigs and bait presentation before buying a selection for different venues.
River hooks for barbel and chub
Barbel fishing demands dependable hooks because strong currents and powerful runs place heavy pressure on the terminal tackle. Sizes 6 to 10 are common for meat, pellets, boilies and large bunches of worms. Use a robust, chemically sharpened pattern rather than a fine-wire match hook.
Chub are aggressive but can become wary in clear rivers. Size 8 to 14 hooks cover most chub baits, with size 10 or 12 working well for bread, meat, cheese paste and several maggots. In snaggy swims, use a strong hook and suitable breaking strain rather than dropping hook size too far.
Perch and other predators
Perch have surprisingly large mouths and can take substantial baits. A size 8 to 12 hook suits lobworms, while sizes 12 to 16 are useful for maggots, prawns or small worm sections. Choose a pattern with a strong point because perch can shake a light hook during the fight.
When fishing deadbaits or livebaits where permitted, predator-hook requirements and fishery rules become especially important. Pike have sharp teeth, so a suitable trace and purpose-made treble or single hook arrangement is essential; ordinary coarse hooks are not a safe substitute.
Practical hook-selection habits
- Match the hook gape to the bait, leaving the point and barb area exposed.
- Start with a medium size, then change smaller for shy bites or larger for bulky bait.
- Carry several patterns in sizes 10, 12, 14, 16, 18 and 20.
- Check the point regularly after casting near gravel, weed or snags.
- Follow local rules on barbless hooks, bait restrictions and rigs.
Spend a few minutes preparing a range of hook sizes before your next session, then record which bait and pattern produced the best bites. That simple habit will make your tackle choices more confident and precise across different coarse fish venues.
