Line & hook calculator

Drag is the setting most anglers guess at. These figures come from the standard practice of setting drag to roughly a quarter to a third of your line's real, knotted strength.

Inputs

Your line

A well-tied, wetted knot in good line typically retains most of its rated strength; a rushed or dry-tightened knot retains much less. Lower the percentage if you are unsure of your knot.

What that means

Line strength in metric
5.4 kg
Effective strength at the knot
10.8 lb
Suggested drag setting
2.7–3.6 lb of pull
Typical leader strength
around 18 lb
Shock leader for heavy casting
around 36 lb
How to actually set it
Clip a spring scale to your line, or have someone pull line off the reel by hand with the rod bent as it would be when fighting a fish. Adjust until line slips at the figure above. Drag set by feel alone is usually far too tight.
Guide

Hook size for the bait

Match hook gape to bait size, not to fish size alone
BaitTypical hook sizeNote
Single maggot or pinkie18–20Fine wire so the bait stays lively
Double maggot or caster16–14Standard match sizes
Sweetcorn or small pellet14–12Point must stay clear of the bait
Worm (whole lobworm)8–4Long shank helps present the worm
15–20 mm boilie8–4Wide gape, mounted on a hair
Small deadbait4–2/0Often two trebles on a wire trace
4 in soft plastic2/0–3/0Offset worm hook, rigged weedless
6–8 in soft plastic4/0–5/0Heavier wire for bigger fish

The rule behind the table: the hook point must never be masked by the bait. If the bait covers the gape, go up a size or mount the bait on a hair.
