Hook size by fish
Recommended size

⚠️ Hook sizing differs by system — freshwater hooks get bigger as the gauge rises, while sea hooks (#) get smaller as the number rises. Even at the same number, actual size differs by maker and hook type, so the table is a general reference.
Reference (fish ↔ size)

⚠️ This calculator is a reference tool based on the standard line/sinker specifications (gauge-to-diameter) established in Japan and also used in Korea, plus publicly available conversion data. Real products vary in diameter, strength (lb) and weight for the same gauge depending on material (nylon, fluorocarbon, PE braid), maker, number of braided strands (4/8) and coating, so results may differ from the product label. PE braid lb ratings in particular vary widely by maker, so treat them as a range and always check the product label for exact values. calcstool.com assumes no liability for tackle choices, equipment damage, accidents or fishing outcomes based on these results.
FAQ
Does a bigger number mean a bigger hook?
It depends on the system. Freshwater hooks get bigger as the gauge rises, while some sea hooks (#) get smaller as the number rises.
What size for crucian carp?
Roughly #2-5 (small), #6-9 (mid), #10-13 (large), varying by maker and hook type.
Same number = same size?
No. The same number differs in real size across hook types and makers, so the chart is a reference.
