The factory bodies use size 1 I usually build them with 1/0
My bad...thinking backward.
Size Matters. How It’s Measured In Fish Hooks.
Fishing hook sizes follow a strange numbering convention that is actually quite simple once you understand it. Basically, the numbering system divides the small and large hooks. In theory, size “0” would be in the middle – but I’ve never seen a hook designated as Size “0”.
Hooks that are smaller than the nominal size 0 are given a number. The higher the number, the smaller the actual hook. So a size 6 hook is 4 sizes smaller than a size 2….. and they go down to around size 32. Make sense?
At the other end of the scale, hooks that are bigger than “Size 0” get given a “/0” label…… and the higher the number the larger the hook. So 4/0 is two sizes bigger than 2/0. And they go right up to 20/0.
Once you get the hang of it, the sizing convention makes perfect sense – except for one thing. There’s no agreed standard between manufacturers. So a size 2 hook in one brand could be significantly bigger or smaller than the same size in a different brand.re: Greg Vinall
