What Fishing Hook Sizes Are There?

Hooks come in many different sizes according to their usage, saltwater and predator hooks are usually the largest and range typically in fly fishing from 5/0 down to 1/0 (aught sizes) then 1 down to size 10. Freshwater flies typically range from size 4 down to size 32!

	As these size charts show Hooks start in Augt or /0 sizes with a 5/0 larger than a 3/0, the larger the number in front of the slash "/" then the larger the hook. From size 1/0 hook sizes go from 1 and increase in number so a size 10 hook is much larger than a size 20 hook and a size 32 hook is smallest of them all, and yes fly fishermen tie flies as small as size 32.
