Looking at the chart, we can see two sections:
Top section:
It says “As the # number gets larger hooks get smaller.”
The numbers go from 1 to 20. Hook #1 is the largest in this group, and hook #20 is the smallest.
Bottom section:
It says “As aught or ought gets larger hooks get larger.”
The numbers are written as 1/0, 2/0, up to 9/0. Here, 9/0 is the largest hook shown, and 1/0 is the smallest in this group.
The note at the bottom says:
“The smallest commercially available hook size is a #32 and the largest is an aught 27/0.”
So, if we’re being asked which hook is the largest overall — based on the chart and the note — it’s clear that the “aught” sizes (like 9/0, 10/0, etc.) get bigger as the number increases, and the biggest one mentioned is 27/0.
Therefore, the largest commercially available hook size is 27/0.
Final Answer:
27/0
