The hook charts I looked at are good for referencing shape, but I did not see where they state anything about size differences. I made a thread a while back where I got the exact same shape I had been buying in Mustad hooks, in a Daiichi hook. I used 1/0 in Mustad and got the 1/0 in the Daiichi. Here's what I got.
I had to go up to a 5/0 in the Daiichi to get the same size as the Mustad 1/0.
