Is this a correct way to measure fist size in boxing?

Thanks. What would you guess mine is in inches? I'm math illiterate but it could be good to know.. I know the famous fighters inches.

Nope

Your way is the correct way the other way your measuring finger length

But that way I got 8 inches, and that can't be right. I'm 6'1 (186 cm) tall.

My breadth was above average but my fist size is below average?

You must have small knuckles I’m 5’7 and that way I have 11 inches but my knuckles are large

Yeah there is some imbalance.

It looks small closed fist front view, but relatively large from the side.

This does not look like 8 inches to me from the side.

Looks like 9.5 but put it on your knuckles and it will be greater

But isn't thickness more crucial than measurements? You don't get any weight from mere measurements.

Rocky Marciano had small but thick fists...
