Index? The pointer finger?
avg ring finger in US is 7 or 8, so up I'd say probably 9 or 10, in abouts there....
I don't know exactly what my index finger size is, but I would guess somewhere around a 6, since my ring finger is 5.5 and is slightly smaller than my index.
indexes are 9 1/2, one closer to 9 3/4....ring fingers are 7 and 7 1/2....in my group of midwest, whitebread friends, I'm on the slightly high side of average, but one of them has tiny hands!!
My index finger is a 9, my ring finger is a 5.5! Big difference!!!
Most retailers sell ring size 7 (every ring i've gotten has been a 7 and most had to be resized to fit a different finger)
Used to be the same as shoe size. used to be avg size was 7.5 for shoes, and 7 or 7.5 for ring finger (same as glove size).
My ring finger is a 5 1/2 and my pointer finger is a
6 1/2 or sometimes a 7.
I sell lots of rings if you would like to take a look :)
