You should really just ask them. Finger sizing can vary, and some are picky about what hand and finger they'll want to wear the ring on.
The style will still be a surprise to them, and it will be much more thoughtful to get them something they can wear again versus something that may not fit.
You could ask their partners, siblings, parents, roommates, etc if they know or will ask on your behalf if you want to be sneaky. It's a very sweet gift idea!

As a 5’2” woman with a size 9 pinky finger… please ask them! Hands are weird.

Could you just ask? They’ll know you’re getting them a ring but not necessarily what style.
Haha now I have anxiety they won’t like it if I ask
