Print the sizes near your finger size & try them out!
Each ring is designed as simply as possible. (A sliced sphere with a cylinder removed.)
Ring size is cut into inner face in 4mm Arial Black.
Each ring should be ~1.5mm thick.

I created these files and printed several rings so that I could wear a ring for longer than the few minutes one usually has in a store and confirm my ring size.
