What does a perfect fit look like?

  • Too Tight

  • Perfect Fit

  • Too Loose

  • When trying on your ring sizer, aim for a fit that feels secure and comfortable :

    • 1) Your ring should slide smoothly over the knuckle with a gentle push.

    • 2) It should come off with a little resistance — not too tight, not too loose.

    • 3) Try the shake test : relax your hand by your side and give it a gentle shake. The ring should stay in place and not slip off.

    Keep in mind: fingers can swell or shrink slightly throughout the day, so try your sizer at different times to see what feels best overall.
