What is My Silicone Ring Size?
Take 2 minutes to find your silicone ring size!
A great fit means all-day comfort — snug enough to stay in place, but with just the right breathing room. Use any of the methods below to find your ideal size.
✅ Note: Silicone rings often fit 0.5 to 1 size smaller than metal rings. They flex, contour to your finger, and stretch over your knuckles — so don’t be surprised if your perfect fit is a little different from your metal band.
For example: If you’re between sizes, such as 9.5, we recommend sizing down to a 9. If you are a size 9, stick to size 9.

If you’re gifting a ring or don’t have tools handy:
- Compare with a similar person's hand size.
- Guess conservatively — silicone rings are flexible, so being slightly snug is usually okay.
