Small: US Ring Size 3-6 with a Large Stone

Medium: US Ring Size 6.5-11 with a Large Stone

XL: US Ring Size 11.5+ With a Large Stone

If your stone is raised, or particularly large, this may prevent a perfect seal and cushion with your RingGuard.

However our custom-blended flexible and cushioning silicone will still provide protection.

A Smaller Size will provide a tighter fit, but less cushioning, however, a Larger Size may feel loose.

If you are looking to secure your ring, a tight fit is more important that cushioning.

Small: US Ring Size 3-8.5

Medium: US Ring Size 9-12.5

XL: US Ring Size 12.5 & Above

A Smaller Size will provide a tighter fit, but little cushioning, however, a Larger Size may feel loose.

If you are looking to secure your ring, a tighter fit is more important that cushioning.

We recommend Medium Size for Oura Smart Rings up to US Size 12.5
