    Once the
    Ring app has been downloaded set the settings to US Sizes.  Place a ring you may have on the screen and
    use the slider to match the INSIDE of the ring.The best
    fingers to use for LYF Ring will be the Pointer, Middle and Ring fingers, so
    when sizing your ring size take this into account.

    If you are not confident with the Ring App we can send you a Complimentary Sizing kit. All you need to do is select a Kit and this will be sent as a part of your order and prior to the ring being sent.

    Choose Sizing Kit

Wearing Guide

01

Choose The Right Finger

  • Use your non-dominant hand for better consistency and comfort
02

Ensure a Snug, Comfortable Fit

  • Ring should fit securely but not tightly
  • It should slide over your knuckle with a gentle twist
