Helpful Hints

  • If you are aiming for a surprise, read our tips about how to find your partner’s ring size without her knowing.
  • One tried-and-true method is asking a parent or close friend if they know her finger size.
  • Borrow one of your partner's rings and use the Ring Sizing Guide above to determine its size. The ring should be from the correct finger on the correct hand.
  • Our dominant hands are generally slightly larger – make sure you measure for her left!
  • The average finger size is a 6 to 6.5 for women, and 9 to 10 for men. When no other information is available to you, selecting one of these sizes is your best choice.
  • Rings with wider bands will fit a bit tighter. If you plan to measure one of her rings, try to measure one with a similar width as the ring you want to purchase.
  • If it comes down to guessing, err on the large side. You want the ring to be able to slip onto her finger when you’re proposing!
  • If the ring you select does not fit when you receive it, we are happy to resize it for you within 30 days. Please contact us for return instructions.
