How to get her ring size
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.
• Knowing the most common ring size can help you make your choice. The average ring size for women is 6 to 6.5, and the average ring size for men is 9 to 10. When no other information is available to you, selecting one of these standard ring sizes is your best choice.
