How Can I Secretly Figure Out Her Ring Size?

You’ve found the love of your life and want to commemorate your commitment with a beautiful ring. Congratulations! Once you take this step, it's time to find the right ring, but how can you be sure it’s the perfect size?

How Do You Know What Ring Size Your Girlfriend Is?

There are a few ways to establish what ring size your significant other is:

• Ask: If you’re at the stage where you’re considering a ring, you and your girlfriend have likely already talked about your future. You can always ask her about her ring size and the kind of ring she wants while making the proposal and actual ring a special surprise.
• Ask her friends or family: Does she have friends, a mom or a sister who might know her size? They can also have her try on some rings and compare. Just remember that letting someone in on your secret increases the chances your plan will slip out, so choose your helper carefully.
• Take her with you: More couples are buying statement pieces such as engagement rings together. This helps you get a perfect fit and allows your partner to have a say in the ring, so you’re both thrilled with the decision.

How to Discreetly Get a Ring Size

If you want your ring to be a special surprise, there are a few sneaky ways to get a size:

• Borrow a ring that fits her: If she has a jewelry box, is there a ring in there that fits her? Does she take off her ring to go to the gym or take a shower? If so, sneak the ring away and trace it, then use a ring sizing tool to figure out the size. Just make sure to notice which finger she wears that ring on! All fingers are different, even if is the same finger on the opposite hand!
• Guesstimate: Compare her fingers to yours. Is one of your fingers close to her ring finger? Do you know a girl with similar size hands? Guess based on that or use math. The most common ring finger size for women is size six. Consider whether your girlfriend’s hands are larger or smaller than average and size up or down accordingly.
• Enlist her help: Tell your girlfriend you’re getting a ring for your sister, mother, or other relative. This should be someone who has a similar size ring finger. Ask your girlfriend to try on a few inexpensive rings to “test” them and purchase an inexpensive one to give to your relative. This process will get you the exact size in a sneaky way.

If you’re not getting her exact ring size or are guessing, make sure you plan on buying a ring you can easily resize to the correct fit. Always buy a size larger than you think you need, as it is much easier to adjust a ring size down.
