If you want your engagement to really be a surprise, and your partner hasn’t dropped loads of hints about all things rings, you may need to do some digging on how to figure out your girlfriend’s ring size all on your own. Because someone’s ring size isn’t really a casual thing to mention in conversation, your stealthiness is absolute key. Just pretend you’re Betty Cooper on any given day and you’ll be set. (If you don’t get that reference, then you don’t watch Riverdale, and should be ashamed.)

When you pop the question, you want to be sure the ring is sized correctly, and in the style that she wants. These details will make the proposal all the better if you both don’t have to go back to a jeweler later to resize the ring. It may sound too dramatic, but these moments are super important and you want to make sure you are prepared.

Here are some easy ways to find out her ring size, so you can get on with that special proposal!


DIY

While your significant other is deep asleep catching some Z’s, quietly wrap a paper ring sizer around her left ring finger. Try to do this without shining your iPhone flashlight in her eyes, and don’t shuffle with the paper too much, as it’ll be noisy and blow your cover. This is going to be the most foolproof method for finding out her ring size without her knowing. Unless, of course, she wakes up. We can’t help you then.

Ask Her Friend

She may be dropping Easter eggs to those closest to her for this very mission. Casually ask her mom, sister, or best friend. Do your due diligence, because maybe they do know her ring size. This option does, though, run the risk they tell her you asked – just something to remember if you want her to be totally surprised.

Take Her Ring In

Bring one of the rings that she wears on her left ring finger to us and we can size it in our store. We are trained professionals, after all, and this way, you have no doubts on whether you did anything incorrectly. Make sure you take in a ring you know fits, and one she doesn’t wear every day – so she doesn’t suspect a thing.

Play Dress Up

Have her try on someone else’s ring in front of you at a party or family gathering. This one leans to the obvious, but if you’re in a serious relationship and have discussed getting married, she probably already knows you’re considering proposing anyway.

Ask Her!

This is our personal favorite strategy and ensures you won’t mess the ring-sizing up. If your girlfriend is a bit obsessive about getting details right and would probably freak out over any small error, this is the way to do it. Ask her for her ring size. She’ll appreciate your consideration in making things run smoothly for when you do ask her the big question.

Once you know her size, and picked out the ring, all that’s left is the unforgettable proposal.
