Brilliant Earth jewelry expert Jessica Anand is frequently asked by our customers about how they can find out their girlfriend’s ring size without her knowing. Here we’ve shared some of Jessica’s best tips and tricks!
Request a Free Ring Sizer
We are happy to send you a complimentary plastic ring sizer so that you can easily measure your ring size at home. Plastic ring sizers shipped to the US and Canada will arrive within five to seven business days and delivery time to Australia may take longer.
Be Subtle
If you are absolutely set on a surprise proposal but you still want to find out her ring size directly from the source, ask your girlfriend in a very subtle, smooth way. You can pretend, for example, that you are going to buy a ring for your mom/sister/aunt/niece etc. Make sure that this pretend recipient is someone whose hands are similar in size to your girlfriend. Casually ask what her ring size is for reference. If you really want to beef up the ruse, purchase an inexpensive ring and show it to her. Have her try it on and everything! Maybe afterward you can actually give that ring to your mom/sister/aunt/niece to appease your guilty conscience!
Ask Her Friends
A great way to find out her ring size is to ask one of her friends. Friends occasionally have this insight! And, if the friend doesn’t know right away, she can be the one to ask (nonchalantly). Even better, ask the friend to take your girlfriend engagement ring shopping “for fun.” Have her get professionally sized and ask her friend to report back to you. It’s best to choose a friend who might have once had acting aspirations!
Borrow One of her Rings
Another method is to snag one of her old rings for a day. You need to be careful with this method because it might backfire on you! Make sure that you grab a ring that she wears on a similarly sized finger, the ring finger of her right hand being the optimal choice (unless, of course, she wears a ring on her left ring finger, which is less likely). Even if you bring in a thumb ring we can usually come up with a close approximation of what size her ring finger will be. If you choose this option, make sure that you choose a ring that isn’t overly important to her and wouldn’t cause any emotional distress if she notices it missing!
Leave a Trace
If you are terrified of losing one of her rings try this method instead. Take one of her rings and place it on a piece of paper. Draw a circle on the inside and outside of the ring. Do this several times to make sure that your ring traces look consistent. We can usually figure out the diameter of her ring from your sketch!
Enlist a Friend
If one of your partner’s friends is engaged, ask her friend to let your girlfriend try on the ring. This will put you in a ballpark size range to start out with. You can also use this as an opportunity to ask what she thought of her friend’s ring (in private) and try to do a little sleuthing as to what style of ring she would like for herself.
Compare Fingers
This method is a little more difficult, but if you are desperate, go ahead and try it out! When you are holding her hand,see if one of her fingers is similar in size to a finger of yours. For example, her ring finger might be as big as your pinky. This method isn’t amazingly accurate, but the more information we have on her ring size the closer we can get!
Ask Your Partner!
There are some people in this world who like to do things the hard way, and then there are those who are very straightforward. If you and your partner have been discussing marriage for quite some time, ask her outright what her ring size is! Don’t worry though— you can still have the element of surprise. After all, she doesn’t know when you’re going to ask her, or how! If she doesn’t know her ring size, she can find it using our printable ring sizing guide.
Keep in Mind:
The two most accurate ways to confirm ring size are to come in and have your partner sized by us in person or have them visit a local jeweler. Using one or several of the methods above will result in a very good approximation, but there is always the risk that it will be slightly off.
Please note that for custom designed rings, we highly recommend visiting a local jeweler or coming in and having her finger sized with us, as custom pieces are final sale and may not be able to be resized in the future. Err on a larger size so that it will be guaranteed to slip over her finger when you propose.
Interesting Ring Size Facts:
- Our dominant hands tend to be slightly bigger (so make sure you are measuring for her left!)
- The most common women’s ring size is 6 to 6.5.
- Wider rings have a tighter fit than thinner bands, so if you borrow a ring for us to measure, try to make sure that it is the same width as the ring you plan on purchasing.
- Brilliant Earth is happy to ship you a free ring sizer, so that you can measure your ring size in the comfort of your home!
What if I just can’t figure out the size?
If you simply can’t figure out the size or you don’t want to risk it, consider choosing a temporary setting to propose with. Our temporary setting is our 18K White Gold 2mm Comfort Fit Ring. You have sixty days to propose, have her properly sized, and send the ring back. Once you have her perfect size, we can set your diamond in your ideal setting. This way she gets to see the diamond you chose, but there isn’t the risk of having to resize the actual setting. Please contact us about this option, so we can explain the exact process to you! This is also a great option for those who don’t know whether to purchase an engagement ring before or after proposing.
Good luck!

and did you know that the one thing that has measurements of the same between men and woman are ring szs.all you have to do too is measure your finger too and ask her to try on your ring.it will give you a ballpark figure also.
How many of your friends know your ring size? Even better, ask the friend to take your girlfriend engagement ring shopping, REALLY? If one of your partner’s friends is engaged, ask her friend to let your girlfriend try on the ring? These are options for someone trying to buy a ring as a surprise? I have another one for you. Take your girlfriend to a wedding dress store and have her try one on, you know “for fun”. Then rent a white limo and drive her to a big church and have her walk down the isle, again just “for fun”. You see where this is going? Surprise…………………….
How about… I dunno, taking a ring she wears a lot and trace it on a piece of paper. (Inside of the circle and out)
Why not just have one of her friends say something like hey can I borrow that ring its so pretty and being a good friend shed say yea but just give it back and BOOM you have a ring size
There is one way not listed here…. Try on one of her rings. Make a mental note of where it stops on your finger. Go to a jeweler and try on sizer rings until one hits the same spot on your finger. There you go.
Find a pic (or take one in secret – perhaps while she’s sleeping) of her hand next to an object that can easily be measured. Then, in photoshop or some other image edit application, find the ratio between the object diameter and her finger diameter and multiply that by the diameter of the object. Once you know the diameter it’s just a simple calculation to get the circumference (pi x D). Obviously, for best results get as close as possible and use the best camera you can find.
I would like a free ring sizer please.

I read somewhere else that you can take a ring you know fits her and press it into a bar of soap. Take the soap to a jeweler.
My girlfreind is kind of a tomboy. She rarely ever wears jewelery other than the necklace i got her e while ago. Plus i don’t know what she’ll like. If she had a sister i would go to her, but her mom has about the same size hands… lol just because i posted this i now know what to do!
I have a suggestion for all of you. How about you’ll all stop throwing your life away like that. Marriage these days is nothing but a business proposition – one that has the guy on the losing end of it. Are you really willing to do that? And then feel guilty for figuring out her ring size when you’re about to blow $50k on some carbon-based blingy stone?
Hans…. sounds like you might have lost in love….. whether or not that’s true, don’t be so negative to the rest of us because of your experience….
And now for the best answer…..her ring size is the same as her shoe size……(minus the narrow or wide). I know this sounds strange, but to my knowledge, this has always held true. So when she isn’t looking, check out one of her shoes…????
Who cares !
I am currently working in a differnt country.
My questions are:
1. Does it make sense if I send the ring despite we’re faraway to each other?
2. Which other way can I know her ring size apart from the listed ones above?
Hi John,
If you are far away from her, you could ask one of her friends or family members for her ring size. If none of them know it, you could also enlist a friend or family member back home to try on one of her rings to compare ring sizes. Good luck! Our jewelry specialists would love to help you with any further questions and can be reached by calling 800.691.0952.
Please let her pick her own ring! I got an awful ring. The store wouldn’t take it back. A $3,000 ring spent 15 years in a drawer until it was pilfered by a cleaning lady!
Please let her pick her own ring. My ring was so awful. The store wouldn’t take it back and the owner showed me 3 even worse ones. The 3,000 ring stayed in a drawer for 15 years until the cleaning lady stole it. It should be a Class A Felony to allow an unescorted man into a jewelry store!
NancyDrew you could have sold it if you really wanted. You should be grateful you even got a ring and that someone would marry you!! Some of us aren’t that lucky!!
The shoe vs ring is NOT TRUE… I wear a size 8 shoe and a 6 ring. No.
Diane-
I work in jewelry and I can tell you that women’s shoe sizes have NOTHING to do with ring sizes.
Myself as an example wear a 5.75 ring and a 9.5 shoe. If I tried to wear a 9.5 ring on my ring finger it would fall off
Why not offer to buy her a small promise ring of greater things to come. I know I LOVED my promise ring when I got it, but if she is eager, she will give you the facts you need!
I came here hoping to leave with some insight. The first two suggestions are really awful ?
Im sorry but I hate that everyone is dictating about others opinions. Whether or not its true. I know that my husband asked me on our third date. He asked, Baby, what kind of rings do you like? I answered. When I was in Walmart with him I tried on some of their rings and that’s when he got my ring size. All that youran has to do is be a spy, really. He’ll surprise with your ring. Mine wasn’t expensive. I know that a woman on here said she hated her ring. If its a 3,000$ ring I wouldn’t hate it. Mine was really cheap. I’m sorry but it shouldn’t matter how much it is. What should matter was that he became brave enough to ask you for your hand. My husband for the longest time has put himself down for buying me a cheap ring. I have told him that I love him and that’s all.
I’m dreaming. These rings are beautiful and would look perfect on my size 7.5 finger.
Ihave r??d so many posts ?oncerning the blogger lovers but this paragraph is really a good p?ece of ?riting, keep it up.
Nancy Drew is right. Let her pick the ring. She’s going to wear this on her hand ever day for the rest of her life.
You can still make the proposal a surprise, with or without the ring.
Or a “surprise” will ruin what should be a happy time.
Actually, the ring size/shoe size thing does typically hold true… Except it’s your size in MEN’S shoes! (Usually about two sizes smaller than your typical women’s shoe size). Also, bear in mind that “fashion” shoes, like similar clothing, tend to vary somewhat wildly in sizing, so it’s best to use a winter boot or athletic shoe for this purpose. Good luck!
And yeah, discuss rings early in the relationship, then file the info for later use, if possible. That way, you’ll also know the styles she likes and if she has certain expectations of size or doesn’t even care for diamonds, etc.
I haven’t checked in here for some time since I thought it was getting
boring, but the lst few posts are great quality
so I guess I will addd yyou back to my everyday bloglist.
You deserve it friend 🙂
Totally believe this – its not always easy to
get points such as this across but you’ve done an admirable job to your readers
Trying to propose without anyone knowing or saying anything
Or, if your girl is into scented candles, tell her it’d be fun to get her one of the “candles with a ring in them” (FragrantEarth, etc.) and tell her you need her ring size to order it. It’s not quite as obvious a move as buying a ring all by itself, since it’s about the candle as much as the ring. Worked for me!
