Covert Ways To Estimate Her Ring Size

We understand that buying a diamond is a significant purchase. That is why each Clean Origin lab-created diamond is independently verified and graded using the same scientific rigor applied to mined diamonds. However, even the best diamonds aren’t enough if the ring is a miss, and the last thing you want to do is drop potentially hundreds or thousands of dollars on a ring, only to discover that it won’t fit on your beloved’s finger.

Wondering how to find out ring size without having to ask? Here, we cover three tried-and-true methods, so you’ll be able to get the right fit for the most important ring your partner will ever wear.

Method 1: Measure a Ring She Wears Now

If you’re wanting to have a surprise proposal, secretly “borrow” and measure a ring that fits her left-hand ring finger (or the finger you intend her to use). Tread carefully. You don’t want her to find out, and you definitely don’t want to accidentally lose the ring! Depending on how much time you’ll have with the ring before she notices it’s gone, here are a few tactics to consider to find her ring size:

1. Take it to a jeweler. If you have a few hours, take the ring to a local jeweler to size it professionally. While this takes some time, it’s also the most accurate way to find her ring size.
2. Invest in a ring mandrel. To quickly and accurately measure the ring yourself, purchasing or borrowing a ring mandrel (also called a ‘ring sizer’) is a reliable and accurate option. Slide the ring down the mandrel. The line where the ring stops indicates the ring size.
3. Use the ring sizing chart. Be sure to print it ahead of time and use a ruler to double-check that it is precisely to scale. Move the ring from circle to circle until you find the best match for the ring’s inner diameter. If the ring lands between two sizes, always choose the larger one.
4. Trace it. Carefully trace the inside and outside of the ring on a piece of paper. Repeat several times for added accuracy. Take the paper to a jeweler for a size estimate.
5. Try it on yourself. If pressed for time, try the ring on your own fingers and see if one of them fits well. If it does, you can measure that finger later to figure out the size on your own time.

Method 2: Pretend To Shop For Someone Else

If you’re up for the acting challenge, pretend that you want to buy a ring for someone else and ask her for help. Whether it’s your sister, grandmother, aunt, or mom, picking someone whose hands closely match hers should be fine. This could also be a great way to gauge her style, especially if you ask her for advice on color and other design elements. Here are a few tactics you can apply to find her ring size:

1. Casually ask her if she knows her own ring size. As you browse for rings, say your version of, “I don’t know what ring size my mom wears. Do you know yours? I could use you as a reference.” Make sure this feels like a natural part of the conversation.
2. Ask her to try on rings. Pay attention to which size fits her best. If needed, take a solo trip to the store ahead of time to familiarize yourself with where and how sizes are listed.
3. Bring her a ring for approval. If visiting a store together is not possible, try purchasing an inexpensive ring you think would fit her. Casually ask her to try it on to make sure it “looks good” before you gift it to your mom. Pay close attention to the fit.

Method 3: Ask a Trusted Friend For Help

Enlist the help of a close friend or family member who may either already know her ring size, or who can assist you in executing the other methods. Just make sure this is someone you can trust with your secret, otherwise, it’s not worth the risk. Here are a few questions to ask:

1. Do they already know her ring size? Perhaps her mom or best friend recently purchased a ring for her as a gift. In this case, they may already know her size.
2. Are they open to having her try on their rings? If they have similar sized hands, they could try each others’ rings for fun and in the process gauge her size. The most common women ring size is 6-6.5, so knowing this could also help find her ring size.
3. Would they go jewelry shopping together? Whether at an artisan market, the mall, or even a jewelry store, they could browse for rings while also noting her size.
4. Can they ask her for her ring size? If the question fits naturally into a conversation, they can simply ask for her ring size without giving away your secret.

How To Make Your Own Paper Ring Sizer:

1. Print the image. Make sure the scaling of the page is set to 100%.
2. Measure the 3½ inches with a ruler to ensure the printout is precisely to scale.
3. Trim the paper to match the outline and cut a slit as indicated by the vertical line.
4. Insert the pointy tip of the paper through the slit.
5. Place the paper around her finger and gently tug until you have a secure, comfortable fit.
6. The number line that meets the slit indicates the ring size.
7. Consider repeating steps 4-6 a few times to ensure accuracy.

Final Considerations

Since some of these methods come with a margin of error, here are a few other considerations when finding her ring size:

1. When torn between two sizes, always go with the larger one. Going too small may result in the ring getting uncomfortably stuck on the finger, and it’s generally easier to size a ring down if needed.
2. Wider rings typically have a tighter fit and may require a slightly larger size to fit comfortably.
3. If possible, avoid measuring her ring size first thing in the morning or on extremely hot days, when fingers could be more swollen than usual.
