Online ring shopping has never been easier, but not knowing your ring size could mean you order a beautiful ring that’s too loose or uncomfortably snug. You don’t want a ring that slips off or gets stuck--the proper fit will protect your ring and prevent resizing. Knowing your ring size is essential when ordering from us because we want to make sure your ring is ready to wear as soon as you receive it. If you’re planning to pop the question and want to keep an engagement ring a surprise, you’ll want to be sure to know her ring size. We’ve created a ring size guide and chart so you can find your ring size, or hers, without leaving home.
Since there’s no one-size-fits-all way to find your ring size, you can choose which method works best for you based on time and convenience.
To find your ring size on your own, you can use a ring sizer. You can purchase a ring sizer on a keychain, a plastic mandrel, or an adjustable ring size gauge. If you choose an adjustable gauge, use the chart below to determine which size corresponds with your measurement.
You may need to make a quick or last-minute purchase and have no time to see a jeweler or find a ring sizer. In this case, a string, piece of floss, or strip of paper will suffice. A strip of paper may be the simplest to mark and measure. Measure the circumference or diameter in mm and compare it to the ring size chart.
If you already have a ring that fits well, measure it! Use a ruler and the size chart to find your exact size.
Getting sized by a jeweler is your safest option. Jewelers use professional measuring tools and years of experience to help you determine which size ring you’ll need for the particular style you want. To measure your finger, a jeweler will use a large ring with small metal rings in each size attached to it and try them on your finger until they find the best fit. If you’d like to find the size of a ring you already own, a jeweler will slide it on a metal rod called a mandrel that increases in size in measured increments toward the base.
Once you’ve found your ring measurements, compare the circumference or diameter in mm with the ring size chart below. Diameter is the inner measurement across the ring, and circumference is the measurement around the inner ring. If you’re shopping from an international site, use the chart to find the size conversion. The U.S. and Canada use the same ring sizes. The UK, Europe, and Australia use different sizing, and so do Italy, Spain, and Switzerland.

Size 6 is the most common ring size for women, but the average size ranges from 5 to 7. Ring sizes are the same for men and women, ranging from 3 to 13. Guessing ring size by height and weight is risky. Measuring is a much better option. A woman with above-average weight may have slender fingers, or a petite woman may have wider knuckles. Weight gain will generally add width to a finger, but if a woman’s finger is smaller than average, then she may still have a small ring size if her weight increases.
The easiest and most accurate means of finding your girlfriend’s ring size is to ask her or to go together to get her ring finger measured, but both options can ruin a surprise proposal. Here are a few suggestions for keeping your engagement ring a secret.
Staying subtle is key. If you’re not so great at keeping things natural under pressure or have a horrible poker face, this may not be the best option for you. But if you can weave ring size into a conversation so she doesn’t even blink twice, then you have a quick and easy way to find your answer. Try complementing her hands or fingers while holding them, and then try to guess her ring size. Chances are she’ll be eager to drop a “hint.”
Reach out to the people who know her best and may have even purchased a ring for her before. If none of her family or friends know her ring size, they may be able to find out and report back to you so you don’t have to risk asking her yourself. But make sure you trust whoever you ask to keep your secret!
If you can snatch one of her rings without her noticing, you can take it to a jeweler and then return it. Or if you have just a few minutes to sneak into her jewelry box, make sure you’re equipped with your string and measuring tape.
If there’s no way you could borrow a ring without her noticing, try to take an imprint of one or trace it onto a piece of paper. Just be careful not to damage the ring in the process.
Most ring sizes can be adjusted, but it depends on the material and design of the band. To resize a ring, a jeweler will create a small incision and add or remove metal to the band. Sometimes the metal is stretched when a larger size is required. If an expert jeweler resizes your ring, you should not be able to tell by looking at it.
Yellow gold and sterling silver rings are the easiest to resize. Bands made out of metals like titanium or platinum are too hard. Rings with custom engraving or gemstones around the band cannot be resized without compromising the construction. If you are planning to purchase a ring with an intricate band, it’s especially important that you size it properly.
Our rings are one-of-a-kind creations and are offered only in specific sizes online. If you love a ring, but don’t see your size, contact us and we’ll guide you to a beautiful ring that fits like a charm. If it doesn’t, many of our rings can be resized, and we’ll work with you until you get the perfect fit. Call or email us at info@qevon.com if you have questions about any of our rings.
