Guess A Ring Size

How To Guess Your Girlfriend's Ring Size

We suggest that you order the correct size if at all possible, but if it HAS to be a surprise, and you don't want to use the ring sizing methods we have provided on the site, here are some ideas that may help you make a pretty good guess.

Ask her friends or relatives. If your girlfriend has any inkling that you may be proposing in the near future, she may have told them her ring size.

Does she wear other rings? Does she occasionally remove them for showering, etc? Does she keep them in a jewelry box?

• Option 1 - When she's not around, temporarily "borrow" a ring that she wears on her left hand ring finger and trace the inner part of the ring on a piece of paper. Be sure to return the ring immediately and then match your tracing to one of the ring sizes on the printable ring chart available on our site. Or, match it to the FREE ring sizer that we will be happy to send you.

• Option 2 - Carry around a small bar of soap in your pocket. A hotel soap is the perfect size. When she's not around, press the ring into the soap to make an imprint. Be sure to wipe the soap residue off the ring and return it to its proper place. When you're alone, use the FREE ring sizer to match the imprinted circle. Just lay the ring sizer over the imprint and find the ring size that best fits the imprint.

• Option 3 - Take her ring and place it on one of your fingers. Draw a line around your finger where the ring falls. Use our FREE ring sizer to measure the marked area on your finger.

• Option 4 - Take the ring and slide it down a tapered candle. Mark the candle where it falls, then use the FREE ring sizer to measure the marked candle.

Do a trial run. If you don't plan on proposing for quite some time, present her with a lovely, but inexpensive fashion ring on her birthday or some romantic holiday. Giving her this ring can be "practice" for the real thing. And although you may not buy the right size initially, you will more than likely find out her correct finger size afterwards.

Find an accomplice! Get her mom or one of her friends, whoever would be appropriate (and trustworthy of your secret) to go shopping with her and get her to try on rings at any jewelry store. Everyone can get their fingers sized! They can excuse this as speculative fun, and your girlfriend may not suspect a thing.

Go shopping with her. Is there anyone else you could potentially say you're picking out a ring for (a mother, grandmother, etc.)? That way, you could go ring shopping with her and get her to model different rings so you can see what they look like. You could discuss ring sizes, and then take this opportunity to get her finger sized at the store "just for kicks". You will also be able to get a good sense of the styles of rings she prefers.

If she is a heavy sleeper, use the FREE ring sizer on her finger while she is sleeping.

Buy a fake ring...some $10 thing from a department store as a "surprise". Then tell her you want to go shopping together for the real thing at DanforthDiamond.com. This way, she can pick the ring of her dreams, and in the correct size.

But just WHAT is the average size woman you ask? According to statistics, the average American woman is 5'4" tall and weighs 140 pounds. Using this statistic, you may be able to make a good guess on your girlfriend's finger size. Does she have a small, average or large frame? How much does she weigh? (Don't ask her weight if you don't know it...this could be dangerous if asked at the wrong time!). But do take notice of her frame, her weight and her hands. Also notice if she has large knuckles as well. Her fingers may be slender, but if her knuckles are large, she may need a larger ring to fit over the knuckle.

More than likely, if she is small-framed with slender fingers and weighs under 120 pounds, her finger size could range from a 4 to a 5. If she is larger-framed with thicker fingers and weighs over 150, a good guess may be in the 7-9 range. For best fit, the ring should be snug with a slight resistance when pulled off. Wider rings should be a little looser. You will have to use your own judgement, but using these guidelines could be helpful to you in making an educated guess.

Ring Sizes for Small, Medium, and Large Hands

The average ring size for a man, by the way, is a 10, so if you are an average-size man (average medium frame being 5'10" with a weight of 180 pounds) with average-size hands, you may be able to use your own hand for comparison. If her hands are a lot smaller than yours, she may very well wear a size 4-5 on her ring finger. Be aware though, many men loose their wedding bands because their bands are too loose. If you are not used to wearing a ring, the correct size may feel tight at first.

We'd like to point out however, that EVERY woman is different, and there are no guarantees that figuring out her body type will correctly determine your girlfriend's ring size. So, we don't strongly advise going with this option. Ladies ring sizes can be as small as 4 and go up to a 10, so there's lots of room for error using this method.

To play it safe, you could order the ring at a size 6 or 7, and present it to your girlfriend. She can then determine the correct size she needs, then return it to us and we will resize it once for FREE.

Please note that if you order a size 6 or 7 ring and you choose to have it resized to your "guessed finger size", this counts as the 1 FREE resizing. If you have not guessed correctly, and it needs to be sent back, there will be a $25 charge for the 2nd re-sizing.

Keep in mind that some of our fancy rings, because of the way they are made, may not be easily re-sized. (Our rings with diamonds all the way around, are a good example). It would be very important to order one of these rings at the correct size. Please feel free to call one of our expert jewely consultants at 1.877.404.RING if you have any doubts or questions about your order.
 
Learn the Different Ring Sizes for All Her Fingers

If you regularly buy jewelry for another person such as your girlfriend, wife, daughter, etc. we've created a nifty Hand Chart that will help you keep track of her different ring sizes. This way, you will never have to ask her in the future, what ring size she wears!

Download a PDF of our Hand Chart for all ring sizes. If you are not able to download and printout this chart, you can easily create one yourself.

Have her trace the outline of both of her hands on a piece of paper. On each finger outline, have her write-in her correct finger size. You can use the FREE ring sizer from Danforth Diamond to size each finger. Because fingers are not always the same size on each hand, be sure to do BOTH hands.

Label them Left and Right and put her name at the top, along with the date. (Finger sizes can change over time due to age, weight gain or loss, and climate. So you may want to re-examine or update this hand chart every five years. File it away in special place, and you'll be ready for every special occasion!
