You found the one person you want to spend the rest of your life with and are ready to get down on one knee and propose. You can envision what the engagement ring will look like or may have already found the perfect ring, but there’s just one problem… you don’t know her ring size. You’re hesitant to ask her outright because that would ruin the surprise, so how do you go about finding out what her ring size is? Here are some of our suggestions.

  • Borrow one of the rings she wears and bring it into a local jeweler so they can determine its size. Just make sure you know which finger (and hand) she wears it on. Since not all fingers are the same size, we don’t want to present her with a ring that perfectly fits her thumb but is way too large for her ring finger… If you know which finger and hand she wears it on, we can get a better idea of what her ring finger size is.
  • If you aren’t able to borrow her ring for an extended period of time to take to a jewelry store, there are several things you can do instead. You could make an indentation of her ring on a bar of soap or another similar item and bring that into a jeweler to determine the size. Or you could trace the inside of the ring on a piece of paper and bring that into a jewelry store. Another option would be to place one of her rings on your finger and make a note of where it rests.
  • Ask one of her friends or family members to help you out. You could make a suggestion to a close friend or family member to take her shopping near a jewelry store and then persuade her into stopping into the store. While in the store, this person could encourage her to try on different rings and if the opportunity arises, get her ring finger sized. Just make sure the friend or family member won’t accidentally spill the beans and ruin the surprise.
  • If she’s a deep sleeper, wrap a piece of string around the base of her ring finger (remember, it’s the finger in between her pinky and middle finger on her left hand) while she’s sleeping and mark the point where the string meets. A simple online search or visit to a knowledgeable jewelry store should be able to tell you which ring size the length of the string correlates with.
  • Compare her ring finger to one of your fingers. The next time you hold hands, make a mental note of how her ring finger compares in size to your fingers. Is her ring finger close in size to your pinky? About half the size of your thumb? While this method isn’t the most accurate, it does help to have something to easily compare the size of her finger with.
  • Ask an experienced jeweler for his or her opinion. Jewelers work with rings all the time, so we have a sixth sense about ring sizing. After asking some general questions about the bride-to-be, a jeweler should be able to get a better sense of what size ring will fit her best.

If none of these ideas lead to the correct size ring, the good news is that when you purchase a ring at Kloiber Jewelers, we’ll size the ring as a courtesy. So you can surprise her with that ring and bring it back to Kloiber Jewelers to have it resized at no extra cost to you!
