How to Find Her Ring Size

So you've finally decided the time is right to pop the question!

You've picked out the perfect engagement ring from Tapper's, you have the perfect proposal planned out, but one thing is standing in your way: you don't know her ring size. Well, don't fret. We've compiled a brief list of tips to help you secretly find your future fiancé's ring size to complete the perfect surprise proposal.

Phone a Friend

Get in touch with a friend or family member of your significant other. They may have bought her a ring as a gift before, or the topic of ring size could have popped up in conversation. If they don't know, then you can always recruit them as an accomplice. Have someone take her “window shopping” for a ring and get her to see what her ring size is for “fun”.

When the ring can't leave the home

If you're unable to bring her ring to us without her noticing it's missing, there's several ways you can estimate the size without taking the ring out of the home. First, you can try the ring on yourself and mark on your finger where it falls. Then you can come in and have us find the size that falls in the same place. Also, you can make an impression of her ring in a bar of soap and bring it in for measurement. One more method is to trace the inside of her ring with a pencil and have us match the size.

Tell her it's for someone else

You might be able to get her to divulge her ring size by telling her you want to buy a ring for your sister or mother. Tell her you want to get an estimated size for someone else and either ask her to try on a ring or ask her outright what her size is. Beware though, this method could be a dead giveaway if not done right!

”Borrow” a ring

If you can get your hands on a ring that your girlfriend wears, you can bring it in to Tapper's and get it measured. However, in order to get an accurate measurement, you'll need to be sure that the ring actually fits her properly and is worn on the correct finger (left ring finger), as all fingers are different sizes. If she doesn't wear a ring on that finger, you can settle for an estimated measurement for another finger, but be aware that the ring will most likely need to be re-sized.

When in doubt, size up!

A ring is easier to re-size if it's too big, and in most instances, re-sizing is a simple matter. Just be aware that thin bands or those which are intricately covered in gems might not be able to be re-sized. Make sure you check with us first to determine if the ring is re-sizable. Also, if you're guessing her ring size, it's important to know that rings which have a wide band will need to be larger than her normal rings.


Using one of these tips, you should be able to get a fairly accurate measurement of her ring size and be well on the way to spending the rest of your life with the woman of your dreams! Just remember to keep in mind these three important points:

  • You need to find the size of her left ring finger. Rings worn on any other finger aren't likely to give an accurate measurement.
  • When in doubt, size up because it's easier to re-size down.
  • Make sure the engagement ring is re-sizable.

Good luck and we'll see you soon!
