How To Find Out Your Partner's Ring Size Without Them Knowing?

If you wish to keep the proposal a surprise, getting the correct ring size can be challenging. While you may know their preference regarding the type of jewel, you may not know their ring size. There are various ways to find the perfect ring size for your partner without their knowledge. 


Use one of their rings to get a size approximation.

One of the easiest methods to get your partner's approximate ring size is to measure a ring they already have. You need to make sure you pick a ring they won't notice is missing. Also, be sure to pick one that they wear on a similarly sized finger to avoid ending up with an oversized or undersized ring.

Next, place the ring on a ruler and measure the inner diameter of the ring *(see example image). Similarly, you can trace the inside of your partner's ring with a thin pan. You can then find the ring size on our online size chart.

Help from a close friend / family member

It's always helpful to "have someone on the inside" to get an accurate estimate of your partner's ring size.

  • Have one of your friends ask your partner to go jewelry shopping. In the process of looking at jewelry pieces, ask them to pay attention to what ring size goes well on your partner. They might also drop some hints such as their favorite gemstone shape, type of setting, platinum or yellow gold, and so on.


It is the thought that matters most

Even if you propose with a beautiful ring that doesn't fit perfectly, the chances are that your partner is not going to care! They will be highly touched and happy as you both embark on a journey together and will appreciate your thoughtfulness! 



Still not sure? Final Considerations

We understand it's challenging to find your loved one ring size and that most of these sneaky methods come with a margin of error.

Depending on the ring design you decide to buy, it's often a good idea to go with a size a bit larger to guarantee the ring will at least fit your partner's finger - for the proposal. It's helpful to know that the average woman ring size is between 5-8 and men is 9-11. The goal is to get the size as close as possible. We always recommend contacting us if you're unsure whether you should get a slightly bigger or smaller ring based on the ring design.  

Finally, keep in mind that at LilPetite we can always resize the ring for you at any time. If you have any more questions, feel free to contact us, and we will be happy to help.
