Preparing to propose to your true love is a significant step. But before you can find the perfect ring, it is important to determine your partner’s ring size accurately. Use the tips below and our size chart to help ensure that your engagement ring choice fits well on your loved one’s finger the first time. 

How to measure your partner’s ring size

An engagement ring is the ultimate symbol of commitment and everlasting love. While there are many ways to surprise your partner with a romantic proposal, here is how to subtly discover their ring size for the perfect proposal moment.

Borrow an existing ring

One of the easiest ways to learn your partner’s ring size is to take a look at the rings they already own. Comparing the size of these rings to the ring size chart will allow you to discover the size you need to buy. If possible, you may also want to consider taking your partner’s ring into the nearest Jeweler for further expert advice.

Do be sure that the ring you are borrowing fits the ring finger – in most Western cultures engagement rings are traditionally worn on the fourth finger of the left hand. 

Another factor that can easily go amiss is the difference between the right and left hand. The dominant hand usually tends to be a little bigger.

Bar of soap ring trick

If you’re concerned your partner may notice one of their rings has gone missing, the bar of soap trick may be a more effective method of finding out the ring size. Discreetly take the pre-owned ring and press it into a bar of soap to create an imprint of the ring size. Ensure that you rinse and dry the ring before putting it back exactly where you found it to avoid raising suspicion. The imprint can then be measured against the ring size chart to identify an accurate ring size.

Talk to friends and family

You know your partner inside out but when it comes to finding out their ring size, don’t hesitate to ask for help from other people in their life – such as friends and family. It may be that they already know what ring size they wear, or they may be able to investigate on your behalf. It’s often a more discreet route to explore.

Take this opportunity also to gather deeper insights into what your partner might be looking for in an engagement ring, whether that be the shape of the diamond or the ring setting. It will also help ease your mind, and make the decision-making process less intense. 

Involve your partner

Choosing an engagement ring is undoubtedly one of the most momentous steps in your relationship. The ring you choose will not only symbolize your enduring commitment to each other, but it will also be an eternal reminder of the love you share. For these reasons, it is essential both of you are just as pleased with what the ring represents.

Why not break traditions and take your partner engagement ring shopping? Purchasing the ring together could be a memorable experience in itself – why not spend the afternoon window shopping and trying on different designs until you find the perfect diamond together?

Useful hints

There are a few environmental and physical factors that should be taken into consideration before deciding on the size of the ring you want to buy, but remember that when it comes to guessing your partner’s ring size, guess on the large side as it’s easier to size a ring down. We also recommend measuring a finger 3 or 4 times to avoid erroneous reading.

Resizing your ring

Rings can typically be resized up to two sizes larger or smaller, depending on your setting and the type of metal. “How many times a ring can be resized depends on the thickness of the shank. The less the ring is resized the better, but it really depends on how much metal there is to work with,” says Ted Koester of Herzog Jewelers, Mitchell, KY. Resizing a ring too many times will weaken the metal and could eventually damage the ring. Whether you need to resize your ring up or down the resizing process is usually a simple one.
