Planning a surprise proposal is one of the most exciting—and nerve-wracking—moments in a relationship. From choosing the perfect setting to picking the right time, there’s a lot to think about. But one small detail can make a big difference: the ring size.
Imagine pulling off the perfect proposal, only to realize the ring doesn’t fit. Too tight, and it won’t slide onto their finger. Too loose, and you risk it falling off. But don’t worry—there are several clever ways to figure out your partner’s ring size without spoiling the surprise. In this guide, we’ll walk you through easy tips to get it right.
Why Getting the Right Ring Size Matters
When you propose, all eyes (and emotions) are on the ring. If it doesn’t fit, it can take away from that magical moment. Plus, resizing a ring after the fact might not always be simple—especially if it’s a custom design or includes delicate gemstones. That’s why getting as close to the right size as possible from the start is so important.
1. Borrow a Ring They Already Wear
One of the most foolproof ways to get the right ring size is to borrow a ring your partner already wears. Make sure it’s a ring they wear on their ring finger—left hand for engagement rings. If the ring is rarely used or goes on another finger, it may not be accurate.
Once you have it, you can take it to a jeweler and have them measure it. Or, use a printable ring size chart like this one from Blue Nile to compare it at home.
2. Trace It or Use Soap
If borrowing the ring isn’t possible—or too risky—you can try tracing it on paper. Just place it flat and draw around the inside and outside of the ring. A good jeweler can estimate the size from that drawing.
Another trick? Press the ring into a bar of soap or soft clay to leave an impression. Take the imprint with you to a jeweler for sizing.
3. Ask a Friend or Family Member
Your partner’s close friends or siblings might already know their ring size or can find out without making it too obvious. If not, they might casually take your partner shopping and try on rings together “just for fun” to get the right size.
Some friends are great at pulling off these kinds of things without raising suspicion—just make sure they can keep a secret!
4. Use a String or Paper Strip (While They’re Sleeping)
This one is a bit sneaky and requires some ninja-level stealth skills. While your partner is asleep, gently wrap a piece of string or thin strip of paper around their ring finger. Mark the spot where it overlaps, then measure that length in millimeters. Use a size chart like this one from Zales to find the corresponding ring size.
Just be sure they’re in a deep sleep—you don’t want to get caught in the act!
5. Go for an Adjustable Ring or Resize Later
Still not confident about the size? Go for a temporary solution. Some jewelers offer adjustable engagement rings that can later be resized. Or choose a style that’s easy to resize if needed.
If you do end up needing a resize—or if the ring gets damaged or bent—it’s a good idea to visit a trusted local jeweler. In many cities, professional jewelry repair and resizing services in Turlock are readily available. Whether it’s fixing a bent band or adjusting the ring size after the proposal, a skilled jeweler can help make sure the ring fits perfectly and looks as good as new.
It’s always a good idea to have a trusted jeweler nearby for post-proposal polishing, cleaning, or repairs—so your ring continues to shine just like your love story.
6. Use Your Partner’s Glove Size (or Compare Fingers)
Here’s a trick not many people think about: glove size. If you know your partner’s glove size, jewelers can often estimate the corresponding ring size.
Another trick is comparing fingers. If your pinky or ring finger is close in size to theirs, try a few rings on your own finger and mark where it fits. Then, take that ring to a jeweler for measuring.
Final Thoughts
You don’t need to be a detective or a mind-reader to find the right ring size for a surprise proposal. With a little creativity—and maybe a little help from friends—you can get it pretty close. And if it’s not 100% perfect, that’s okay. What really matters is the love behind the ring.
Just remember: Don’t let ring sizing stress ruin the magic of your proposal. Focus on the moment, and let professionals help with the rest.
