How to Buy an Engagement Ring Without Knowing the Size

Buying an engagement ring is one of the most exciting moments of your life, but what if you don’t know your partner’s ring size? A too-tight ring is uncomfortable, and a too-loose one might slip right off! But don’t let this tiny detail spoil your big surprise. With a little creativity, you can still pull off the perfect proposal.

Here’s a foolproof guide to finding the right ring size without ruining the surprise!

1. Borrow One of Their Rings (Secret Agent Style!)

One of the easiest ways to get their ring size is by borrowing a ring they already own.

Here’s how:

• Pick a ring they wear on their ring finger (left hand for most, but check!).
• Sneak it to a jeweler for measurement.
• If you can’t take it out, trace it on paper or press it into soap for an imprint.
• Pro Tip: Act fast! Make sure to return it before they notice it’s missing.

2. Ask Their Best Friend or Family for Help

Chances are, someone close to them already knows their ring size. If not, their friend can easily nudge them into trying on rings “just for fun.”

Smooth Move: A sibling or friend can casually mention jewelry shopping and slip in a question about ring sizes.

3. Compare Their Finger to Yours

Ever held hands and thought, Wow, their fingers are way tinier than mine? If so, you already have a rough estimate! Try slipping one of their rings onto your own finger and note where it stops.
Jeweler Hack: Mark the stopping point and get a jeweler to measure that spot.

4. Use a Ring Sizer App or Printable Guide

Modern problems require modern solutions! Many jewelers offer free ring sizing apps or printable guides.

What to Do: If you can sneak a ring for a few minutes, match it up against a digital sizer or printable chart.

5. Observe Their Hands Like a Detective

If your partner has engaged or married friends, compare their hands. Are they similar in size? If their friend knows their own ring size, you can make an educated guess.

6. Choose a Resizable or Adjustable Ring

If you’re unsure, opt for a resizable engagement ring or a style with a simple band that’s easier to adjust later. Many jewelers offer free resizing within the first few months!

7. Guess a Size (But Choose a Slightly Larger One!)

When in doubt, go slightly bigger! A large ring can always be resized down more easily than a small one.

Caution: Don’t go too big—rings that are way off might need complete remolding.

8. Turn It Into a Fun “Ring Game”

If your partner enjoys playful moments, turn it into a game.

Ideas:

• Playfully measure fingers for “no reason.”
• Try on rings together “just for fun” at a store.

9. Check Their Jewelry Box

Sneak a peek inside their jewelry box. If they have rings, test which ones fit their ring finger.

Be Stealthy: Take a quick pic or note the size of any existing rings.

10. Consider a Toi et Moi Engagement Ring

Want a unique and flexible choice? Toi et Moi engagement rings (two-stone designs) often have open-ended styles, making them more forgiving in size.

Bonus: They also symbolize two souls coming together—perfect for romance!

What If You Get the Size Wrong?

First off—don’t panic! Most engagement rings can be resized, and many jewelers offer one free resizing after purchase. If resizing isn’t an option, temporary adjusters can help the ring fit until an adjustment is made.

Conclusion

Buying an engagement ring without knowing the size doesn’t have to be stressful. With these clever tricks, you’ll get as close to the perfect size as possible—while keeping the surprise intact! The most important part? The love and commitment behind the ring!
