How to Measure Ring Size for a Surprise Proposal (While Keeping It Thoughtful)

How to Measure Ring Size for a Surprise Proposal (While Keeping It Thoughtful)

Love, Courage, and a Little Bit of Clever Planning

Congratulations! You’re about to ask one of the most important questions of your life. And let’s be honest—popping the question is exhilarating, a little nerve-wracking, and a whole lot of magic. But before you get down on one knee, there’s one crucial detail to figure out: their ring size.

If you’re trying to keep the proposal a surprise, you might be wondering how to get their size without them knowing. The key is being thoughtful and intentional, rather than sneaky. Let’s break it down step by step.


Five Ways to Find Their Ring Size (Without Ruining the Surprise)

1. Borrow a Ring (With Their Permission)

If your partner wears rings, you can ask if you can borrow one for reference. Here’s how:

  • Find a ring they already wear on their left ring finger (this part is key—sizes vary between fingers!).

  • Borrow the ring briefly to measure it using a printable ring sizer or stick it into a moldable dough.

  • If they ask why, be honest. You can say it’s for a future gift or a fun project.

2. Ask Friends or Family for Help

Your partner’s loved ones might already know their ring size, or they may be able to find out naturally in conversation.

Here’s how they can help:

  • A close friend can casually bring up engagement rings in conversation.

  • If your partner loves to shop, suggest they go ring browsing together for fun.

  • A family member might already know from past gift-giving.

Keep the group small—too many people involved increases the risk of someone letting it slip.

3. Take Them Ring Shopping  at Bloomstone Jewelers in Annapolis (Casually)

If you and your partner love shopping together, you can casually suggest checking out our store.

  • "Oh, I've never seen this store before, let's take a look..." should work.
  • Let them try on rings and note which size fits best. You can even call us after shopping. We're happy to help.

  • Ask their opinion on different styles—it’s a great way to get insights into what they love.

  • If they ask why, you can say you’re thinking about a future gift or just want to see what they like.

4. Take a good guess and ask for resizing after the proposal

If you’re not 100 percent sure about their size, choosing a ring that can be resized is a great option.

  • Many engagement rings can be adjusted up or down a size after the proposal.

  • Some jewelers offer temporary settings that can be exchanged for a custom fit after the engagement.

What Not to Do When Measuring Ring Size

While creativity is key, there are a few things to avoid:

  • Do not borrow a ring without asking. Taking their jewelry without permission can cause unnecessary stress.

  • Do not assume all fingers are the same size. Ring sizes vary from finger to finger, so always check the left ring finger specifically.

  • Do not overcomplicate it. Sometimes, a simple approach is best. Stick to easy methods.


What If You Guess the Wrong Size?

First up —don’t stress. If the ring doesn’t fit perfectly on the big day, it is completely normal to have it resized.

  • Most engagement rings can be resized—a quick trip to a jeweler and problem solved.

  • If it is too big, you can place a small temporary adjuster inside until it is resized.

  • If it is too small, try slipping it onto a different finger for the moment and laugh about it later.

No matter what, the moment itself will be perfect—because it’s about love, not logistics.
