Engagement Ring Sizing: How to Secretly Determine Her Ring Size

Read time: 8 minutes

Let's talk about one of the trickiest parts of planning a proposal - figuring out her ring size without ruining the surprise! One of our clients actually told us, "Hopefully she gets drunk this week, and I'll quickly slip on a measuring tape" - points for creativity, but we've got some better ideas for you!

This guide will share our tried-and-true tricks for sneakily getting her ring size right, with real stories from those who've successfully pulled it off.

Why Ring Size Matters

Before we jump into spy mode, here's why getting her size right is actually worth the effort:

1. The moment: Nothing beats that perfect moment when the ring slides on just right
2. Protection: A too-loose ring might fall off (nightmare!), while too-tight isn't comfortable
3. Immediate wear: She'll want to show it off right away, not wait for resizing
4. Design integrity: Some gorgeous details can be tricky to preserve if major resizing is needed

Method 1: Borrow an Existing Ring

This is our #1 recommended approach (and honestly, the one that works best):

1. Find the right ring: Look for one she wears on her ring finger. No ring on that finger? A middle finger ring is usually 1 size larger than what she needs.
2. Know which finger it's for: Different fingers = different sizes, so make sure you know which finger she wears this ring on.
3. Timing is everything: Wait for your moment - when she's in the shower or hitting the gym (pro tip: she shouldn't be wearing jewellery during workouts anyway!).
4. Use the Ring Sizer app: We love the Ring Sizer by Jason Withers app (grab it on the App Store). Just place her ring on your phone screen and line up the inner circle with the app. Super easy and surprisingly accurate!
5. Return mission: Get that ring back before she notices it's missing!

Method 2: Enlist an Accomplice

Sometimes you need a partner in crime:

1. Choose your spy wisely: Her sister, mom, or best friend who can keep a secret is perfect. They usually know her style preferences too, bonus!
2. Create a believable cover: "Hey, I'm thinking of getting Katie some jewellery for her birthday, but I have no idea what size she wears. Could you help?" Or they could suggest going jewellery shopping "just for fun."
3. Be super specific: Make sure your accomplice knows exactly what information you need. Ring finger, left hand, actual size (not just "small" or "she has tiny fingers").

What If You Get It Wrong?

Look, even with all these sneaky tactics, sometimes the size isn't perfect. Don't stress!

1. Go slightly bigger: If you're really unsure, err on the larger side. A too-small ring won't go on at all (awkward!), but slightly loose can still work for the proposal moment.
2. Free resizing at Taels: Here's the good news - we offer free resizing for all custom-designed engagement rings within 2 sizes up or down.

Final Thoughts

Remember, while getting the size right makes for a smooth proposal, it's not what she'll remember years from now. She'll remember your face, your words, and the feeling of that moment - not whether the ring needed a slight adjustment afterward.

The fact that you're reading this article shows you care about getting things right, and that thoughtfulness is what really matters.
