How to Find the Perfect Fit (Without Ruining the Surprise)

💍 Why Ring Size Matters

Getting the right ring size is one of the most important—and often overlooked—parts of the engagement ring process. Whether you’re planning a surprise proposal or shopping together, the goal is the same:

a comfortable, secure fit that’s perfect from the moment it slips on.

You Don’t Need to get it Perfect First Time

Most rings can be resized easily, but this guide will help you get as close as possible, with tips for stealth sizing, international conversions, and professional adjustments.

🔍 How to Find Out Her Ring Size (Without Asking)

Planning a surprise proposal? Here are discreet ways to uncover her ring size:

🕵️‍♂️ Use a Ring She Already Wears

  • Borrow a ring from her jewellery box
  • Trace the inside on paper, or press it into a bar of soap
  • Bring it to us—we can measure it accurately
  • Important: Make sure it’s worn on her ring finger (left hand!)

💬 Ask a Trusted Insider

  • Enlist help from a close friend, sister, or mum
  • They may already know, or can ask without suspicion
  • Be sure they can keep a secret!

💡 Compare Fingers

  • If your hands are similar in size, try wearing one of her rings
  • Note how far it goes and which of your fingers it fits

💑 Shopping Together? Make It Easy

If you’re choosing the ring as a couple:

  • Come in-store for a professional ring sizing (quick & accurate)
  • Use a ring sizing tool at home (we can provide one)
  • Try on sample rings in your preferred style to see how different band widths feel

🇮🇪 Understanding Irish Ring Sizes

In Ireland and the UK, engagement ring sizes are measured using the alphabetic system (A–Z). Below is a guide comparing UK/IE sizes with European (mm) and US ring sizes, as well as helpful notes on fit.

UK/IE Size EU Size (Approx.) US Size Fit Notes
F 44.5 3 Very petite – common in pinky rings
G 45.5 3.5 Petite – smaller hands or pinky rings
H 46.5 4 Slim fingers – smaller-framed wearers
I 47.5 4.5 Still petite but more common
J 48.5 5 Starting point for small engagement rings
K 50 5.5 Popular petite size
L 51.5 6 Common for smaller-to-average hands
M 52.5 6.5 Most popular women’s ring size
N 54 7 Average-to-fuller fingers
O 55 7.5 Also common, especially with wider bands
P 56.5 8 Slightly broader fingers
Q 57.5 8.5 Larger hands or comfort-fit styles
R 59 9 Great for wider knuckles
S 60.25 9.5 On request
T+ 61.5 10 On request

💡 M is the most commonly worn size among women in Ireland, with L and N close behind.

🔄 Can the Ring Be Resized Later?

✅ Most rings can be resized

  • Plain bands: very flexible (+/- 2–3 sizes)
  • Pavé settings or eternity rings: may be limited (half sizes or remakes)
  • Some designs (e.g. with split shanks or tension settings) may need more specialist work

⚠️ Things to Avoid:

  • Guessing wildly—going too small may cause the ring not to fit at all
  • Buying a full eternity ring if unsure of the exact size

💡 We offer free in-store ring sizing and post-proposal resizing services—so there’s no pressure to get it perfect first time.

❄️ Ring Sizing Tips You Might Not Know

  • Fingers shrink in cold weather and swell in heat or after physical activity
  • Try to size when hands are at a comfortable, neutral temperature
  • Wider bands feel tighter—consider going half a size up
  • Thinner bands may feel looser and are often more forgiving

🧠 FAQ – Quick Sizing Questions

Q: What if I guess the wrong size?
No problem! We’ll adjust it after the proposal—resizing is a quick and straightforward process in most cases.

Q: Can you size a ring before it’s set?
Yes—when buying from us, we can size the mount before the diamond is set for a seamless fit.

Q: Can you resize lab-grown or vintage rings?
Yes—though some vintage bands may need extra care. We’ll advise during your consultation.

🏁 Final Thought: A Ring That Fits—and Feels Right

Finding the perfect ring size doesn’t have to be difficult. Whether you’re going for a surprise or choosing together, there are plenty of ways to get it right—or close enough to resize comfortably.

💍 Because the best engagement ring is one that fits the finger, the moment, and the story behind it.
