How to Find Her Ring Size Secretly: EU and US Ring Sizes Explained
The most reliable way to find her ring size secretly is to borrow a ring she already wears on the right finger and have a jeweller measure it. If that is not possible, a tracing of one of her rings, a quiet word with a close friend or a carefully measured strip of paper will get you close. And if you are slightly off, our engagement rings in Lebanon include one free resize within two sizes, so a near guess is perfectly fine.
Why ring size matters for an engagement ring
A ring that is too tight is uncomfortable from the first evening. One that is too loose turns on the finger, so the centre stone drifts to the side, and it can slip off. Getting close the first time means she can wear her ring straight away, the night you propose.
At Vucceli, every 18K gold engagement ring is made to order in our own workshop in Lebanon, in ring sizes EU 47 to 57, and is ready within 30 working days. Because the ring is made for her, the size is part of the order from the very start, which is why a little careful detective work is worth it.
Five discreet ways to find her ring size
1. Borrow a ring she already wears
This is the most dependable method. Choose a ring she wears on her left ring finger if you can. A ring from the same finger on her right hand also works as a starting point, though the dominant hand is often slightly larger. Take it at a moment she will not miss it, bring it to us, and it can be measured in a minute on a ring mandrel.
2. Trace or press one of her rings
If the ring cannot leave the house, place it on a sheet of paper and trace the inside of the circle with a sharp pencil, or press it gently into a bar of soap or a little modelling clay. Photograph the result next to a ruler. A jeweller can read the inner diameter from a clean tracing.
3. Ask a friend or family member
In Lebanon, someone always knows. A sister, her mother or her closest friend may already know her size, or can suggest trying on rings together while shopping. Choose someone who can keep the secret until the big day.
4. Measure while she sleeps
Wrap a thin strip of paper or a non-stretch thread around the base of her ring finger, mark where it meets and measure the length in millimetres. This gives the circumference, and conveniently the EU size is simply the inside circumference in millimetres. It is the least precise method, because fingers change through the day and thread can stretch, so treat the result as a guide.
5. Compare with your own fingers
Slip one of her rings onto your own fingers and note exactly where it stops, for example just above the middle knuckle of your little finger. At the showroom we can match that point to a size.
EU and US ring sizes: a quick conversion
Lebanon and most of Europe use EU sizes, while many of our clients in the diaspora know their size in US numbers. Here is how our range compares. Conversions are approximate, so if you find yourself between two sizes, choose the larger one.
| EU size | US size | Inside diameter |
|---|---|---|
| 47 | 4 | 14.9 mm |
| 49 | 5 | 15.7 mm |
| 52 | 6 | 16.5 mm |
| 54 | 7 | 17.3 mm |
| 57 | 8 | 18.1 mm |
Tips for a more accurate measurement
- Measure at the end of the day, when fingers are at their fullest.
- Heat, salty food and travel can make fingers swell a little, worth remembering for a summer proposal in Lebanon.
- A wider band feels tighter than a slender one in the same size, so tell us which style you have chosen.
- A ring that fits well slides over the knuckle with slight resistance and does not spin freely.
What if the size is not quite right?
Do not let ring size delay the proposal. Every Vucceli engagement ring includes one free resize within two sizes, so if your estimate is slightly off, she can visit the showroom afterwards and we will adjust it. To design something entirely around her, our bespoke engagement ring service lets us plan the size together from the start. You will find more practical answers on our FAQ page.
Proposing from abroad? Clients in the diaspora often send us a photo of a tracing or the measurements, and we deliver by DHL internationally in about a week, fully insured, or by Aramex within Lebanon in about 3 days.
Choosing the ring itself
Once the size is settled, the enjoyable part begins. Browse our engagement rings in round, oval and pear shapes. Each centre stone is an IGI certified lab grown diamond, colour E, clarity VVS2, with an excellent cut and no fluorescence, set in solid 18K yellow, white or rose gold. Like all our diamond jewellery, it is Proudly Crafted in Lebanon, and lab grown diamonds are real diamonds, chemically and physically the same as mined ones.
Frequently asked questions
How accurate is measuring a ring size with string?
It is only a rough guide. String stretches and is hard to read precisely, so use it when you cannot borrow or trace a ring, and lean towards the larger size.
Can an engagement ring be resized after the proposal?
Yes. Vucceli includes one free resize within two sizes, so a small difference is easily corrected.
