How to give a ring without knowing the size?
Adjustable ring or discreet sizing: our methods for providing a ring that fits the first time, even without knowing the size.
When giving a ring without knowing the size, the easiest option is to choose an adjustable ring: it fits the finger and there is nothing to measure. If you prefer a closed ring, you can discreetly find the size by measuring a ring the person already wears. Here are the two methods, and our tips for choosing the right model.
The essentials in brief
An adjustable ring eliminates the risk of error: all Bamàs rings are adjustable, and those shown here cost from €29.90 to €34. For a closed ring, measure the inner diameter of a ring she wears: the French size corresponds to the finger circumference in millimeters. Returns and exchanges are possible within 30 days of receipt.
Why give an adjustable ring?
An adjustable ring is open: it can be tightened or slightly widened by hand to fit the finger. It is the safest solution when you want to make a surprise, and this is the case for all Bamàs rings.
- No measurements needed: no need to borrow a ring in secret.
- It changes fingers: simply readjust it to wear it on another finger.
- It adapts to changes: fingers swell slightly in the heat and shrink in the cold.
- It can be shared: an adjustable ring can go from one sister to another.

If you prefer a closed ring, or if you simply want to know where you stand, here are the most reliable methods:
- Borrow a ring she wears on the same finger, then measure its inner diameter with a ruler, from one inner edge to the other. You can also trace the inside of the ring on a piece of paper and put it back immediately.
- Slide this ring onto one of your fingers and mark the spot where it stops with a pen: you will then measure your finger at that point.
- Ask a close friend: a friend or sister often knows the size, or can ask without raising suspicion.
- Check the hand: the size of the same finger can vary slightly between the right and left hand.
To go from diameter to size, multiply the inner diameter by 3.14: you get the finger circumference in millimeters, which corresponds to the French size.
| Inner diameter | Finger circumference | French size |
|---|---|---|
| 15.9 mm | 50 mm | 50 |
| 16.6 mm | 52 mm | 52 |
| 17.2 mm | 54 mm | 54 |
| 17.8 mm | 56 mm | 56 |
| 18.5 mm | 58 mm | 58 |
Between two sizes, always choose the larger one: a ring should pass the joint with slight resistance, without forcing.

How to adjust an adjustable ring without damaging it?
- Slide the ring onto the chosen finger.
- To tighten it, press gently and evenly on both sides of the opening. To widen it, spread them very slightly with your fingers.
- Adjust it all at once, in small steps, without tools.
- Avoid opening and closing it too often: like all metal, steel wears out if bent repeatedly.
Our advice: in case of doubt, choose a fine ring. It can be worn on almost every finger and easily stacked with the ones you already have. Slide the ring into its linen pouch with a little note: it comes with a card, ready to give.
“I never take off my rings, it's exactly what I was looking for, thank you!”

Frequently asked questions
How to convert a diameter into a ring size?
Multiply the inner diameter in millimeters by 3.14. The result is the finger circumference in millimeters, which corresponds to the French size: a diameter of 17.2 mm gives a size 54.
Does an adjustable ring fit all fingers?
It fits within a certain range of sizes, which allows it to be worn on different fingers. A fine ring, without a large stone, is the easiest to adapt.
Does an adjustable ring stay well on the finger?
Yes, if it is well adjusted: it should pass the joint with slight resistance and not spin on itself.
Can you give a ring as a friendship gift?
Of course. A fine ring or a ring with a colored stone is a simple gift, worn every day, without the strong symbol of an engagement ring.
