Finding the perfect fit is essential for both comfort and confidence. Use the guide below to determine your ideal ring size before making your purchase.
❖ Method 1: Measure an Existing Ring
-
Choose a ring that fits the desired finger
-
Measure the inner diameter of the ring in millimetres (mm)
-
Match it to the chart below
| Inner Diameter (mm) | LYNN ÉTOILE Size | European Size |
|---|---|---|
| 15.3 mm | 4.5 | 48 |
| 15.7 mm | 5 | 49 |
| 16.1 mm | 5.5 | 50 |
| 16.5 mm | 6 | 52 |
| 16.9 mm | 6.5 | 53 |
| 17.3 mm | 7 | 54 |
| 17.7 mm | 7.5 | 55 |
| 18.1 mm | 8 | 57 |
| 18.5 mm | 8.5 | 58 |
❖ Method 2: Measure Your Finger
-
Cut a thin strip of paper or use a piece of string
-
Wrap it very snugly around the base of your finger — it should feel tight but not uncomfortable. Loose wrapping will result in an inaccurate size
-
Mark where the ends meet and measure the length in millimetres
-
Match your measurement to the chart below
| Finger Circumference (mm) | LYNN ÉTOILE Size | European Size |
|---|---|---|
| 48 mm | 4.5 | 48 |
| 49 mm | 5 | 49 |
| 50 mm | 5.5 | 50 |
| 52 mm | 6 | 52 |
| 53 mm | 6.5 | 53 |
| 54 mm | 7 | 54 |
| 55 mm | 7.5 | 55 |
| 57 mm | 8 | 57 |
| 58 mm | 8.5 | 58 |
✧ Sizing Tips
-
Measure your finger at the end of the day when it’s warm for the most accurate result
-
Avoid measuring when your fingers are cold, as they may appear smaller
-
If you're between sizes, we recommend going up half a size for comfort
