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

  1. Choose a ring that fits the desired finger

  2. Measure the inner diameter of the ring in millimetres (mm)

  3. 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

  1. Cut a thin strip of paper or use a piece of string

  2. 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

  3. Mark where the ends meet and measure the length in millimetres

  4. 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
