Waterproof OPHELIA Initial Signet Ring

What You’ll Need:

• A strip of paper or non-stretchy string
• A pen or pencil
• A ruler (millimeters preferred)

Steps:

1. Wrap the paper, string or floss around the base of the finger you’ll wear the ring on.
2. Mark the point where the paper or string overlaps to form a complete circle.
3. Measure the length from the start to the mark using your ruler — this gives you the circumference of your finger.
4. Compare your measurement to our ring size conversion chart to find your US ring size.

Tips:

• Measure at the end of the day when your fingers are at their largest.
• Ensure the paper or string isn’t too tight — it should slide over your knuckle comfortably.
• For accuracy, repeat the process 2–3 times.

If you have a ring that already fits, check the inside for any size markings or use a tape measure or ruler to check the inside diameter of the ring - then use our conversion chart below to find your size.
