Ring Size

💎 Find Your Ring Size in 3 Simple Steps

Step 1: Measure Your Finger

Option A: Using a string or paper strip

  1. Cut a thin strip of paper (about 10–15 cm long) or use a piece of string.

  2. Wrap it snugly around the base of the finger you’ll wear the ring on.

  3. Mark the point where the ends meet.

  4. Lay the strip flat and measure the length (in millimeters) with a ruler.

  5. This is your finger circumference.

Option B: Using an existing ring

  1. Choose a ring that fits the same finger perfectly.

  2. Measure the inside diameter of the ring in millimeters (mm).

  3. Use the chart below to find your ring size.

Step 3: Check Your Fit

  • Your ring should fit snugly but comfortably — it should slide over the knuckle with a little resistance and sit securely.

  • Measure at the end of the day when your fingers are warm (fingers shrink slightly when cold).

  • Avoid measuring after exercise or in extreme heat.

Pro Tips

  • If you’re between sizes, choose the larger size — it’s easier to resize down than up.

  • For wide bands, go half a size larger for comfort.

  • Remember: both hands can differ — measure the exact finger you’ll wear it on.
