Ring Size
💎 Find Your Ring Size in 3 Simple Steps
Step 1: Measure Your Finger
Option A: Using a string or paper strip
-
Cut a thin strip of paper (about 10–15 cm long) or use a piece of string.
-
Wrap it snugly around the base of the finger you’ll wear the ring on.
-
Mark the point where the ends meet.
-
Lay the strip flat and measure the length (in millimeters) with a ruler.
-
This is your finger circumference.
Option B: Using an existing ring
-
Choose a ring that fits the same finger perfectly.
-
Measure the inside diameter of the ring in millimeters (mm).
-
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.
