Ring size measurement

Method 1: Using an Existing Ring
If you already have a ring that fits the desired finger well, you can use it to determine your size:

  1. Place the ring on a ruler or measuring tape marked in millimeters (mm).
  2. Measure the inner diameter—the distance across the ring's opening where it touches your finger.
  3. Refer to our Ring Size Chart to match the diameter to the correct ring size


Method 2: Using Paper or String
No ring? No problem. Try this easy method:

  1. Cut a strip of paper or a piece of string about 10 cm long.
  2. Wrap it around the base of your finger where you plan to wear the ring. It should be snug but comfortable.
  3. Mark the point where the end of the paper or string overlaps.
  4. Lay it flat and measure the distance from the edge to the mark using a ruler in millimeters.
  5. This measurement is the circumference of your finger. Use the Ring Size Chart to find your corresponding size.
