How to Measure Your Ring Size

To ensure the best fit, follow these simple steps to measure your ring size:

  2. Mark where the string or paper overlaps and measure the length with a ruler.
  3. Compare the measurement to the circumference values in the table above to find your size.

If you're unsure about your ring size, it's always best to visit a jeweler to get an accurate measurement.
