How to Measure Your Ring Size in Millimeters
- Gather Your Materials: You’ll need a strip of paper, a pen, and a ruler with millimeter measurements.
- Wrap the Paper: Take the strip of paper and wrap it around the base of your ring finger. Ensure it fits comfortably over the knuckle.
- Mark the Paper: Use the pen to mark the point where the paper overlaps.
- Measure the Length: Unwrap the paper and measure the length from the start to the pen mark using the ruler.
- Find Your Size: Use the chart below to determine your ring size based on your measurement.
