How to Measure Your Ring Size

Using a Ruler:

1. Cut a strip of paper about 1 cm wide and long enough to wrap around your finger.
2. Wrap the strip of paper around the base of your finger where you'd like your ring to sit. Tip: Ensure the paper is snug but not too tight for an accurate measurement.
3. Mark the point where the paper overlaps with a pen or pencil.
4. Lay the paper flat and measure the length from the start to the marked point using a ruler. Record the measurement in millimeters (mm).
5. Use the chart below to find the corresponding ring size based on your measurement.
