How to Measure Your Ring Size Accurately

Method 1: Measure an Existing Ring

1. Take a ring that fits well and place it on a ruler
2. Measure the inner diameter in millimeters
3. Match to our size chart below

Method 2: Paper Strip Method (most accurate)

1. Cut a 10cm strip of paper or use floss
2. Wrap snugly around your finger's base
3. Mark where it overlaps and measure length in mm
4. Compare to circumference in our chart

Pro Tip: Measure at night when fingers are slightly larger, and avoid cold temperatures which shrink fingers temporarily.
