How to Measure Your Ring Size at Home
- Wrap a strip of paper or string around the base of your finger.
- Mark the point where the ends meet.
- Measure the length (in millimeters) with a ruler — this is your finger circumference.
- For example:
If your finger circumference is 55 mm, your ring size will be 55 , which corresponds to a US size 7.
Tip: Measure your finger at the end of the day, when it's at its largest. Avoid measuring when your hands are cold.
