💍 How to Measure Your Ring Size at Home

Option 1: Using a String or Paper Strip

1. Wrap a thin strip of paper or string around the base of your finger.
2. Mark where the end meets the rest of the string or paper.
3. Measure the length in millimeters (mm) using a ruler.
4. Check the size using a ring size chart (example below).

Tip: Measure at the end of the day when your fingers are warm, for the most accurate result.

✅ Tips for Accurate Measuring

• Measure your finger at the end of the day when it’s largest.
• Avoid measuring when hands are cold — fingers shrink slightly.
• Use a ring sizer, or printable sizer, or follow the string method (wrap string, mark it, then measure).
