Make Your Own Ring Sizer

What you'll need:   

  • Printer & paper    
  • String, yarn, floss, or a thin strip of paper    
  • Pen or marker    
  • Ruler  

Steps:   

1. Cut a piece of string, yarn, floss, or thin strip of paper to at least three inches long.   

2. Wrap one end of the string around the base of the intended finger.

3. Using a pen or marker, mark where the end of the string overlaps with the rest.

4. Lay the string flat and use a ruler to measure the length between the end and your mark in millimeters.

5. Use the Ring Size Conversion Chart to match the millimeter length to the corresponding ring size.
