Measure your finger

What You'll Need:

A piece of string or a thin strip of paper

A ruler

A pen or marker

Steps:

1. Cut a Thin Strip of Paper or String: It should be about 3 inches long and 1/4 inch wide. If you're using string, make sure it doesn’t stretch.
2. Wrap Around Your Finger: Wrap the strip of paper or string around the base of the intended finger. Make sure it's snug but not too tight; you should be able to slide it over your knuckle comfortably.
3. Mark the Spot: With a pen or marker, mark where the end of the strip or string meets around the finger.
4. Measure the Length: Lay the strip or string flat next to a ruler and measure the distance to the mark in millimeters.
5. Find Your Ring Size: Use a ring size chart available online to convert the measured length to a ring size. Most charts will list sizes in millimeters, correlating to standard ring sizes.
