If you already have a ring that fits the finger you want to measure, you can use it as a reference. Choose a ring that you already wear comfortably on the same finger you want to measure. Make sure it fits well, not too loose or tight.

Place the ring flat on a piece of paper and trace the inner circle. Use a ruler to measure the diameter of the traced circle in millimeters. Use a ring size chart to find the size that matches your measurement. For example:

  • US size 6 = 16.5 mm
  • US size 7 = 17.3 mm
  • US size 8 = 18.1 mm
  • US size 9 = 18.9 mm

2. Use a String or Paper Strip

Using a non-stretchable string, ribbon, thread, or thin paper strip to measure ring size is a simple and effective method. This method can give you a pretty accurate estimate of your ring size.

Take the string or paper strip and wrap it around the base of the ring finger, close to the knuckle you want to measure. Make sure it’s snug, but not too tight. Use a pen or marker to mark the point where the string or paper overlaps to form a complete circle.

Lay the string or paper strip flat and use a ruler to measure the length from the end to the mark you made. This will give you the circumference of your finger. Use a ring size chart to match the circumference measurement to the corresponding ring size. Most charts will show you the corresponding ring size for the measured finger circumference.

3. Printable Ring Sizer

Take the sizer and wrap it around the base of the finger that you want to measure; make sure it’s snug but not too tight. Once you’ve wrapped the sizer around your finger, look at where the end of the strip meets the marked line. This will give you the ring size that corresponds to your finger’s circumference.

If you’re unsure about the fit, try measuring your finger a couple of times or using the sizer on different fingers to ensure consistency.

4. Compare with a Friend’s/Relative’s Ring

If you don’t have access to a ring sizer, comparing your finger size with a friend’s ring can be a good method for finding your ring size. If you have a friend or family member who knows their ring size, you can try on their ring to see if it fits.
