Ring Size Guide

1. The String Method

  • I recently measured my ring finger at home using this method, and the process was much easier than I expected. While I had a vague recollection of my ring size (I remembered it being either a 7 or an 8 ) I wasn’t completely sure, even though I’d been told by a jeweller more than once. (File this under facts I easily forget.) Thankfully, I was able to determine my ring size using just four simple things I already had at home.

What You’ll Need:

  • A piece of paper, string, or floss. (I used a piece of scrap paper.)
  • Scissors
  • A tape measure or ruler
  • Pen or pencil

How to Do It:

Step 1: Cut a thin and long strip of paper or a piece of floss.

Step 2: Wrap the paper around your ring finger just below the knuckle. Measure this area carefully, as the ring should comfortably fit over this part of your finger.

Step 3: Once the paper feels snug, mark where the two ends meet on the inside of your finger using a pen. (See photo above.) If you are using string or floss, cut it at this point instead. Be careful not to wrap it too tightly — aim for a comfortable fit rather than a tight one.

Step 4: Flatten the strip of paper or string and measure the length from the mark to the end using millimeters or inches.

Step 5: Match your measurement with the corresponding standard ring size chart below. Most ring sizes are measured in millimeters (mm) and typically range from size 5 to 13.
