How to Decide Your Ring Size

It is important to know your exact ring size before buying a ring, especially online. You certainly don't want to receive a ring that doesn't fit your finger.

The good news is you can easily measure your ring size at home with very basic materials. All you need are a strip of paper, a pen and a ruler.

  1. Wrap the paper around the finger to be sized. Make sure the paper is below the joint of your finger and close to your knuckle.
  2. Mark the spot where the paper strip meets.
  3. Measure the distance with a ruler and then you get the circumference of your finger.

Then you can find your suitable ring size in the chart below.
