How do you measure a man's ring size?

  • Cut a thin strip of paper.
  • Wrap the paper around your finger. Make sure the paper is below the joint of your finger and close to your knuckle.
  • Mark the spot where the paper meets and measure the distance with your ruler.
  • Use the following chart to determine your ring size. Rings also come in half sizes. These measurements will fall somewhere in between the whole sizes.
