How to measure your ring size

  • Take a well-fitting ring and measure the diameter of the inside of your ring. This is your ring size.
  • Use a flexible measuring tape to measure the circumference of your finger. If you don't have a measuring tape, use a piece of paper or string, no thicker than 0.5 mm, and then measure the length of the paper / string with a ruler. This is the circumference of your finger

Tips to measure your ring size

  • Do not measure your fingers when they are cold. Then your fingers are smaller.
  • It is also not convenient to measure your finger on a very hot summer day
  • If your knuckles are very large, it is best to choose a larger size..
  • Measure your fingers at the end of the day.
  • Please note the ring size of each hand can be different.
  • If the ring has a stone, it is important to measure the size as exact as possible otherwise the ring will turn.
