Guide to choosing the ring size

Inside diameter

Inside circumference

The chart below provides a useful overview of current measurements of the National Standard System relative to the size of rings, diameter and circumference of the finger in centimeters.

If you do not know the size of your finger, follow the following tips to get it.

  1. Measure the finger.
    Wrap a tape measure or strip of paper around your finger as close to the falange as you can, trying to make it stick to your finger, but comfortably: the right fit must slide on your finger without forcing and, at the same time, should not slip out waving your hand.
    The size of the fingers changes during the day, so it is preferable to take the measurements at the end of the day, avoiding when you wake up in the morning, or after a long physical effort or any other activity that could swell your fingers.
    If your measure oscillates between two sizes, opt for the larger one.
  2. With a pencil marks the point where the ribbon or strip of paper overlaps.
  3. Compare the value you have taken with those shown on the underlying chart.
