Ring Size Chart

If you are between sizes, order a larger size. Make sure your finger is at a normal body temperature (fingers shrink or expand when cold or hot). If your knuckle is much larger than your finger’s base, take two separate measurements and choose a size in between. You want a ring to fit over your knuckle, but not be too loose or it will shift around.

How to size your finger using the string method

  1. Use a thin piece of thread
  2. Wrap the thread around your finger. Make sure the thread is below the joint of your finger and close to your knuckle
  3. Mark the location where both ends of the thread meet and measure the distance with your ruler
  4. Measure your fingers a few times to ensure the sizing is correct
  5. Use the following chart to determine your ring size
