How to Measure your Ring Size

Determining someone's correct ring size, by using a properly fitting ring or by measuring the finger in question, is important to ensure a perfectly fitted ring whether for yourself or a someone else. Below you will find two easy methods to measure ring size. However, if at any point you feel unsure, please feel free to contact us for further assistance.

Method 1: Measuring a Ring You Already Own
  • Select a ring that properly fits the intended finger
  • Measure the INSIDE diameter of the ring
  • Match the measurement to the conversion chart to the right. If the ring falls between two sizes, we advise you to order the larger of the two sizes.

Please note: Rings with a particularly thick band will feel tighter than those with a thin band. In those cases, we recommend buying a full size larger than your normal ring size.

Method 2: Measuring Your Ring Finger

How to Measure Ring Size

Your ring should fit your finger comfortably; it should be snug enough to stay safely on, but loose enough to slide over your knuckle.

Please note: Your finger size can change throughout the day, so it is a good idea to measure at the end of the day when your fingers are at their largest. Do not measure when your hands are cold; your fingers will be at least half a size smaller.

Step 1:

Cut a piece of string or a ¼ inch wide piece of paper to about 2 inches in length.Wrap the piece of string or paper around the base of your ring finger. Wrap around both the base of your finger and your knuckle if your knuckle is noticeably larger than the base of your finger.

Step 2:

Mark the string or paper at the exact point that it overlaps to make a complete circle around your finger. Do this for where it overlaps on your knuckle as well, if you needed to measure it.

Step 3:

Unroll the string or paper and place it against a ruler with millimeter measurements. The length of your measurement is the circumference of your ring finger. If you needed two marks because of your knuckle, make a new mark exactly between the two and use that mark as your measure. Refer to the ring chart above to get your ring size. 

*Note: Refer to the ring chart above to get your ring size. For example, if the circumference measures 62 mm, your ring size is a 10. Or, if you know your ring size is a 19, then your equivalent ring size is 8 3/4.
