Select an existing ring that fits the desired finger

Measure the internal diameter of the ring (in mm)
Use the below chart to determine your ring size

Our ring sizes all use standard US measurements

  • Make sure your fingers are at a "normal" size when you measure them. Fingers can shrink in cold weather, and they swell after you've had alcohol, salt, or after you've exercised. 
  • If your knuckle is particularly big, you may want to choose a bigger ring size so that the ring can fit over the knuckle.
  • What's a good fit? Your ring should slip on easily but be snug around your finger.
  • Keep in mind that your ring size differs between the left and right hands, with the fingers on the dominant hand typically being larger.


If you don't have an existing ring to measure against, you can easily determine your desired ring size finger with some common household items. You will need a piece of thin string, dental floss or a strip of paper, a pen, and a measuring tape or ruler.

To find your ring size, simply follow these instructions:
Wrap the intended finger snugly with a piece of string/floss or strip of paper.
Use a pen to mark where the string/floss/paper meets around your finger
Straighten out the string/floss/paper and measure it against a ruler in millimeters
Check the ring size chart in the "Finger Circumference (mm)" to find your correct size.

Please note that this is a rough guide and that we do suggest you get your ring sized at your local jeweller.


Does Band Thickness Affect Ring Size?
Yes, you may need slightly different ring sizes for bands of different thicknesses. The reason is that thicker bands cover more surface area, and they need to be appropriately sized to slide over the knuckle and to comfortably fit the entire area of the finger that it will rest on. Thin rings are a bit easier to wiggle over the knuckle and can be situated on the part of the base that best suits the size.
