Ensure your chosen size allows the ring to slide comfortably along the entire length of your finger, including the knuckle. Remember that your hands differ slightly in finger circumference —a ring that fits perfectly on one hand may feel more tight or loose on the other. Avoid measuring when your hands are too warm or too cold, as temperature can cause slight swelling or shrinkage.

1. Wrap a length of string or ribbon around the base of your finger.
2. Mark the point where the string or ribbon overlaps.
3. Lay it flat and measure the length in millimeters with a ruler.
4. Compare your measurement to the size chart below to determine your ring size.

If you find yourself between two sizes, choose the larger one for greater comfort. Keep mind that stone settings do not change with size.
