Finding the perfect fit for a ring can be tricky, but with the right measurements, you can ensure a comfortable and accurate size. Here's how to determine your ring size:

1. If you have an existing ring, measure its diameter (in mm). Use the ring sizing chart to find the corresponding size.

2. If you don't have a ring to measure, you can measure your finger directly. Cut a strip of paper or string about 3/4th inch wide and wrap it around the base of your finger. Mark the point of overlap and measure the length between the end and the marked point.

3. Compare the measured length to the ring size chart to determine your ring size.

4. Consider both comfort and style. If your knuckles are larger, measure both the knuckle and the base of your finger and take the average of these two measurements. This ensures a comfortable fit over the knuckle without being too loose on your finger.
