Measuring finger circumference
Tips: Ring size is determined based on the close-fitting measurement. Just choose the one that is closest to your actual finger circumference so it won’t be too tight when worn.
For example: The finger circumference is 55mm (5.5cm), the closest ring size is US 7
Method 1 - Use a tape measure
Wrap the tape measure around the base of your finger, keeping it snug and taut. This is the circumference of your finger. Round up to the nearest millimeter.
Method 2 - Using string or paper
1. Wrap the string around the bottom of your finger and pull it snug.
2. Mark the location with a pen.
3. After straightening the string, measure the length of the string. This is the circumference of your finger. Round it up to the nearest whole millimeter.
Method 3 - Measuring the diameter of your ring
Tips: It is best to measure a round ring. If it is not round, please measure the shortest diameter.
