How To Size a Ring?

Using a measuring tape is the best and most accurate method to determine your ring size.

For the best results, make sure to give enough space to accommodate your knuckle. Keep in mind that your fingers vary in size during the day depending on several factors, like temperature and humidity. Therefore, it is recommended to measure your finger at the end of the day, when it is likely the largest.

Also, the same finger might differ in ring size for your left and right hand, make sure to measure the finger that you are planning to wear the ring on.

Follow the three simple steps below to measure your ring size using a cord or measuring tape:

Step 1: To measure, simply place the cord (or the measuring tape) around your finger tightly. The ends of the cord should be marked.

Step 2: By using a ruler you can then measure the marked cord and get your ring size in circumference.

Step 3: To find the ring size, match your finger circumference with the European sizing in the second column of the below size chart, and map it to the DIΛMÍND sizing in the first column:
