Sizing Guide


Here are two methods, for measuring the size of your rings, note that 21grams uses US size:

1.Employ a precision measuring tape - This method offers enhanced accuracy and precise measurements.

2.Utilize a non-elastic strip of paper, ribbon, or string to measure the circumference. Mark the end point with a pen, and then compare the length against a ruler or measuring tool for accurate sizing.


The Hands-on Method

1. Grab a tape measure, length of string or strip of paper. 

2. Wrap it around the finger you’ll wear your ring on, if you’re creating a ring stack, consider where on your finger the ring will sit, and mark the place where it joins.

3. Lay your string or paper strip on a flat surface and use a ruler to measure the length up to the mark. Use the chart above to match the measurement to the closest 21grams ring size.
