How to measure

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 Holts & Gems ring size.
