How To Measure
- Grab a tape measure, length of string or strip of paper.
- 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.
- 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 ring size.
- Choose a ring that already fits your finger well.
- Measure the interior diameter of the ring in millimeters (mm).
- Use the measurement chart above to match the size of your ring to the closest size in mm.
