Two ways to measure for a ring

1. Measure the circumference of your finger.

Materials needed: flexible measuring tape, string or thin strip of paper, and a ruler.

Choose the finger where you’ll wear your Stone & Shank ring.

  1. Cut a piece of string, floss, yarn, or thin strip of paper at least three inches long.
  2. Wrap it gently around the base of your finger.
  3. Mark the point where the end overlaps.
  4. Lay it flat and measure the length in millimeters using a ruler.

2. Measure Your Ring’s Diameter

To find the perfect fit, use a ring that already fits well along with a ruler or measuring tape.

Step 1: Place the ring on a ruler and measure the shortest inside distance from one inner edge to the other.

Step 2: Use the size chart below to match the measured diameter to the correct US ring size.

This method is ideal when choosing a surprise gift and you don’t want to ask for their ring size.
