How to Measure Your Finger for a Ring

Wrap a thin piece of string or sewing thread around the finger where you plan to wear your ring. Make sure it fits comfortably without being too tight.

Mark the point where the ends of the string meet using a pen, or carefully cut the string at that point.

Lay the string flat on a table and use a ruler to measure its length in millimeters.

Use our Ring Size Chart to convert your measurement into the correct ring size.

Helpful Tip: For the most accurate results, measure your finger when your hands are warm, as cold temperatures can cause your fingers to shrink slightly.

How to Measure an Existing Ring

If you're purchasing a ring as a surprise gift, you can discreetly borrow a ring that the recipient already wears on the same finger.

Place the ring on a piece of paper and carefully trace the inside edge with a pen.

Using a ruler, measure the diameter of the circle in millimeters, from one inside edge to the opposite inside edge.

Use our Ring Size Chart to find the corresponding ring size.

Need a Size Adjustment?

If your finished ring doesn't fit perfectly, we may be able to resize it at our workshop, depending on the ring's design.
