Measure Your Finger

Step One

Wrap a string, piece of paper, or fabric around the base of the finger.

Step Two

Mark the point where it overlaps to form a full circle.

Step Three

Lay it flat and measure the length in millimetres.

Step Four

You'll get the ring size by circumference

How Should Your Ring Fit?

Your ring should feel comfortably secure on your finger without feeling too tight. It should slide over your knuckle with slight resistance and sit comfortably at the base of your finger without pinching or moving around too freely.

What If You’re Between Sizes?

If your measurement falls between two ring sizes, we generally recommend choosing the larger size for a more comfortable fit. Keep in mind that finger size can change slightly with temperature and time of day, so measuring more than once can help you choose with confidence.
