Ring Size Chart & Guidance

Finding the Right Ring

A ring is more than a question of size. The way it sits, moves and feels on the finger is part of the experience.

From delicate bands to statement silhouettes, different designs can call for different considerations. Here is our guide to choosing a fit that feels naturally right.

Method 01 — Measure your finger

Method 02 — Measure a ring you already own

If your measurement falls between two sizes, we recommend choosing the larger size for greater comfort.

Method 01

Measure Your Finger

Step 01
Wrap a narrow strip of paper or thread around the finger on which you intend to wear the ring. Keep it comfortable, allowing enough room for it to pass over the knuckle.

Step 02
Mark the point where the paper or thread meets, then measure the length against a ruler.

This measurement represents your finger circumference. Match it with our ring size chart to find the corresponding size.

If your measurement falls between two sizes, we recommend choosing the larger size for greater comfort.

Method 02

Measure a Ring You Already Own

Choose a ring that fits the intended finger comfortably.

Place it on a flat surface and measure the inside diameter across the widest point of the ring using a ruler.

Compare this measurement with our ring size chart to determine your closest size.

For the most accurate result, measure carefully, as even a small difference can affect the fit.

Before You Choose Your Size

A Few Details to Consider

Your ring size can vary slightly depending on the finger, hand and design of the ring.

The fingers on your dominant hand may measure differently from those on your other hand. Temperature can also affect how a ring feels, so we recommend taking your measurement when your hands are at their usual temperature.

For the most accurate result, measure the specific finger and hand on which you intend to wear the ring.
