Ring Size Chart & Guide

Finding the perfect fit should feel effortless. Use our simple guide below to determine your ideal ring size at home.

Before You Measure

For the most accurate result, we recommend:

• Measure your finger at the end of the day, when fingers are at their natural size.
• Avoid measuring when your hands are cold, as fingers tend to be smaller.
• If your measurement falls between two sizes, choose the larger size for a more comfortable fit.
• Consider the ring design — wider bands generally fit more snugly than delicate styles.

Method 1 — Measure Your Finger

A quick and easy way to find your ring size.

Step 1

Wrap a thin strip of paper or a flexible measuring tape around the base of your finger.

Step 2

Mark the point where the ends meet.

Step 3

Lay the strip flat and measure the length in millimetres (mm).

Step 4

Use the size chart below to match your measurement to the corresponding ring size.

Tip: Ensure the strip sits comfortably — secure enough not to slide off, but loose enough to move over the knuckle.

Method 2 — Measure a Ring You Already Own

If you already have a ring that fits comfortably:

Step 1

Choose a ring that fits the intended finger.

Step 2

Measure the inside diameter of the ring (excluding the band thickness).

Step 3

Match the inside diameter to the ring size chart.

For best accuracy, place the ring on a flat surface while measuring.

Between Sizes?

If your measurement falls between two sizes, we generally recommend choosing the larger size for a more comfortable everyday fit.

For wider bands (3mm+), consider sizing up by half a size.
