Find Your Ring Size

A perfect fit is the difference between a ring you wear once and a ring you wear for years.

Method 1 — Measure with a strip of paper

The easiest way to find your size at home. All you need is a strip of paper, a pen, and a ruler.

Method 2 — Measure a ring you already own

If you have a ring that fits perfectly on the same finger:

1. Place the ring flat on a table.
2. Measure the inner diameter in millimeters — straight across the inside of the ring, edge to edge.
3. Match the measurement to the chart below.

Tips for the perfect fit

• Measure at the end of the day. Fingers swell slightly as the day goes on — that's when you want the ring to still feel comfortable.
• Warm hands measure best. Cold fingers shrink and can give you a size too small. Avoid measuring right after coming inside on a cool day.
• Your dominant hand is usually larger. Often by half a size. Measure the exact finger you'll wear the ring on.
• Between two sizes? Size up. A ring should slide on past the knuckle and rest snug at the base — never tight.
• For wider bands, go one size up. Wider rings sit tighter than thin bands of the same size.
