Ring Size Guide
Getting the right fit is easy. Use one of the two methods below to find your size at home — no special tools needed.
Method 1 · Measure with string or paper
Wrap a strip of paper or string around your finger
Choose the finger you'll wear the ring on. Wrap it snugly around the base — not too tight, not loose.
Mark where it overlaps
Use a pen to mark the point where the end meets the strip, forming a full circle.
Measure the length in millimetres
Lay the strip flat against a ruler and measure up to your mark. This is your finger's circumference.
Match it to the chart below
Find the closest circumference in the table to get your size. If you're between sizes, choose the larger one.
Method 2 · Use a ring you already own
Pick a ring that fits the right finger
Choose one that sits comfortably on the finger you're buying for.
Measure its inner diameter
Place the ring on a ruler and measure straight across the inside, edge to edge, in millimetres.
Match the diameter to the chart
Compare your measurement to the “Inner diameter” column below to find your size.

Tips for an accurate fit
- Measure at the end of the day, when fingers are at their largest.
- Avoid measuring when your hands are cold — fingers shrink slightly.
- Measure 2–3 times to be sure, and take the average.
- For wider bands, consider going up half a size for comfort.
