Ordering a ring online comes down to one measurement. Two ways to take it, and a chart for every sizing system we ship to.

Ring Size

The most reliable method: measure a ring that already fits. Take a ring that fits that finger well, lay it on a flat surface and measure the inside diameter in millimetres from edge to edge. Read that number against the US column below.

If you do not have a ring that fits, wrap a strip of paper or a piece of string around the base of the finger, pull it snug, and mark where it meets. Measure the length in millimetres — that is the inside circumference. Then compare it with the chart.

Other tips

• Measure your finger in warm temperatures, at the end of the day — that is when a finger is at its largest.
• If your knuckle is noticeably wider than the base of your finger, measure both and choose a size between the two.
• On a wide band, go up one size from your measurement for comfort.

How to measure for a bracelet

1. Wrap a soft tape measure, or a strip of paper, around the broadest part of your wrist and note the length. If you use paper, mark it and measure against a ruler.
2. Add an inch (2.5 cm) to that measurement — that is the final bracelet length, with room to tuck two fingers under it.

Notes

• A bracelet is sized right when your wrist measurement plus 2–3 cm sits comfortably.
• Between sizes? Tight wearers should take the smaller size, loose wearers the next size up.
• A new bracelet can feel stiff and tight at first. It softens and becomes more flexible within a few wears.
