Measure Your Ring Size by Using an Existing Ring

1
Place a millimetre (mm) ruler on a flat surface. Keep it straight, clear, and easy to read.
2
Place the ring on the ruler so it fits properly. Carefully align it with the millimetre marks.
3
Measure the widest inner part of the ring. Read the diameter from one inside edge to another.
4
Write down the inside diameter in millimetres. Match it to the ring size chart below for size.

Measure Your Ring Size by Using a Paper Strip

1
Cut a thin strip of paper, clean and even. Make sure it is long enough to wrap.
2
Wrap it around the base of your finger. Mark the point where the paper overlaps.
3
Place the strip flat on a millimetre (mm) ruler. Measure from 0 to the marked point.
4
Now you have your finger circumference in mm. Use the ring size chart below to find your size.

Frequently Asked Questions

How can I measure my ring size at home?

Wrap a strip of paper or a piece of string around the base of your finger and mark the point where it overlaps. Measure that length against a millimetre ruler, then match it to the circumference column in the chart above. Measure at the end of the day, when your finger is typically slightly larger.

Can I order using my local size?

Yes. You can order in your local sizing — use the conversion chart above to find the equivalent, or contact our customer service team and we will help you convert it.
