How To Measure Your Ring Size
Method 1: Measure a Ring
Find a ring that fits comfortably on the finger you intend to wear your new ring on.
Measure the internal diameter of the ring, using a ruler or measuring tape. To do so, ensure you are using a ruler with millimetre (mm) measurements, then place your ring on top of the ruler and measure the inside of the circle – in other words, the part that is in contact with your finger.
Use our Ring Size Chart to convert your diameter measurement into the correct ring size.
Method 2: Measure your Finger
Cut a piece of string or paper to a length of around 10 centimetres (cm).
Wrap the paper or string around your finger at the point where the ring should sit. Pull so that the string fits comfortably around your finger - not too tight and not too loose.
Use a pen to mark the point where the end of the string or paper overlaps itself.
Lay the string or paper out against a ruler or tape measure, and measure the length (mm) from its end to the point you have marked with pen, use it to find your size using our Ring Size Chart below.
