Method 1: Measure a Ring (Diameter mm)
- 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

Method 2: Measure your Finger ( Circumference mm)
- 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.
- This measurement will give you your finger circumference.
