How to measure ring size at home

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 conversion chart below 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.

• This measurement will give you your finger circumference. Use it to find your size using our ring size conversion chart below
