1. Grab a piece of string/strip of paper, pen/pencil and ruler.

2. Wrap the paper/string around your desired finger.

3. Using a pen or pencil, mark the point where the paper overlaps itself.

4. Lay the strip of paper/string on a flat surface and use a ruler to measure the distance from the end of the strip to the marking you made, in millimetres. This will give you a measurement of the circumference of your finger.
