Ensure that the ring’s inner surface matches the circle on the paper. Maybe your size is between and does not match completely with one of the circles. May you are not sure that you have accurately identified the most suitable circle.
Of the two possible sizes, it is recommended to choose the larger one. If there is serious doubt, it is better to use a different measurement method.
You can use another measurement method if you don`t have an example. To do this, you must take a paper strip or thread and wrap it around your finger. The thread or strip of paper should lie comfortably without squeezing the finger.
You also need to make sure that it passes through the joint. Mark with a pen or pencil the place where the edges meet. Next, we measure the length of the thread or paper strip using a tape measure or ruler.
After calculating the circumference, we need to find the diameter. To do this, divide the resulting number by 3.14. For example, the circumference is 54. Dividing this number by 3.14, we get 17.1. Therefore on the UK scale, it is an N. On the American scale, it is a 7.
