The following table shows the ring sizes with different parameters: Italian measurement, ISO measurement, inner diameter and circumference. This method is used to obtone the inner circumference of the ring, its diameter or the size of your finger. For example, if you find an inner circumference of 53.5 mm from your measurements, the ring size will be the number 16. The right size to indicate in notes corresponds to the column with Italian Size.

The simplest and most immediate method is to use a tailor centimeter and measure the circumference of your finger. Than you can look for the measured value in the fourth column (Internal circumference mm) of the table that you find above and then you can find to what extent it corresponds in the first column of the same row. For example, if you measure 48 mm, the size of the ring is the number 8.
You have to be careful to read the upper measurement, for example if the measurement is a bit higher than 48 mm it is preferable to look for the measurement 49mm. However, we advise you to pay attention to the thickness of the centimeter and the width of the centimeter which can distort the measurement reading.
Also, you should also pay attention to the circumference of the finger phalanx (the joint where you bend your finger) because you may have a thin finger, but a wider bone so the measurement you choose may not be correct. Also remember that the fingers can be swollen by the temperature, for example in the summer you could have more swollen hands than in winter.
