To know the size of a piercing you need to take into account 3 main measurements: the thickness of the bar, the diameter or longitude, and the diameter of the ball.

For example, in a Circular Barbell with two balls, the inside diameter of the hoop and the thickness of the bar is measured. To measure it you will need a Caliper.

Caliper: Instrument used to measure dimensions of relatively small objects, from centimeters to millimeter fractions.

On our website you will see it written as follows: 1.2 x 8 x 3. The first number corresponds to the thickness of the bar, the second to the diameter of the bar and the third refers to the diameter of the ball.Watch video.

In the case of an earring, you just measure the size of the ball or the gem stone.
