Find the right size for a ballstretcher?

To determine the right size for the ballstretcher, ideally a flexible measuring instrument is used. This can be a flexible measuring tape, but also with a string or a shoelace in combination with a ruler or folding rule exact values can be determined.

The tape is applied directly above the testicles without pressure. You should always leave a little space so that a pen or little finger can still fit between the tape measure and the skin.

Once the circumference has been determined, the diameter can be easily calculated. Simply divide the circumference in millimetres by 3.14. Based on this measurement you can now choose the right size.
