Measuring for a Ball Stretcher
To measure for a ball stretcher, you should take several measurements, preferably at different times. After a warm bath, when you are soft or hard, when it is hot and when it’s cold.
To measure, you will need a string or seamstress measuring tape you can easily wrap around your testicles. You should measure at the point just between the base of the penis and top of your testicles. If needed, pull your testicles down so you can wrap the string or measuring tape around.
Once you have the tape is in place, pull it tightly enough so your testicles cannot slip through, but don’t make it too tight or else it won’t be comfortable and can cause damage. When the tape is wrapped around, mark the spot on the tape where it comes together.
This is the circumference, not the diameter, to convert this number into diameter, for the size of a ball stretcher you need, divide the circumference by 3.14 (the rounded-up value of pi). The number you get this way is the diameter.
For width, instead of wrapping the string or measuring tape around, you measure the from the top of the testicles and the base of your penis, that will give you the width. I have 1", 1-1/2", 2", 2-1/2" and 3”.
