Measuring yourself - don't overthink it

Pi calculated ruler for circumference to diameter with recommended sizing. use it by wrapping it around and wherever the zero line falls is what the sizes you should get.

if you message me saying you think you got the wrong size my first question is going to be: When you measured yourself what did you come up with?

1. Use my printable tape here .svg or .png

2. vernier calipers i have a set for $1 plus shipping here: 80mm-calipers

3. cloth sewing tape measure.

4. using a camera over a ruler is not an acceptable way to measure. parallax is the issue.

5. eyeballing is not acceptable unless you have a calibration certificate saying your eyes are accurate to within +/-.01mm.

If you are unsure of what size to get after measuring message me

We are looking for the diameter of the glans at the widest part. if you use a cloth tape measure thats circumference we'll need to divide that by 3.14 to get diameter

CAR-1 and my tugger - You want to order a size that is +/- 2.5mm of what you got when you measured yourself. do not go down a size thinking it'll grip better it'll be uncomfortable. i was getting complaints about pinching most of pinching issues were because the wrong size was purchased (they sized down instead of staying within 2.5mm) that's why my printable tape says to go up.

frenulum is notch necessary for their primary uses direct air and tugging. it may be an issue if you want to use them as a retainer. they sit higher on the glans so it might not interfere with the frenulum.

My retainer regular or notched is more forgiving on sizing but will stay on and be more comfortable going down a size. example: you measure yourself at 37mm get the 30mm retainer.
