All sizes on this site are in centimeters (not inches) and all measurements are hard measurements (not soft or semi). Do not pump your cock beforehand, and do not put on a cock ring.
Don’t guess: Measure.
Even though it’s easy to convert from inches to centimeters, don’t. Measure in centimeters. You’ll be less likely to do the thing where you are aiming for (and creatively rounding to) a certain “milestone” in inches.
Use a cloth tape measure. Do not use a ruler.
Measure length along the top. Your cock should be pointing out away from your body—not up or down.
Don’t measure it along the bottom or the side. If the ruler is touching your scrotum, you’re doing it wrong. The bottom of the ruler should be where your cock touches your pubes.
Use a cloth tape measure. Do not use a metal tape measure. This will give you an inaccurate measurement.
Measure around your dick, not across—by girth, we mean circumference, not width.
Don’t measure the girth around the thickest point of your dick. Don’t find the thinnest point either. Find a cross-section that is about halfway in between these two. Put the tape measure around your dick and pull it snug.
If you vacuum pump your cock, please wait 72 at least hours after you have last pumped to measure your girth.
Just so no one’s surprised after the fact, if you claim a length or girth greater than the site average when you register, you will be required to verify this with measured pics.
When your bulge pic is uploaded and approved, that will start a one-week timer. You have one week to upload your verification pics. If the timer expires and you have not uploaded your pics, your account will be frozen. You will be able to log in when your account is frozen, but you will be unable to do anything but upload your verification pics after that point.
