Average Penis Length What is the average penis length?
There has never been an official investigation into the average penis length of adult men. Therefore the internet holds a wide variation of average lengths. The most common measurement (based on scientific research) is an average erect penis length of 5.5 inches (14cm), with the majority of penises somewhere between 5.3 inches (13.5 cm) and 6.3 inches (16 cm). Recent research about the average penis length shows that men from Stoke-on-Trent have the longest penis, and men from Bristol the biggest girth. It is hard to say what the real penis average in the UK is, because it really depends on the research.
What is the average flaccid penis length?
A flaccid penis measures about two-thirds the length of an erect penis.
The average flaccid penis length of a grown man is 3.9 inches (9.9 cm). How can I measure average penis length? If you would like to know how your penis compares to the average penis length you should measure from the pubic bone to the tip of the penis.
When does your penis stop growing?

you also need to learn how to measure length correctly as well what a lot don't seem to know!
To measure length correctly you should measure from the tip of your penis head not the tip of the foreskin if you have one to the pubic bone along the top edge of your penis as you look down on it with a tape measure or ruler, to measure girth measure around the mid point along the shaft to get the correct measurement not around the base!
