Penis Size: The True Average

True, I didn’t notice until after I posted this was the same China study that was posted a page or two back. Also you are right about BP, the 5.9" was the 95th percentile, which seems to be questionable, as 5" BP does seem oftly small.

I think you should always add to any study on penis size a significative error correction, since you don’t know with how much force they stretched (what means gently and painless= 250 grams? 500?) or pushed inside the bone for EL. For example, it is amazing how this study accords with other studies to the millimeter as far as penis length, but did the other studies measured in the same way? I have to say I find strange the strict correlation between EL ans SL, there is a significative difference between the two for most of guys.

If they measured with a pump, we could have more homgeneous data. Say the subject’ penis is pumped ad 6hg for 15 minutes or whatever and you read the length.

Playing around with such statistics and the normal distribution is fun.

If size was normally distributed, a 5” FG would be 1 in about 473 million. (Chinese study).

4,7” (5” would require too many decimals for open office) FL would be 1 in 163 TRILLION :D . Their flaccid standarddeviations are really small!

Oh what better to do on a friday night…

Well from living out there I can comment that there is far less physical variation ‘person to person’ than in the West. Is it such a surprise that penile dimensions are not so very varied when hair colour, eye colour, typical bone structure, height etc. are not so varied either?

A 9” EL?

Hey anyone know where I can find the chart that shows penis size in % I cant seem to find it anywhere. Thanks :)

not sure about length but a girth one is here

Also, average reported penis size at Thunders pre-PE is about 6.2 x 4.9 erect after making some logical exclusions.

cheers mate, how come percentile 1 is low compared to others?

Please use upper case letters to start sentences please gentlemen. Thank you.

The studies are referenced in the chart. If you want to know what they did differently, search for the study and see how they did it. Maybe there is a difference in their sample, or the way they did measurements.

Most of them are not publicly available. For example the first I can just read the abstract which doesn’t say much:

Abstract
PURPOSE:
We provide guidelines of penile length and circumference to assist in counseling patients considering penile augmentation.
MATERIALS AND METHODS:
We prospectively measured flaccid and erect penile dimensions in 80 physically normal men before and after pharmacological erection.
RESULTS:
Mean flaccid length was 8.8 cm., stretched length 12.4 cm. and erect length 12.9 cm. Neither patient age nor size of the flaccid penis accurately predicted erectile length. Stretched length most closely correlated with erect length.
CONCLUSIONS:
Only men with a flaccid length of less than 4 cm., or a stretched or erect length of less than 7.5 cm. should be considered candidates for penile lengthening.”
Penile length in the flaccid and erect states: guidelines for penile augmentation

So not sure how they measured and with what; for example apparently doctors like to use a lot strips instead then rulers to measure the penis, which have a low degree of reliability: you measure two times, you get different readings.

Ponchietti measured SL, but doesn’t tell how, if I can recall.

For the above study (china) I calculated the numbers myself.
This site provides pretty good numbers: http://howlongismyschlong.com/ with data taken from

Percentiles never represent the actual distribution but rather a normal distribution with means and standarddeviations taken from the studies. This usually gives a good estimate but can lead to very extreme numbers with outliers.

Marinera: 9EL would be about one in 250 trillion. You would have to search 35714 earths to find one of those.
Now according to the link I posted above it would be 100% but actually, with the data given, it would be 99,9955%, or one in 22184.

Thanks. That’s interesting. So, purely basing on calculations, there can’t be any Chinese in the 9” +- something, so to speak. But, numbers on Chinese aren’t much different than numbers on other ethnicities, so it should come out that there can’t be any 9” EL penis. Or am I missing something here?

Is howlongismyschlong.com trustworthy or does it make results better than they are?
