Penis Size: The True Average

Just ran across this article while…um…well…

In any case, it confirms several numbers often tossed around although it does not specify BPEL or NBEL. For those too lazy to check it out, average length around 5.1" (but also provides a range up to 6.3"), average girth of 4.7". Apologies if posting an outside link violates any rules, it surely isn’t my intention. Just trying to share information.

What is the average penis size?

In the last paragraph they suggest using extenders or traction devices before going to surgery !

Abstract
This study aimed to establish a reference range of penile length and circumference of adult males in China, and to compare the penile dimensions of different ethnical backgrounds. To do this, penile length and circumference measurements were obtained from 5196 healthy males attending the Urology Counseling Clinic. The mean value of penile dimensions was a flaccid length of 6.5±0.7 cm, a stretched length of 12.9±1.2 cm and a flaccid circumference of 8.0 ±0.8 cm. In the subgroup of 311 males, the mean erectile length was 12.9±1.3 cm and the mean erectile circumference was 10.5±0.9 cm, the mean flaccid and erectile glans lengths were 2.7±0.3 and 3.4±0.4 cm, respectively, and the mean flaccid and erectile glans diameters were 2.6±0.2 and 3.4±0.4 cm, respectively. We found that flaccid penile length and circumference varied among different ethnicities. This study established a reference range for penile dimensions, which will help when counseling patients worried about their penile size or seeking penis enlargement surgery. We also found that penile dimensions are different in different ethnicities, but further investigations are needed to validate this.

Marinera, what’s the method of measurements in this study? for the erect lenght bp or nbp?

There were two groups: one measured only stretched, a subgroup of 311 also erect; the latter had an average of 12.9 NBP

“The stretched flaccid length was measured as the distance from the pubic bone to the tip of the glans, under gentle painless extension of the penis (Figure 1b). The erect length was measured as the distance from the pubic bone to the tip of the glans (Figure 1c). The penile circumference was measured at the middle of the shaft (Figure 1d).”

There can be some doubt that it was BPEL, actually; pics don’t help much

Ok, thanks, so approximately a 15cm BP average lenght.

Well we don’t know the average fat pad :) .

Now that I re-read the full study
“The stretched flaccid length was measured as the distance from the pubic bone to the tip of the glans, under gentle painless extension of the penis (Figure 1b). The erect length was measured as the distance from the pubic bone to the tip of the glans (Figure 1c). The penile circumference was measured at the middle of the shaft (Figure 1d).”
there still could be some doubt that meauserement was BP. See by yourself if pics help

clearly bpel with a cold metal ruler :(

Looks like they’ve been reading how to measure a penis on Thundersplace. ;)

I wonder if they shaved everyone they measured? :D

Great study!
Clearly looks like BPEL and BPFSL to me.
Would have loved to see such a well documented study with subjectgroups from all over the world.
It is a funny thing to read that not one of all 5196 measured men surpassed myself in any category other than glans length.
The flaccid/stretched/erect correlation chart is a really neat feature and confirms, I believe, what we all thought

Their linear regression model for the EL confuses me. EL=(0.936+0.761 × (SL)) gives significantly lower EL than the chart would suggest. The line there just looks like EL=SL.

Which table are you referring too?

This one is interesting also

Wow I hope those stats are true.. If so I’m already above the 95th percentile in all categories:

BPEL = 18.1 cm (7.1”)
BPFSL = 17.1 cm (6.75”)
EG = 13.3 cm (5.2”)
BPFL = 13.0 cm (5.1”)
FG = 11.0 cm (4.4”)

Too bad the study wasn’t done with a larger sample size, but it does seem to be more proof the average BPEL is just under 6”, as hard as it is to believe.

The one to the right.
The function does not look like EL=(0.936+0.761 × (SL)) at all. It is much steeper.

Yes your stats are pretty good. Keep in mind though that this study was performed in china. Compared to the other studies (marineras last link) this study’s length does not fall short though.

The sample size is great!! Of course, erect sample size could have been better, but the study shows how well stretched and erect length correlate.

I would not call 5.079" just under 6" either.

I think it is a semi BP, in the sense that pressed but lightly, not a real BP. It must be said, however, that the measurement is taken lying down and not standing up like you should do, then we can say that it is equal to a BP outlet in the foot with dick parallel to the floor.
