Most men at some point want to know whether they have an
average size penis. How big is a normal penis? Once and for all, we
took a look at the actual scientific studies on the issue.

Most men underestimate the size of their penis for one simple
reason-- they measure it looking down. Second, to get the most
accurate measurements for a penis size, you have to take several
measurements at different times, preferably with different erections
on different days. Then average these figures together.

Why? Your penis changes size. It is bigger when your arousal is
bigger. It is bigger when the temperature of the room is warmer. It
is bigger , for some men, in the mornings. So, taking measurements
at different times of the day helps too account for what may be
natural variability in size of your penis due to factors such as arousal
level, time of day, room temperature, and frequency of sexual
activity, and unreliability of the methods you use to measure your
penis.

Length
The length of your penis can be measured with the subject standing
and the penis held parallel to the floor. The penis is measured along
the top, from the base to the tip. Results are inaccurate if the
measurement is taken along the underside of the penis, or if the
subject is seated or prone.


Thickness--Circumference
Long penis, no width makes for a pencil dick. Penis girth is the
measurement of the circumference of the completely erect penis. It
is variously quoted as an average of three measurements: just
below the glans penis, in the middle of the shaft, and at the base.[2]


Problems
A penis must be completely erect in order to obtain an accurate
measurement. This may be difficult to achieve in a clinical setting. At
least one Brazilian doctor resorted to injecting penises with drugs to
induce erection, which gave more consistent results.[4] Some
clinicians measure the penis by stretching the flaccid penis as far as
comfortably possible. Self-reported measurements tend to be
unreliable because men often want to report a larger penis size.


The Bottom Line From Studies on Penis Size
How big is an average penis? While results vary across studies, the
consensus is that the average human penis is approximately 5.1 to
5.9 inches (12.9–15 cm for you Europeans) in length.

How thick is an average penis? The average thickness is 4.85 inches
around (12.3 cm) when fully erect.

Size at birth

The average stretched penile length (ouch!) at birth is about 1.6
inches (4 cm), and 90% of newborn boys will be between 0.9 and
2.2 inches (2.4 and 5.5 cm).

Limited growth of the penis occurs between birth and 5 years of
age, but very little occurs between 5 years and the onset of puberty.
The average size at the beginning of puberty is 2.4 inches (6 cm)
with adult size reached about 5 years later, around age 17.

Size with aging

The good news is that your penis does not shrink with age.  
“Individual research studies have ... suggested that penis size is
smaller in studies focusing on older men, but Wylie and Eardley
found no overall differences when they collated the results of
various studies [over a 60 year period].”[9]


Erect length
Several scientific studies have been performed on the erect length of
the adult penis. Studies which have relied on self-measurement,
including those from Internet surveys, consistently reported a
higher average length than those which used medical or scientific
methods to obtain measurements .

The following staff-measured studies are each composed of
different subgroups of the human population (i.e. specific age range
and/or race; selection of those with sexual medical concerns or self
selection) which may meet the definition of possible sample bias.

For the Scientific Types Here Is a Summary of the Studies


























A study published in the September 1996 Journal of Urology
concluded that average erect length was 12.9 cm (5.08 in)
(measured by staff).[5] The purpose of the study was to “provide
guidelines of penile length and circumference to assist in counseling
patients considering penile augmentation.” Erection was
pharmacologically induced in 80 physically normal American men
(varying ethnicity, average age 54). It was concluded: “Neither
patient age nor size of the flaccid penis accurately predicted erectile
length.”

A study published in the December 2000 International Journal of
Impotence Research found that average erect penis length was 13.6
cm (5.35 in) (measured by staff).

Quote: "The aim of this prospective study was to identify clinical and
engineering parameters of the flaccid penis for prediction of penile
size during erection." Erection was pharmacologically induced in 50
Jewish Caucasian patients who had been evaluated for Erectile
dysfunction (average age 47±14y). Patients with penis
abnormalities or whose ED could be attributed to more than one
psychological origin were omitted from the study.

A study conducted by LifeStyles Condoms found an average of 14.9
cm (5.9 in) with a standard deviation of 2.1 cm (0.8 in) (measured
by staff).The purpose of this study was to ensure properly sized
condoms were available.

401 college students volunteered to be measured during 2001
Spring Break in Cancún, Mexico, of which 300 gained an erection to
be clinically measured (without pharmacological aid). The 300
effective measurements makes this study double the size of any
prior study that uses medical staff to measure penis size.

Erect circumference
A study conducted by LifeStyles Condoms during 2001 Spring Break
in Cancún found an average of 12.6 cm (5.0 in) with a standard
deviation of 1.3 cm (0.5 in).

Similar results exist regarding studies of the circumference of the
adult fully erect penis, with the measurement taken mid-shaft. As
with length, studies that relied on self-measurement consistently
reported a higher average than those with staff measuring.


Flaccid length
One study found the mean flaccid penis length to be 3.5 inches
measured by staff). Length of the flaccid penis does not necessarily
correspond to length of the erect penis; some smaller flaccid penises
can grow much larger, and some larger flaccid penises cannot grow
much larger.

The penis and scrotum can contract involuntarily in reaction to cold
temperatures or nervousness, referred to by the slang term
"shrinkage", due to action by the cremaster muscle.
