People often wonder is there any way to guess the size of a man’s penis without actually seeing it? Yes, according to several studies, there are some statistically proven indicators of what a man’s penis size may be. So if you have ever wondered how big a guy really is, here are the Top Five Ways to Tell Penis Size.
Of course, these studies are only going to give you some general indications of what penis size may be. There are always going to be guys that are outliers and do not follow the trend. The only way to know for sure is to check it out.

Flaccid Penis Length
Not surprisingly, the best indicator of erect penis length is flaccid penis length. We have all heard of the growers and showers thing. While that is true, it is also true that if you have a big flaccid penis then you will have an even bigger erect penis. If a flaccid penis is six inches long, you know it is going to be six inches erect at a bare minimum and probably quite a bit more. Several studies have shown this to be the case.
A recent study out of Japan measured the relationship between different body measurements and stretched penis length (SPL). Stretched penis size is generally considered to be the best indicator of erect penis size. This study found the strongest positive correlation to be between flaccid penis size and SPL.
A Turkish study of 1132 military aged men, found a very strong correlation between flaccid penis length and stretched penis length. This was a good study in that it was not a self measured study (surprise, men sometimes lie about penis size). Additionally, it was not really a volunteer study and it was in a military setting where men could opt out. One concern with voluntary studies is that men with shorter penises may tend to opt out due to embarrassment.
Big Nose, Big Hose
The next best indicator of penis size may be the size of the nose. A big nose probably means a big hose.
A recent study out of Japan, has shown on average there is a strong positive relationship between nose size and penis size. Statistics were gathered from 126 recently deceased men in the 30-59 year old age range at the Kyoto Prefectural University of Medicine. Statistics taken include weight, height, testes size, prostate weight, flaccid penis length, stretched penis length, penile circumference and nose size.
To measure how the size of the body parts were related to each other, the researchers determined the Pearson correlation coefficient. The Pearson correlation coefficient is the measure of linear correlation between two sets of data. The higher the Pearson correlation coefficient the stronger the correlation of the two numbers are.
To approximate the length of the erect penis, the researchers used the stretched penis length statistic. This means they stretched the penis out straight from the body and measured along the top side of the penis from the pubic bone to the tip of the penis. This measurement is thought to be the best approximation of erect penis.
The Pearson Correlation coefficient for the relationship between nose size and stretched penis length was 0.564 which is considered to be a strong positive relationship. So in general, the bigger the nose the bigger the erect penis.
Index Finger Size May Indicate Penis Size
Another indicator of penis size may be the size of the man’s fingers. For a long penis, you are looking for a long ring finger and a short index finger.
A 2011 study reported in the Asian Journal of Andrology indicates that the ratio of index finger size to ring finger size is a good indicator of penis length. This study of 144 Korean men found that the shorter the index finger was relative to the ring finger (also known as second to fourth digit ratio 2D:4D), the longer the penis was.
The study used medical professionals to measure both the finger lengths and the stretched penis lengths of the subjects. This provides for the most accurate type of data.
The ratio was determined by dividing the length of the index by the length of the ring finger. So the smaller the index finger the smaller the ratio. A smaller ratio indicated a longer penis. The average ratio was 0.97.
Example of calculating this ratio: Index finger 3.0 inches, ring finger 3.25 inches, Ratio = 3.0/3.25 = 0.923. This would be significantly below the average of 0.97 so would indicate a long penis.
The table below show the relationship of penis length to digit ratio. You can see that the smaller ratios on the left side of the graph have a much higher average penis length.
The study theorizes that levels of exposure to testosterone while in the womb helps to determine both penis length and digit ratio. The higher the testosterone exposure rate, the longer the penis length and the longer the ring finger (thus a lower index finger to ring finger ratio).
Tall Men have Big Penises
In general, there seems to be a weak relationship between penis length and height. The taller the man, the longer the penis.
There have been a few studies that have shown a slight relationship between height and penis size. While not as strong of a relationship as there is with the flaccid penis size, finger ratio or nose size, there does seem to be a connection. In general, the taller the man is the longer his penis tends to be.
- A study found in the First International Journal on Andrology found that, “In particular, the height is proportional to the length of the penis in flaccidity and in erection, and to the circumference in erection. “
- A recent study out of Japan showed a very weak correlation between height and penis size.
- From the Annals of Sex Research, The Relationships Among Height, Penile Length, and Foot Size article found a weak but statistically significant relationship between height and penis size.
Country Boys Have a Bigger Penis
One 2010 study in the Archives of Pediatrics & Adolescent Medicine indicates that country boys may be packing a little more in the meat department. This study involved 6200 white males and followed development of penis size from ages 0 to 19 years.
For some reason, males from rural areas constantly showed a larger penis throughout their development when compared to their city counterparts. The study tracked flaccid penis length only so we can not be sure that this is true with erect length. But we do know from our top entry on this list that flaccid penis length is a good indicator of erect length.
The study found that rural 19 year old men had a flaccid penis length of 9.72 cm (3.83 inches). Their urban counterparts had a flaccid penis length of 9.29 cm (3.66 inches). This was a statistically significant difference of rural men being 4.6% longer than urban men.
I am sure that this could lead to a bunch of conjecture as to why men from the farm have longer penises that city men.
So Is Penis Size Important?
The truth is that penis size is important if it is important to you. You should not feel embarrassed if your penis size concerns you. The most important thing is to try not to obsess about it.
If you are concerned about what women think about penis size, you should know that penis size is not the top concern of most women. Most women rank many other qualities or traits higher that penis size when picking out a male partner.
This being said penis size is a factor for many women. In addition to this, studies show that many women prefer a penis that is significantly larger than the average penis. For more information on the penis size preference of women read The Real Truth About Penis Size.
This is not to make guys panic or obsess about their penis size. This is to give guys an honest look at what they are up against. Medical and sexual health experts are quick to say that any penis that falls into the “normal” range of 3.9″ to 6.5″ is equally sufficient. This just does not match reality. The very top of that “normal” range is the preferred size of women.
What Can be Done about Penis Size?
There are not any quick and easy fixes for this question. Do not believe anyone who is selling you a magic pill that will increase the size of your penis. This will not work.
The first thing to do is to make the most of what you have. If you are not having extremely firm and full erections then you must address this first. These full erections will make your penis feel and look at its maximum size. I would first suggest a visit to your doctor to rule out any medical conditions. In addition to this, acoustic wave therapy like the Phoenix device treatments is an extremely effective way to improve erection quality.
Actually changing the size of your penis is a much more difficult proposition. There are surgical methods but even these do not always work on their own. The scientifically proven method of enlargement that is used either with lengthening surgery on its own is the use of a high-quality penis traction device. These devices will slowly increase penis size over time. It is not quick or easy but it is the only method that has been proven to work.
