Penis Size

How can I tell if my baby’s penis is the normal size for his age?

Penis Size

Dr. Greene’s Answer:

In determining size, the “stretched penile length” is far more important than the “relaxed length.” To evaluate penis size, stretch the penis gently and measure from the bone at the base all the way to the tip. Be sure to depress the surrounding fat pad to get all the way to the base. Here are the normal values:

Average Stretched Penile Length 
(Adapted from Feldman KW, Smith DW. Journal of Pediatrics. 1975; 86:395):

Age
Normal: Mean +/- 1 SD (inches)
Abnormal: Mean – 2.5 SD (inches)
0-5 months
1.5 +/- 0.3
0.75
6-12 months
1.7 +/- 0.3
0.9
1-2 years
1.9 +/- 0.3
1.0
2-3 years
2.0 +/- 0.4
1.1
3-4 years
2.2 +/- 0.4
1.3
4-5 years
2.2 +/- 0.4
1.4
5-8 years
2.4 +/- 0.4

    Hey I was just wondering if 2 1/4 inches is normal for a 13 year old

      Size isn’t based on age, but stage of development. Check out this post, Tanner Staging, to get a better idea of your stage of development.

    • Hi Zayne,

      You can determine if your size is normal for your development by following these steps:

      1. The average stretched length of the penis before puberty is somewhere between 2.1 and 2.9 inches.
      2. The average stretched length of the adult penis, after puberty is complete, is between 4.6 and 5.8 inches (though a more recent study of 6200 boys, mostly white, from Bulgaria, put the average at 3.1 to 4.3 inches).
      3. During puberty it is normal for the stretched length to range between 3 and 4.5 inches.
      4. It can be normal in our culture to begin puberty as early as 10 years old or as late as 14.9 years old.
      5. Puberty is NOT set by your age, but by your Tanner Stage (the system doctors use to evaluate development during puberty).
      6. If you are not in the normal range for your stage of development, or if your development is before age 10 or after age 14.9, it’s wise to discuss this with your pediatrician.
      7. During puberty it is recommended that you have a physical exam once a year. Unless you particularly concerned or are far outside the guidelines above, you can bring this up at your annual exam.

      In the medical literature, the sizes are based on the stretched length. To measure the stretched penis length, stretch the penis gently and measure from the bone at the base all the way to the tip. Be sure to depress the surrounding fat pad to get all the way to the base. Once you’ve done that, follow these steps to determine where you fall developmentally:

      1. The average stretched length of the penis before puberty is somewhere between 2.1 and 2.9 inches.
      2. The average stretched length of the adult penis, after puberty is complete, is between 4.6 and 5.8 inches (though a more recent study of 6200 boys, mostly white, from Bulgaria, put the average at 3.1 to 4.3 inches).
      3. During puberty it is normal for the stretched length to range between 3 and 4.5 inches.
      4. It can be normal in our culture to begin puberty as early as 10 years old or as late as 14.9 years old.
      5. Puberty is NOT set by your age, but by your Tanner Stage (the system doctors use to evaluate development during puberty).
      6. If you are not in the normal range for your stage of development, or if your development is before age 10 or after age 14.9, it’s wise to discuss this with your pediatrician.
      7. During puberty it is recommended that you have a physical exam once a year. Unless you particularly concerned or are far outside the guidelines above, you can bring this up at your annual exam.

    Hi I’m Ryan. I’m 13 and at my age (8th grade) a lot of sexual things go on at school and I’m worrying about my penis size. It’s [redacted]. I’ve never ejaculated before and I still can’t if I try. I was born in July so I’m one of the youngest in my grade. Is my penis bad or am I ok?

      At 13, this may be completely normal. The thing to consider is your Tanner Stage. Puberty is NOT set by your age, but by your Tanner Stage (the system doctors use to evaluate development during puberty).

      The size you stated is just larger than normal for pre-puberty. Depending on your Tanner Stage, you may be a little behind. It’s worth bringing up at your next regularly scheduled physical.

      At 13, almost 14, you should have a regular physical once a year.

      At 10, you probably haven’t started puberty. If that’s the case, the average stretched length of the penis before puberty is somewhere between 2.1 and 2.9 inches.

      It would be appropriate for you to discuss this with your doctor.

    Hello,

    I’m a mom of two boys, a 2-year-old and a 6-year-old. My younger boy’s penis is bigger than that of his big brother’s and I can already see that it is quite open while his brother’s is still very tight. It worries me… a lot! We are thinking of having him circumcised but I’m worried about it too! Will it eventually open up should we leave him uncircumcised?

      Definitely leave your sons intact and not circumcised. Circumcising removes the most erroneous zone on a boy and also decreases his length! Only amputate if there is rampant disease present. Your sons are healthy and need no cutting.

      The average stretched length of the adult penis (after puberty is complete) is between 4.6 and 5.8 inches. You’re likely not done with puberty and will likely grow more before you finish puberty.

      Before Puberty the average stretched length of the penis is somewhere between 2.1 and 2.9 inches*.

      The average stretched length of the adult penis (after puberty is complete) is between 4.6 and 5.8 inches (though a more recent study of 6200 boys, mostly white, from Bulgaria, put the average at 3.1 to 4.3 inches. There’s a lot of variation between studies!)

      During puberty, it depends more on Tanner Stage than it does on age.

    When my son was born, the urologist said he had a slight twist in his penis. We had to decide whether or not to go ahead with the circumcision. She said it was very minor, only enough where she felt that she should make us aware before proceeding with the procedure. Now he is 10 and his penis in extremely small. We have a 3 year old who’s penis is larger (I think). I try not to oogle either, but I am wondering if I should be concerned.

    • Dear Adham,

      I see you’ve left a series of questions here. All questions wait in moderation until a live person has an opportunity to read them and make sure they’re reasonable comments or questions. You see, some people think it’s okay to write whatever they think and post it on a web site. In an attempt to raise the level of conversation on the web, we don’t post those comments.

      To answer this question:

      1. You say you are 12. The size you stated is already an adult size as stated in the post above.
      2. If you’re worried about it being too big (which is not what most boys worry about), then you can see this post for a guide on how to tell how much more you may grow.
      3. The post above also says, “If you are searching on information about penis size during puberty, please go to Penis Size During Puberty for your answer.”

      Adham, I hope this eases your fear, but you will have to actually read and learn to get your full answer.

The reason i believe this may be “unordinary” is the fact the article said that the normal size for children around the age 11 should have a normal 2-3 inches.

      Changes in puberty are linked to stage more than age. If you still have questions after looking at the Tanner Staging chart, talk to your doctor to determine if your size is on track for your stage of development.

    My son is 10 years old and his penis does not seem to have grown since he was a baby. I did see a doctor a few years ago and he told me not to worry it would grow later. His testicles have grown but not his penis and I am worried this is going to cause issues for him later. Also his skin does not pull back so one doctor once told me he will have to be circumcised later. Except for a few times as an infant he has never had an erection. I thought even as little boys it was normal sometimes and is this something I should be worried about and could all three issues be related. Thanks.

      When your penis gets randomly hard that’s called an erection, That’s perfectly normal as it comes from sitting in awkward positions or thinking about sexually things. don’t worry if you think it’s too short, It’ll grow

    • Hey Mike,

      The average stretched length of the penis before puberty is somewhere between 2.1 and 2.9 inches.

      The average stretched length of the adult penis (after puberty is complete) is between 4.6 and 5.8 inches (though a more recent study of 6,200 boys, mostly white, from Bulgaria, put the average at 3.1 to 4.3 inches.)

      If you are outside those sizes, it’s wise to see your doctor and have a physical exam.

      I’m not sure you understand what sex actually is..
      Having a circumcised penis is a medical or even religious decision that your mother & Doctor make at birth.. Sex works the same way whether you are circumcised or not.
      However, if you are referring to the “feel” of sex with an uncircumcised penis, then I wouldn’t actually know about that. I’m sure there is another forum to discuss it though.

      I hope you have seen the post that we published to address Penis Size During Puberty. If you haven’t, read it now as it will answer some of your questions.

      All boys and girls develop at different rates. This means some will be behind others in their development. Regardless of whether you are on track or not, your concern over your penis size is enough reason to discuss this with you pediatrician or family doctor. You can bring it up at your next appointment. Your doctor will likely do a physical exam and can tell you if you are the appropriate size for your stage of development or not and provide direction if you need further help.

          Hi Kelly,

          Your post was a bit confusing.. Is he below or higher? If he was born early then that doesn’t necessarily mean that his growth won’t be on target. However, if he is having tests done like you said, then most likely another doctor will be able to give you a result to those said tests.

    • At 14, with your strong feelings, it is wise to discuss this with your pediatrician. At your age, you are due to have a physical exam each year. Typically your pediatrician will ask your parent to wait in another room for your exam and he* will ask you if you have any concerns that you’d like to discuss in private. He will be able to help you.

      If you don’t get a regular check up, ask your mom or dad to make an appointment for you to be checked. If that’s not possible, the next time you’re sick with something like a flu bug, use that as a reason to see your doctor — then ask to talk to him about something else. That happens frequently. But, I’d suggest, if you’re going use this tactic, be sure to tell him first thing that there is something else you want to discuss so you don’t run out of time.

      Hope that helps.

    My son is 2 yrs old and I am concerned about his penis. When he was born, it was barely visible. His pediatrician insists nothing is wrong. The length is borderline based on the chart above, just under 1 and a quarter inch stretched out. But the circumference or thickness is much smaller than usual. It’s the thickness of a standard #2 pencil. What other doctor could give us a second opinion since the pediatrician doesn’t see a problem? Thank you,

    Hi Dr Greene, I love your website first of all. My son just turned 9 months old. When he was born, the doctor noticed that his penis size was pretty long while he was circumsizing him. However now both genitals look small. Can it be possible? I don’t really know what small is but it doesn’t look long and the tip is kind of covered with the top skin. My boy is very tall and slim. 9.7 kg and 75 cm. The pediatrician said it looks a little small. I have a thyroid disease. Can it be related to that, or circumsion, or nothing to worry about? I would be very happy if you could write me back please. Many thanks!!! Regards.

    • I suggest you have a physical exam and discuss this with your doctor.

    I feel uncomfortable talking about this but I am 10 and a half. My parents tell me it is totally OK to talk about this topic because it is going to be very relevant very soon. They are 100 percent ok with me asking questions. Anyway,

      10 and a half is my age by the way. Also, I am 0.5 above average both ways. I read up on it and it said that it is okay for “My special me time” at any age- most adults actually said they would apologise, walk out of the door and when they are done say that they will knock next time and said it is ok.

    I am the same age, and used the chart, I am 0.5 above average all time so that’s bigger.

    Hi

    I have a urgent question . Please help me . I was born in 1993 Sep and now I’m 22 years old . My penis size is around 1.5″ Flaccid (non erect) and 5.5″ (erect) . I think my flaccid size is very very abnormal and really it looks like a very young boy’s penis whereas my brothers size and form is very different and actually they have normal size. I remember that since I was 12 years old until now my penis size and form not change in flaccid shape. What is the main reason? Is there a treatment ? Oh I should tell you since childhood I like to put a pillow or something like it between my legs so that it press my penis and testicle and this was very pleasant for me during sleep and rest. I think doing this about 10 years prevents enlargement of my penis. Is it related to my problem or not?

    Thanks a lot …

      Hello, don’t worry at all. You will have done yourself no damage. Your size is average when erect, not a problem and flaccid state is fine too – you are a grower. I personally am quite small when flaccid, but grow to a good size when roused. You are absoutely fine and should not worry.

    It is actually normal, well, for a 12-13 year old.

    It is disturbing that any type of professional would allow a space to perpetuate male’s fears of not having a “big enough” penis. How is this helpful to our sons? This should be deleted.

    • Hi Brett,

      Thank you so much for your comment. You raise an interesting and complex question. I must admit, we’ve been struggling to find the right balance. Here is the background —

      When Dr. Greene wrote this answer he was addressing the parent of a baby who was concerned about a medical condition. As a pediatrician, this is a question he gets routinely and a valid one. Recently we started getting comments from a lot of adolescent boys asking about their own penis size. We moderate all comments and have guidelines, for instance we don’t post hateful comments, comments that call other people names, spam, or anything pornographic. We do allow differences of opinion and respect multiple points of view. Where do these new questions fall within our guidelines?

      Our first thought was we needed to update our chart on penis size so these boys could just look on the chart and have their answer. You may have noticed that the chart skips from 11 years-old to adult without data. Interestingly when Dr. Greene did the research to find the answers he found there was no trusted data on normal penis size in adolescent boys. That meant we couldn’t just add to the chart.

      What we have done in the short run was to carefully read each comment and try to decide the intent of the boy writing in. Was this a joke? Was it pornographic? Was it an honest concern? Did it make fun of anyone else? We aren’t perfect (that is certain), but based on these reasons, we do not publish many of the comments made on this post.

      So why would we publish them at all? By the time kids reach puberty most have been exposed to photos, typically online or in the media, that show the human body in unrealistic proportions. Typically these photos are sexual in nature, but not always. It is our hopes that in the absence of scientific data, by allowing adolescent boys to post their honest question about the body part they feel most insecure, they will see that they are not abnormal. We know the sizes they post can not be trusted due to differences in measurement techniques and the human tendency to make ourselves appear better in other’s eyes.

      We would love your feedback. After you hear our reasoning, do you still think we should delete all these comments?

      Thanks again for voicing your concern.

    There’s a large range of what is “normal” for penis size. They grow at different rates for different people. Plus, I’m a woman telling you that penis size doesn’t really matter to most women, and who knows better than a woman?

    Yes, yes, of course. That’s very natural. And remember that no matter what your friends or other kids at school say, penis size does not have anything to do with your worth. It’s not a bad thing to be below average, or above average. Penises (and vaginas) come in many different shapes, colors, and sizes, but if you’re experiencing pain or abnormally strong, stinky smells coming from that area (it’s natural for it to smell not-so-great sometimes, though. Just make sure to clean yourself regularly), please, please, please know that going through the embarrassment of letting your parent(s) or guardian(s) know about your issue will be so much easier than dealing with what could potentially end up as a life-long issue that could cause problems with self esteem and relationships and/or result in continuous pain.

    But seriously, I know for absolute sure that penis size does not tie into your value or worth. It’s completely okay to look different from other guys in pictures or videos, because they were specifically selected because they match what we, today, think of as having the ideal penis. Believe me this, though. M a n y, if not most, penises (and testicles – some hang lower than others. Some are larger or smaller than others) look very different from those that are currently put in pictures and videos, and as long as you are healthy, there is nothing bad about the way that your penis (and the rest of your body) looks.

    • Thank you for this wise reply. It’s a great reminder to us that models are not “normal”. I love this video, especially the end. It shows how the media distorts our views of real people and real bodies.

    I’m not sure if you measured your penis correctly as many of you young kids in this forum state lengths that I can’t even achieve and I’m in the upper area of my age group. I’m mid 14 and I’m 4.8 inches. I have done the research.

    You people are all lying. I don’t think that you guys know how to correctly measure your penis. I am turning 15 in October 2015 and I’m 4.8 inches. I have done the research. I am in the above average for my age group. So 4.5 inches is fine Mike.

      • Hi Kevron,

        I know it seems odd, because we used to respond to questions about size, but we’ve since decided that we need to direct readers to a post we wrote just for boys going through puberty. You can find that information at Penis Size During Puberty.

        Hope that helps!

    Don’t worry. I’m the same age and mine is small too. Girls don’t usually care that much about it as much as it might seem they do. We’ll be fine, not everyone is perfect.

    Hello, when measuring my son’s penis should I go by the stretched or the erect measurement? It appears that the erect measurement is about half an inch longer than the stretched measurement.

    My son just turned 2 years old and his penis is 3 CM is this normal? When he was born a urologist questioned if he had micropenis the endocrinologist didn’t say, just that he was smaller than average.

      I seriously doubt that your 5 year old son is 20 cm… did u pull his skin forward instead of back to measure? less than 7 cm would be about average.. 20 cm is very unlikely
