Is a 4.5 Inch Girth Big? Small? Average?

There have been many, many studies measuring penis size over the years. The most up-to-date data comes from a 2015 systematic review (an analysis of many studies) published in the British Journal of Urology titled “Am I Normal?

By analyzing data from many other studies, they concluded that the average penis was 3.66 inches around when flaccid and 4.59 inches when erect. So, a 4.5 inch penis girth when erect is just under the average.

Here’s a graphic from the article that shows the data:

What does this data tell us?

  • Fewer than 10% of all men had a penis girth of less than 10 cm (3.93 inches) when erect.
  • Another 20% or so had penis girth between 10 cm and 11 cm (4.33 inches).
  • About 35% had penis girth between 11 cm and 12 cm (4.72 inches).
  • About 25% had penis girth between 12 and 13 cm (5.12 inches)
  • Less than 15% had penis girth greater than 13 cm.

The vast majority of men—about 80%—have a penis girth between 10 cm and 13 cm (3.93-5.12 inches). A 4.5 inch girth is well within the normal range.


Help! My Girth Isn’t Enough!

What if you don’t have anything near a 4.5 inch girth? Is there anything you can do to address it?

First, you should know that if you typically have sex with women, the majority of heterosexual women—85%—are perfectly satisfied with their partner’s penis size. Penis size does not, in general, play a huge role in women’s sexual pleasure. By contrast, only about half of the heterosexual men surveyed in this same study were satisfied with the size of their own penis. (Unfortunately, there’s not as much data available on gay men and penis size).

This just goes to show that a lot of penis-size dissatisfaction, whether centered on girth, length, or both, is not necessarily rooted in sexual satisfaction or in a penis size that’s outside the normal range (since most penises, as it turns out, are normal). It’s purely psychological.

Here are some things you can do if you are really coveting a 4.5 inch penis girth (or feel like your 4.5 inch girth isn’t enough):


See a Therapist

The best thing you can do for yourself is to see a sex-positive therapist to discuss your own feelings about your girth. A therapist will help you to get a realistic sense of your own penis size and how it compares to others. If you do have an unusually small penis girth, a therapist can help you to process any feelings you have about this. No matter your girth, a therapist can help you improve your own relationship with your penis, your body, and your sexuality more generally. They can also give you strategies for navigating uncomfortable or potentially negative situations in sex and dating.


Create Comfortable Sexual Situations

If you feel very self-conscious about the girth of your penis, it’s important to make sure that you feel comfortable and relaxed heading into any sexual situations. In sexual situations where you feel anxious, you may have trouble maintaining an erection, which will in turn increase your sexual anxiety (and your anxiety about your girth being inadequate). This creates a negative feedback loop.

It may be best to avoid sexual encounters with people you don’t know well and wait until you have built trust and comfort with someone before becoming intimate.


Expand Your Sexual Repertoire

If you are looking to create a fuller feeling for your partner during penetration, there are positions and devices that you can take advantage of:


Make Healthy Lifestyle Choices

Exercising more and eating right can help you to have better cardiovascular health, which can help you to have harder erections. Harder erections give the impression of a larger, girthier member. 

Avoiding excessive alcohol and cigarette consumption can also help you to have more reliable erections.


Surgery and Devices

Some people consider surgery or devices like penis pumps as a last resort. Various surgeries and devices purport to be able to increase your penis size. However, even among the few procedures and implements that show long-term results, they tend to only increase length and have a pretty negligible effect on girth.

Girth-specific procedures involve injecting fat into the penis. Unfortunately, in this procedure, the fat often settles unevenly, leaving you with a lumpy penis. Sometimes, the fat is just re-absorbed into the body!

A new surgery with silicone implants increases length and girth, but it’s still in the early stages and is not a widely available procedure yet.


4.5 Girth: The Bottom Line

As it turns out, a 4.5 inch girth is right below the average penis girth of 4.59 inches. And most penises are right around the 4-inch to 5-inch range in terms of girth.

However, if you are short of a 4.5 girth and you feel anxious about it, here’s what you can do:

  • Therapy: This can help you get a realistic sense of your own size and have a better relationship with your own body.
  • Comfortable sexual situations will help you stave off sexual anxiety, which can hinder your performance and create more anxiety.
  • Certain positions and devices can create a fuller feeling during penetration.
  • Healthy lifestyle choices will help you maintain harder erections, which feel bigger.
  • Most surgical procedures and devices won’t have an impact on your girth, although there are some experimental procedures that may be more widely available in the future.

Ultimately, whether you have a 4 inch penis girth, a 4.5 inch girth, or anything else, you are capable of having pleasurable and fulfilling sexual relationships.
