Your Size

1. Grab a soft measuring tape.
2. Get an erection.
3. Measure from your pubic bone, right to the end of the tip. There ya go! Measure your girth by wrapping the tape measure around your shaft at the base while erect.

What's Small?

Medical doctors utilise a threshold when considering penile augmentation. This threshold is men with a flaccid length of under 4 cm , or an erect length shorter that 7.5 cm would be considered for the surgical procedure. Research

What's Average?

Numerous international studies reveal that the average man has a penis which measures 8.8 cm when flaccid and 12.9 cm when erect. Studies have also concluded that there was no correlation between erect and flaccid penises. An American study had 1,600 men in 2014 take their penis measurements. The results were harmonious with other studies and concluded that the average erect penis in the US was 14.2 cm with a circumference of 12.2 cm. Research


The downward view of your penis may make it appear smaller than from other angles. Research. The comparison from your top-down view and comparing it with other men's genitals from a different perspective may reinforce false ideas of your penis size. But do partners have a more dependable view? One study suggested that while the majority, some 85 per cent, were satisfied with their partner's package, guys seemed less sure of themselves. Research. 45% of the studied men thought they had a smaller penis, but researchers found that a smaller size penis was very unusual. Research. In another study, it found that it was only a "substantial" issue to a "clear minority" of the respondents. The majority of men's anxiety about penis size looks at the length, respondents are more interested in width, according to one study. Research. Another study reported that for a majority — 9 out of 10 of the respondents — penis girth was more important to sexual satisfaction than penis length.

What Works?

Another study utilised 3D models of 33 different shape and sizes. The models ranged from 10 cm to 21.5 cm in length, and from 6 cm to 18 cm in circumference, based on average American penis size when erect of 15.2 cm long with a circumference of 12.7 cm. The 3D models were blue so as not to influence respondents as to race etc. The 75 participants indicated their size preferences from the blue models chose diversely depending on the kind sex they were thinking about but; demonstrated that in the end to be only slightly above the averages found across studies:

For long-term sexual partners, the penis was a slightly shorter circumference and length compared with their choices for one-night stands, choosing an average length of 16 cm and a girth of  12 cm.

For casual sex partners, the desired length was 16.5 cm and a circumference of 12.5 cm.

Mind Games

The number of men seeking penile enlargement procedures continues to increase.

Research has indicated that most men who seek surgery to lengthen their penis have an incorrect or miscalculated idea of what a normal is.

Size and Weight

The study found a weak correlation between greater BMI and shorter erect penile length when this was measured from the skin over the pubic area, but not when the measurement was made from the bone to the tip.

This suggests that the penis would appear to be shorter when there is more fat under the skin at the visible base of the penis.

Penis Anxiety

All Things Being Equal

The scientific research demonstrates the facts behind the misinformation, and anxiety men may have over their penis. You have what you have, and if you’re using it right, there shouldn’t be an issue.

If you are still concerned or have anxiety talk with your doctor or contact mensline to discuss or deal with your concerns.

Penis Q&A

Penises are not symmetric. They naturally hang to the left or right. The right testicle on average is larger while the left testicle usually hangs lower. It may even bow in either direction when erect.

No, pills may increase blood flow to your penis, but your penis will not get any bigger.

Yep sure can. It’s uncommon, but does occur. The penis is boneless and has chambers that inflate with blood when erect. If you are a little too firm, bend it too far or get a little too vigorous the chambers can tear. It is painful and some report a cracking noise when it happens. It will become swollen and bruised and it’s best to visit your medical provider for assistance.

Nup, no way. Many scientific studies have proven there is no correlation to hand, nose, finger or feet size and your penis.
