01Average Penis Size

The answer depends on who holds the ruler. Doctors measure less than men measure at home.

  • The average erect penis is 13.12 cm (5.17 inches) long when doctors measure it (Veale 2015, 692 men).

  • The average erect girth is 11.66 cm (4.59 inches) around when doctors measure it (Veale 2015, 381 men).

  • The average soft penis is 9.16 cm (3.61 inches) long (Veale 2015, 10,704 men).

  • Men who measure at home report more. The middle man in Epic's 2026 size data measures 6.26 inches long, erect and pressed to the bone (11,292 men).

  • The middle man in Epic's 2026 size data measures 5.00 inches around when erect (10,010 men).

  • US men who measured themselves at home averaged 14.15 cm (5.57 inches) long and 12.23 cm (4.81 inches) around (Herbenick 2014, 1,661 men).

  • A review of 33 studies with 36,883 men put the average erect length at 13.84 cm (5.45 inches) and girth at 11.91 cm (4.69 inches) (Mostafaei 2025).

02Penis Size Percentile Chart

The 75th percentile means longer or thicker than 75 out of 100 men.

  • Going by doctor measurements, half of all men are between 4.72 and 5.61 inches long when erect (worked out from Veale 2015).

  • The top 10% of men in Epic's 2026 size data measure 7.48 inches or longer at home. In doctor studies the top 10% starts at about 6.00 inches (11,292 men and Veale 2015).

  • The shortest 10% of men in Epic's 2026 size data measure 5.12 inches or less. In doctor studies that line sits at about 4.33 inches (11,292 men and Veale 2015).

03How Common Each Size Is

How many men reach each length. The doctor column is worked out from Veale 2015. The home column is our own data.

  • About 10% of men are 6 inches or longer when doctors measure. In Epic's 2026 size data, 63% of men measure 6 inches or more at home (worked out from Veale 2015, and 11,292 men).

  • A 7 inch penis is rare in doctor studies, about 1 in 400 men. In Epic's 2026 size data, 22% of men measure 7 inches or more at home (11,292 men).

  • 3.4% of men in Epic's 2026 size data measure 8 inches or more at home, about 1 in 29. Doctor studies put it at fewer than 1 in 10,000 men (11,292 men and Veale 2015).

  • 7.0% of men in Epic's 2026 size data measure under 5 inches at home. In doctor studies, about 40% of men are under 5 inches (11,292 men and Veale 2015).

Doctor shares assume a bell curve around the Veale 2015 average. Bell curves get rough at the far ends. Home shares are counted from Epic's 2026 size data, pressed to the bone.

04Home Measurements vs Doctor Measurements

Men who measure at home report more than doctors measure. Here is how big the gap is.

  • Men who measure at home report 1.10 inches more than doctors measure. The average in Epic's 2026 size data is 6.27 inches, against 5.17 inches in doctor studies (11,292 men and Veale 2015).

  • Pressing the ruler to the bone adds a typical 0.51 inches, in Epic's 2026 size data (6,954 men who measured both ways).

  • Without pressing to the bone, the middle man in Epic's 2026 size data measures 5.75 inches (7,378 men).

  • US men who measured at home averaged 0.41 inches more than men measured by doctors (Herbenick 2014 against Veale 2015).

  • Men round to easy numbers. In Epic's 2026 size data, 814 men logged 5.5 inches, but only 162 logged 5.4 and 105 logged 5.6 (11,292 men).

Why home numbers run higher

  • Men measure themselves. A man with a ruler is kinder to himself than a doctor is.
  • Pressing to the bone. Most men in our data press the ruler in. Not every doctor study does.
  • Who is in the data. Our numbers come from men who chose to train. They are not a random sample of all men.

05Penis Girth Statistics

Girth is the distance around the middle of the shaft when erect.

  • The average erect girth is 4.59 inches when doctors measure it, and half of all men are between 4.30 and 4.88 inches around (worked out from Veale 2015).

  • 8 in 10 men in Epic's 2026 size data measure between 4.09 and 5.95 inches around at home (10,010 men).

  • Length and girth are only loosely linked. The correlation is 0.42 in Epic's 2026 size data, so a long penis is not always a thick one (9,882 men).

  • 74% of men want more girth, on its own or with more length (Epic quiz, 18,980 answers).

06Penis Size by Region

Averages from studies where doctors did the measuring. Studies measure in different ways, so small gaps between regions mean little.

  • Only 10 studies with 2,313 men give a doctor-measured erect length by region that passed our checks. Many countries have no usable study at all (Epic's review of published size studies).

  • Region averages differ by at most 0.62 inches. That is less than the 1.10 inch gap between home and doctor measurements, so who holds the ruler matters more than where a man lives (Epic's 2026 size data and 10 doctor studies).

Each region combines its studies, weighted by how many men each one measured. Some studies cover only young men, clinic patients or one doctor, so read the rows with care. Every study is linked in our size calculator.

07What Size Women Prefer

Less than most men think.

  • Women picked 6.3 inches long and 4.8 inches around for a long-term partner, in a lab study with 3D models (Prause 2015, 75 women).

  • For a one-time partner the same women picked only slightly bigger, 6.4 inches long and 5.0 inches around (Prause 2015, 75 women).

  • In a street poll by Baseem of Epic Extender, 11 of 14 women said size would not be a deal breaker.

08Can Penis Size Change

Yes, slowly. These are men who trained with an extender or a pump and measured themselves.

  • Experienced users went from an average of 6.26 to 6.88 inches long after 250+ extender hours over 6 months or more (Epic's 2026 size data, 71 men).

  • 90% of men who logged 250 or more hours on a penis extender measured longer than when they started (Epic Traction Report 2026, 81 men).

  • 72% of men with 50 or more pump hours measured thicker (Epic Traction Report 2026, 82 men).

  • 68% of men want more length and more girth, not one or the other (Epic quiz, 18,980 answers).

Method and Limits

Where the numbers come from

  • Epic's 2026 size data. The first measurement each man entered in our PE Trainer app. 11,292 men for erect length pressed to the bone, 7,378 for length not pressed and 10,010 for erect girth.
  • Doctor measurements. Published studies where a health worker did the measuring. Each one is linked next to its number.
  • Percentiles and shares for doctors. We take the average and the spread from Veale 2015 and assume a bell curve. For our own data we count the real men.
  • Regions. Each region combines its doctor-measured studies, weighted by how many men each one measured.

What these numbers cannot tell you

  • Our data is self-measured. Nobody checked the ruler. Men also round to easy numbers.
  • It is not a population average. These are men who chose to train with our devices, and that group may differ from all men.
  • Studies measure in different ways. Some press to the bone and some do not. Compare studies and regions with care.
  • Bell curves get rough at the far ends. Treat the shares for very large and very small sizes as estimates.
  • We sell enlargement devices. Read the numbers with that in mind. We publish the method and the data so anyone can check them.

Penis Size Statistics FAQ

What is the average penis size?

Measured by doctors, the average erect penis is 5.17 inches long and 4.59 inches around (13.12 by 11.66 cm, Veale 2015). Men who measure at home report more. The middle man in Epic's 2026 size data measures 6.26 by 5.00 inches (11,292 men).

What is the average penis girth?

About 4.59 inches around when erect, measured by doctors (Veale 2015). At home, the middle man in Epic's 2026 size data measures 5.00 inches around.

What percentage of men are 6 inches or longer?

About 10% when doctors measure. At home it is more common. 63% of men in Epic's 2026 size data measure 6 inches or more.

What percentage of men have a 7 inch penis?

About 0.2% in doctor studies, or 1 in 400 men. Men who measure at home report it far more often. In Epic's 2026 size data, 22% of men measure 7 inches or more, pressed to the bone.

What percentage of men have an 8 inch penis?

Doctor studies put it at fewer than 1 in 10,000 men. In Epic's 2026 size data, 3.4% of men logged 8 inches or more at home.

Why are home measurements bigger than doctor measurements?

Three reasons. Men measure themselves, most men press the ruler to the bone, and men who track their size are not a random sample. In Epic's 2026 size data the average is 1.10 inches above the doctor average.

Should I press the ruler to the bone?

Yes. It gives the same number every time, because the fat pad no longer counts. In Epic's 2026 size data, pressing added a typical 0.51 inches.

Can I use these statistics?

Yes. Use any number with credit and a link to this page. You can download the data as a CSV file.
