A study was once conducted to answer a question that has perplexed men for millennia.

What do women consider to be the ideal penis size for a partner?

This groundbreaking and vital piece of research asked women to make their choice based on two scenarios - one-night encounters and long-term relationships.

The results sparked a conversation about sexual preferences and modern dating expectations.

In reality, there is no 'perfect' size - we're all different, right? - and the scientists behind it warn that preferences vary widely and context matters.

But that's not what you're here for, is it?

The perfect penis size - according to the women surveyed

So, what did the study actually find?

For casual hookups, women on average chose a model measuring 6.4 inches (16.3 cm) in length and 5.0 inches (12.7 cm) in girth.

For long-term relationships, the preference shifted slightly to 6.3 inches (16.0 cm) in length and 4.8 inches (12.2 cm) in girth.

The differences were modest, showing that context influences what women find attractive, but extreme sizes were rarely chosen.

The study emphasizes that while these numbers are above the statistical average, they are far from 'ideal' for everyone.

Scientist warns against 'perfect' label

Dr. Nicole Prause, who spoke to Vice, urged caution in calling any penis 'perfect'.

She explained: “Please don’t call any penis the perfect penis.”

Prause said the research is more about exploring variation than dictating an ideal.

Women’s preferences shift depending on the situation, the relationship type, and individual differences.

“Situational context matters,” she said, adding: “What someone prefers for a one-night stand may differ from what they prefer in a long-term partner.”

What the study actually measured

You might be wondering exactly how this study worked, and - to be honest - you might also have expected it to contain loads of men, and their penises.

Unfortunately, you'd be wrong.

Researchers presented women with 33 different 3D models to pick their ideal partner for casual and committed scenarios.

Most women recalled the models accurately, though some slightly underestimated the length compared with the girth.

The small differences in preference illustrate that while certain sizes are more commonly chosen, variation is significant.

Individual tastes, sexual compatibility, and relationship dynamics often outweigh simple measurements.

The study also shows that the idea of a 'perfect penis' is largely a social construct.

It’s more useful to focus on mutual satisfaction and comfort rather than strict numbers.

Just be a decent dude, and use what you've been given - size doesn't really matter that much.

A YouTuber was left surprised after asking 20 women to reveal what they considered the "perfect" manhood size for a long-term relationship.

Baseem and his co-host, Rosa, interviewed women from several countries, including Australia, Myanmar, Thailand, and the UK, asking them to select their ideal size from a range of models.

Despite the common assumption that bigger is always better, the results suggested otherwise.

The most popular choice was the C2 model, measuring 6.3 inches (16 cm) in length and 5.0 inches (12.7 cm) in girth. Four of the 20 women selected that option.

Three women chose the smaller A2 model, which measures 4.7 inches (11.9 cm) in length and 5.0 inches (12.7 cm) in girth.

Meanwhile, two women selected the slightly larger C3 model, measuring 6.3 inches (16 cm) in length and 5.4 inches (13.7 cm) in girth.

Only one woman chose the D1 model, the largest option available, which measured 7.0 inches (17.7 cm) in length and 4.4 inches (11.1 cm) in girth.

Overall, the women tended to choose sizes that were close to the average.

Answers changed when women were asked about one-night stands

The women were also asked whether their preferences would change for a one-night stand.

Some said their choices remained the same, while others admitted they would opt for something different.

One woman from Sydney said she would still choose a smaller size. Meanwhile, a woman from the UK who had previously selected a smaller size for a long-term partner said she would choose a larger manhood for a casual encounter.

Most women said size wasn't a relationship deal breaker

The YouTuber also asked participants whether penis size would be a deal breaker in a relationship. The majority said it would not.

Of the women surveyed, 11 said size would not affect whether they stayed with a partner, while only three said it would.

One woman from the UK explained: "No, it wouldn't be a deal breaker, no. I think that I think as you get older, you realize that like bigger isn't always better."

Another participant added that some men may have skills to "make up" for it.

Research suggests size isn't the most important factor

The survey findings align with previous research, which suggests that size is often less important than many people assume.

A 2014 review that analyzed data from 15,521 males found an average erect length of 13.12 cm (5.17 inches), while a separate 2014 study involving 1,661 males reported an average length of 14.15 cm (5.57 inches) and an average girth of 12.23 cm (4.81 inches).

Researchers have also noted that self-reported measurements tend to be larger than measured averages.

One 2019 study discovered participants reported an average length of 6.62 inches (16.81 cm), significantly higher than figures recorded in clinical studies.

Experts say preferences vary from person to person and can depend on a range of factors, including sexual comfort and pleasure, individual needs, and personal perceptions.

When it comes to sexual satisfaction, size isn’t just a punchline—it’s a hot-button issue with some serious relationship implications.

A survey of 1,387 women, conducted by sexual health site Bad Girls Bible, has shed light on exactly what women think about penis size—and the results might surprise you.

The survey found that more than two-thirds of women are unlikely to be fully satisfied with a partner whose erect penis is less than four inches.

But there’s a limit to how much is too much. Over half of the women said they found anything over nine inches too large, citing pain, rushed orgasms, and even “sexual selfishness” as common issues with well-endowed partners.

Pain was a recurring theme, with larger sizes causing vaginal bruising, tearing, and discomfort. On the flip side, those who enjoy bigger sizes mentioned “the feeling” as their primary reason for preference.

So, what’s the sweet spot? The researchers pinpointed the ideal range between six and eight inches, with 7.2 inches being deemed the best size.

This range left 77% of women fully satisfied. Interestingly, nearly nine in 10 women preferred a seven-inch length, and two-thirds said both length and width were critical to sexual satisfaction. The average preferred girth was two inches, slightly above the national average of 1.8 inches.

For perspective, the width of a standard golf ball is 1.7 inches.

Size isn’t just a factor in physical pleasure—it can influence relationships, too.

The survey revealed that 44% of women consider a man's size before deciding to date them. Additionally, two-thirds of women said they’d consider breaking up with a partner whose size didn’t meet their needs.

It’s not just small sizes that can cause issues. Nearly 60% of women said they’d break up with someone whose penis was too large, and four in 10 admitted they might cheat on a partner if his size was too small.

For casual hookups, size still plays a role. Just under half of the women said it matters for one-night stands, while over two-thirds said it’s important in a “friends with benefits” arrangement.

For men feeling the pressure to measure up, there’s some good news. Foreplay and a partner’s gentleness were named as key factors in women’s satisfaction, regardless of size. In other words, skill and attentiveness can make up for anatomical shortcomings.

The survey also highlighted that extremes at both ends of the spectrum are rare but impactful. Women were least satisfied with penises measuring between one and three inches, a condition known as micropenis, which affects just one in 10,000 men in the US. At the other end, over nine inches proved too much for more than half the respondents.

Interestingly, one in 200 women said even a one-inch penis was too big. Researchers noted this might reflect the views of homosexual women or those with conditions like vaginismus, where the vaginal muscles involuntarily tighten during penetration.

The findings highlight how penis size can affect more than just physical pleasure. For many women, size plays a role in emotional and physical compatibility, influencing everything from dating decisions to long-term relationship stability.

Ultimately, while size matters to some degree, the survey also shows that communication, effort, and emotional connection remain key components of a satisfying sex life.

So, whether you’re above average, below, or somewhere in the middle, remember that the best lovers prioritize their partner’s overall experience—inside and outside the bedroom.

A new study has revealed the "best penis size" to make a woman orgasm.

Now, as much as reading this will no doubt pain many men, it turns out that size really does matter when it comes to what you're packing downstairs.

Big One Dating asked 4,761 women about the last time they had sex, and specifically, these two questions: How big was he? Did you climax?

Earlier this year, Bear Grylls flashed his penis during a live stream fail: 

[[jwplayerwidget||https://content.jwplatform.com/videos/Rtl5BXXV-dkXnENEs.mp4||Rtl5BXXV]]

So, what's the magic number we hear you ask? Eight inches. To put that into context, that's a penis that's roughly the size of an A4 sheet of paper.

According to the study, that was the magic number that made 44% of surveyed women orgasm.

However, as the chart below demonstrates, while bigger is better when it comes to penis size, it does taper off after a point, and an 11-inch penis was successful at making women orgasm 30% of the time - the same rate as a four-inch penis.

But it's bad news if you've got a one-inch penis, as men of this size only managed to make women orgasm 18% of the time; however, those with three-inch manhoods made over a quarter of women orgasm.

Participants of the survey were quick to stress that while size does matter to an extent, it's no use having a sports car if you don't know how to drive it...

"Penis size is important, but knowing how to work it and wanting to please her trumps over anything else," a 37-year-old participant from New Orleans said.

Meanwhile, a 38-year-old woman from Harrow, England, added: "Size does help but you definitely need to know how to use it. Plenty of wasted big d**k out there."

So if you're on the slightly less well-endowed side, don't sweat it. Skill counts for a lot too.

If you were to have asked the Greco-Roman empire, a small phallus was idealized, considered to be a symbol of intellect and high societal status. Now, however, the modern era is fixated on truncheon-esque penises as a sexual weapon, emblematic of ultimate masculinity. But does the length and girth of these venereal vehicles really matter?

While many, including a raft of healthcare professionals, insist it is merely an irrelevance, the reality is that plenty of men care about it, often comparing themselves to unrealistic expectations.

What is the average penis size?

But according to Dr Karan Rajan, the truth is far less extreme than most would assume, and it might come as a relief to those concerned about the scale of their manhood.

Referencing a major 2014 study, he joked that some “rogue scientists had the balls to conduct a census” on penis size, producing results that challenge common myths. The research, carried out by a team at King's College London, measured around 15,000 men globally in an effort to create accurate size benchmarks and ease anxiety on this divisive topic.

Sharing the findings, he said: “The study revealed that the average length of a flaccid penis was 3.6 inches and the average length of an erect penis was 5.165 inches.”

For many, that figure is lower than expected, largely because of distorted perceptions. As Dr Rajan explained, “Societal expectations, warped by pornography, Hollywood, rumors and overzealous exaggeration, leave most men thinking the average penis is closer to something like 6 inches.”

He added: “Most men regrettably assume they are smaller than average and this distortion fuels a negative self-perception of the body.”

What is the 'ideal' penis size according to women?

Separate data has even ranked average sizes globally, though experts stress that numbers alone don’t tell the full story. What people are often more curious about, however, is what’s considered “ideal.”

One study asked women to choose preferred sizes in two different scenarios, casual encounters and long-term relationships, and the results showed only slight differences. For one-night stand situations, the average preference was around 6.4 inches in length and 5.0 inches in girth, while long-term partners came in just below that at 6.3 inches and 4.8 inches, respectively.

Despite the headlines, experts are keen to stress there is no universal “perfect.”

Nicole Prause warned against labelling any size as ideal, saying: “Please don’t call any penis the perfect penis.”

She added that the research is more about understanding variation than setting a standard, noting: “Situational context matters,” and explaining that “What someone prefers for a one-night stand may differ from what they prefer in a long-term partner.”

Ultimately, while the numbers may grab attention, the takeaway is simple — averages are often lower than expected, preferences vary widely, and there’s no single definition of “perfect.”
