It is perhaps one of the biggest mysteries surrounding the world of men. The answer to the question of which penis size women actually prefer divides opinion. Funnily enough, this discussion is often led by men without involving women. A study has now finally provided scientifically sound answers. We have summarized everything you need to know.
Aim of the study: What erect penis size do women prefer for long-term partners and one-night stands?
The study conducted is the first study on the topic of perfect erect penis size from the perspective of women. Previous studies examined women’s preferred flaccid penis size, but this one focused on the ideal erect size. It also explored differences between long-term partners and one-night stands. Seventy-five women of various ages determined the ideal erect size using 3D penis-like models.
How did the study work?
The women were not selected for the study, but actively applied to take part. It was required that they be heterosexual and over 18 years old. The participants were not only allowed to look at the penis-like models, but also to touch them. In addition to physical contact with the models, they also had to answer 15 questions about the perfect penis size. The determination of the ideal erect penis size was therefore not only based on mental estimates or memories of past sexual partners.
In addition to interesting results on the ideal length and thickness, the study also identified different preferences between one-night stands and permanent partnerships..
Women want more than the average
The study shows that women in a steady relationship prefer an average erect penis length of 16 cm and an average length of 16.3 cm for one-night stands. According to the participants, the perfect circumference of an erect penis is 12.2 cm for a steady partner and 12.7 cm for a one-night stand.
Compared to the global average, men are therefore a good four centimetres short.
Penis length is not equal to penis length: it depends on the measurement method
There are two different measurement methods for determining the erect penis length, which are very similar but can lead to very different measurement results. The erect penis can be measured using either the NBPEL or the BPEL method.
With the None-Bone-Pressed-Erect-Length (NBPEL), the measurement is only taken on the visible part of the penis. The measuring device is not pressed up to the pubic bone, but is only applied to the abdominal skin above the abdominal fat layer. This results in shorter measurement values than with the Bone-Pressed-Erect-Length (BPEL). This is because the part of the penis that is not visible and is covered by the abdominal fat layer is also measured by pressing the measuring device onto the pubic bone. The total or actual erect penis length is therefore measured.
Visible or total erect penis length
The women in the study stated that the perfect erect penis should be between 16 and 16.3 cm long. If you wanted to measure your own penis for comparison, this value corresponds to the measurement using the NBPEL method, as the women only assessed the visible or tangible length of the penis by looking at and touching the penis models. In almost all studies, however, the erect penis length is determined using the BPEL method. This is because the BPEL method is the most accurate measurement method for determining the erect penis length. Measuring from the pubic bone means that the “whole” penis is measured and, because the position of the pubic bone in the body does not change, significantly fewer measurement errors are made.
In order to be able to compare the ideal erect penis length from this study with the average erect penis length from other studies, a corresponding correction must therefore be made to bring the BPEL and NBPEL methods into line.
NBPEL = BPEL – Abdominal Fat Layer
An erect penis with an ideal NBPEL of 16-16.3 cm corresponds to a BPEL of at least 16.5-17.3 cm, as BPEL measurements are typically 0.5-1 cm longer, depending on the thickness of the abdominal fat layer.
Written as a formula:
BPEL = NBPEL + Abdominal Fat Layer
NBPEL = BPEL – Abdominal Fat Layer
The thicker the abdomen, the shorter the penis appears
The higher the body fat percentage, the thicker the abdominal fat layer usually is. And the thicker the abdominal fat layer, the shorter the penis. Don’t worry, the penis doesn’t actually shrink when the abdominal girth increases, it’s just hidden by it. Even with daily gym workouts and a perfect diet, belly fat is at least 0.5 to 1 cm thick. Thus, the NBPEL method cannot determine the true erect penis length 100% as part of the penis is always covered by abdominal fat. It only measures the visible erect penis length not hidden by the fat layer, regardless of how slim you are.

Ideal and average erect penis size in comparison
The actual erect penis length can therefore only be measured using the BPEL method. This method was used in the largest meta-study on global penis size, as reported in our other article. Comparing studies without considering differences between BPEL and NBPEL methods would distort results. Women judged their ideal penis size based on visible or perceptible length, aligning with the NBPEL method. And, as already explained, this is always smaller than the BPEL method. For many men, this would be the second piece of bad news we have to deliver. This is because the average erect penis worldwide is up to 4 centimetres short of the ideal length for women.
Ideal erect penis length (NBPEL) = 16-16.3 cm ≙ BPEL of at least 16.5-17.3 cm.
Average erect penis length according to the largest study (BPEL) 13.12 cm.
When it comes to the circumference of the erect penis, the average and ideal measurements are not quite so far apart. According to the study, the ideal girth should be between 12.2 and 12.7 centimeters. On average, men reach 11.66 centimeters, which is only a maximum of one centimeter below the ideal.
How can the result be interpreted?
The fact is that women indicate a significantly longer erect penis than the average as the ideal size. Women prefer slightly larger-than-average girth, though not as much as length. Interestingly, they favor larger penises in short-term flings or one-night stands over long-term relationships. This may be because a larger penis can compensate for the lack of emotional connection often crucial for women to orgasm during one-night stands. The lack of mental stimulation is therefore compensated for by increased physical stimulation. For more precise correlations, however, more information would have to be collected and further studies conducted.
How conclusive is the study?
The study has so far only been conducted with 75 women. Most of them were from California, which is why there is still no real significance with regard to global preferences. However, this first study could already be a good indicator that reality and perfection do not always meet between a man’s legs. But men, don’t worry. When it comes down to it, even after this study, only very few women will take out a ruler to measure your best piece. Because of course, even after this study, the penis is only one part of the big picture.
