About your results

What's the average?

Your measurements are compared to the average values found from the largest scientific studies conducted so far which combines data from twenty one separate scientific studies on penis size involving 16,299 men. The average erect penis from this analysis was found to be 5.48" (13.92cm) long, 4.55" (11.55cm") in girth, and 3.61" (9.16cm) long and 3.67" (9.31cm) girth when not erect. The variation is also smaller than might be expected, with 90% of men falling within just 2" (5cm) of these averages. If you're going to compare, make sure you measure correctly!


Contrary to popular belief, there is little scientific evidence that penis size varies by ethnicity or height, and no strong correlation has been found between penis size and foot or hand size. Length of the flaccid penis does not necessarily correspond to length of the erect penis; some smaller flaccid penises grow much longer, while some larger flaccid penises grow comparatively less (so called growers and showers). Penis size increases during puberty, usually between the ages of 11 and 18, but often continues growing until the age of 21. However, every guy is unique and boys develop at different ages and rates.


Worried you're small?

Nearly half of all men are unsatisfied with or have feelings of inadequacy about the size of their penis. This is perhaps unsurprising given that for many men the only dicks they will see will be their own and those they see in porn. This may give them a very distorted view of where they stand because not only are porn stars selected precisely because they have larger than average dicks, but also because they use camera angles and other tricks to distort the viewers perspective. Similarly, when looking down at your own dick the foreshortening effect makes it look smaller than if you look at another guys from a different angle. It's also worth noting that with regards to sex, most women do not experience orgasms via penetration but by clitoral or other stimulation, so try some different positions and work on your finger and oral skills!


For most men, fears about having a small penis are completely unwarranted and even if you are below the average measurement it's unlikely to be by very much. In fact, the vast majority of men fall within less than an inch either side of the average length. In fact, 90% of men are between 4.35"-6.61" (11.04-16.8cm) in erect length, 3.54"-5.56" (8.98-14.12cm) in erect girth, and 2.59"-4.62" (6.58-11.74cm) in flaccid length. This means that just 5cm separate the bottom of this range from the top! However, if you think you are on the smaller side (particularly in girth), you may benefit from purchasing smaller condoms which may improve sensation during sex and be less likely to slip off.

Worried you're too big?

If you're very large it is possible that you may cause your partner pain or discomfort. If this is the case you may find lube and different positions help you and your partner, as well as taking things a bit slower. Aside from than this, you may also benefit from purchasing larger condoms which may improve sensation during sex and be less likely to break. Use our condom sizer to find out what we'd recommend!
