About Dickle

Dickle is a quick, free browser game you play once a day. Each day you get one country and you try to guess the average penis size published for it, in centimetres or inches. You get five tries, with higher-or-lower hints after each guess, and you win if you land within 0.15 cm. The country changes every day at midnight your time.

If you like Wordle or Globle, this is the same kind of thing: a short daily puzzle and a streak you'll want to keep going. When you're done, you can share your result without spoiling the answer.

There are 24 countries in the rotation. You can see all of them, with their studies, on the countries page. Whichever one is currently in play has its figure withheld.

Because it's a subject discussed constantly and understood almost never. Practically every number in circulation comes from men estimating themselves, which inflates things substantially. The map everyone has seen shades in countries nobody has ever measured. And the industry selling solutions has a direct interest in you never meeting the real distribution.

Meanwhile the actual research is excellent, freely available, and read by almost no one. Two of the largest reviews ever conducted, covering more than 70,000 men between them, land within a few millimetres of each other, and the figure they arrive at is consistently lower than people expect.

A daily game turned out to be a decent way in. You guess, you find out you were wrong, and being wrong is what makes it stick. The 19 guides are the longer version of that argument.

Dickle uses stretched length: the flaccid penis extended to its full length and measured from the pubic bone to the tip. It sounds like an odd choice until you look at the literature. It's the number urology studies report, because a clinician measures it with a ruler rather than relying on self-reported figures, which run notoriously high. It also tracks erect length closely, which is why it serves as the standard clinical stand-in.

Sticking to one measure is the only thing that makes the countries comparable at all. Mixing a self-reported erect figure from one country with a clinician-measured stretched figure from another would tell you about the researchers, not the populations.

The pooled worldwide mean is 12.93 cm, from Belladelli et al., World J Mens Health, 2023 (55,761 men).

Every country in the game is tied to a specific published study, and the reveal screen names it: authors, year, how many men were measured, and the method. Most come from peer-reviewed urology journals: European Urology, BJU International, the International Journal of Impotence Research, Andrologia and others.

Read them loosely. Sample sizes range from about fifty men to several thousand. Some studies press the ruler into the pubic bone and some don't, which alone shifts a figure by a centimetre or more. Several are decades old. And the spread between individual men inside any one country is far larger than the gap between any two countries on this list, so none of this says anything about anyone in particular. Where a figure circulates widely but we could not trace it to a primary study, the site says so rather than dressing it up.

The methodology page sets all of this out properly, including the four specific ways these numbers can be wrong.

It is not medical advice, and it cannot tell you anything about your own body. It publishes population averages from medical literature for general interest and education, with no imagery and no clinical claims.

Distress about penis size in men of entirely normal anatomy is common, well documented in the literature, and treatable. The treatments with an evidence base behind them aren't the ones being advertised to you. If it's something you have been carrying, a doctor is a better next step than a website with a guessing game on it.

Dickle is an independent side project run by one person, Flavius Cojocaru, based in Romania. The same person reads the papers, records each figure with its sample size and measurement method, writes the guides, builds the site and answers the mail.

I build and run Dickle on my own. That means I read the urology papers the country figures come from, record each study's sample size and measurement method alongside its number, write the guides, build the site and answer the mail.

I am not a doctor, and nothing on this site is written as though I were. What I can promise is narrower and more checkable: every figure here names the study it came from, the ones I could not trace to a primary source are labelled as untraced rather than quietly published, and no page here will tell you what your body should look like or sell you something to change it.

Saying that plainly is not modesty, it is the point. On this subject nearly every page competing for the same search has no author, no citation and a product to sell, and the numbers on those pages are mostly invented. A named person who prints the study behind each figure and is wrong in public when a figure turns out to be wrong is the entire difference being offered here.

If you have a question, spot a mistake, or can point us at a better study for a country, email flaviuscojocaru19@gmail.com, find the code on GitHub, or use the contact page. The corrections policy says what happens to a report once it arrives.

A country's figure needs a primary study with named authors, a measurement taken by a clinician rather than reported by the participant, the same measure as every other row, and its method recorded alongside it, including whether the ruler was pressed into the pubic bone. Countries that cannot clear all four are left out of the rotation rather than filled in, which is why this game covers far fewer countries than the maps circulating online.

Nothing that claims to change the number has ever been sold, promoted or paid for placement here, and nothing ever will be. The editorial policy sets out the full test, what we refuse to do, how corrections are handled and how the site is funded.
