About 13.6 cm erect. Chen 2000 induced erections pharmacologically in 55 patients and measured them, which is methodologically among the strongest things anyone has done in this literature and among the smallest. The claimed 14.4 cm overshoots the only real Israeli measurement by 0.8 cm.
The claim runs 0.80 cm above the measurement, and both are erect measurements, so the gap is not an artefact of measuring different things.
What was actually measured in Israel?
Pharmacologically induced erections are the gold standard here, and hardly anyone uses them. An intracavernosal injection produces a full, reproducible erection that a clinician can measure with a ruler, removing both the self-report problem and the stretched-versus-erect problem in one move. Saudi Arabia's entry in this register uses the same method on 778 men. Israel's uses it on 55.
Fifty-five is small enough that the confidence interval swallows the disagreement. The standard error on 55 men is about 0.23 cm, so the 95 % interval runs roughly from 13.15 to 14.05 cm. The claimed 14.4 sits outside it, but not by much, and anyone insisting on the difference is over-reading both numbers.
The sample is also patients rather than volunteers, which is the standard caveat, and Belladelli 2023 checked that specific worry across 75 studies and found no significant difference between the two groups. The size of the sample is the real limit here, not who was in it.
How does that compare with the rest of the world?
The claim puts Israel 73rd of 119 countries on the ranked list. Here is that number set against the figures that come with a method attached.

. Belladelli 2023.
That last interval is 3.11 cm wide,
for a whole continent, from the largest meta-analysis there is. The claimed map it sits
under spreads all 119 countries across
7.9 cm and prints every
country to one decimal place. Read those two sentences together and you have the
entire problem with penis size by country.
How many men does the claim cover?
55 measured → 3,300,000 described
55 men in Israel appear in the studies this register could locate. The claimed figure is applied to roughly 3,300,000 adult men: one measured man for every 60,000.
Where would you land in Israel?
Against the claimed figure, because that is the number people mean when they ask. It
is the weaker of the two numbers above, and the calculator says so. Everything is
computed in your browser and nothing you enter is stored or sent anywhere.

What should you take from this?
Israel has the right method and not enough men. Read it as roughly 13.6 cm erect with real uncertainty around it, which puts it within half a centimetre of the pooled clinical world figure, like almost every properly measured country in this register.
The countries that look extreme on the map are not the ones measured this way. They are the ones not measured at all.
Nearby in the register
The nearest countries with an entry of their own here.
Nearer still, and with nothing to show: Syria, Armenia, Georgia. Those
countries carry a claimed figure on every map and no located study behind it, so they
have no page here. The method page lists all of them.
