Data for Italy
Italy is one of the countries with a peer-reviewed regional study: Ponchietti et al. (2001). Eur Urol, 39(2), 183-186., with a sample of 3,300 men. The reported average erect length was 12.5 cm (4.92 inches), compared to the global pooled average of 13.12 cm from the Veale et al. (2015) BJU International meta-analysis.
That difference of 0.62 cm is within typical between-study variation — single-country samples tend to drift by small amounts depending on measurement protocol and participant recruitment. You can read the abstract at https://pubmed.ncbi.nlm.nih.gov/11223678/.
Why country averages are less useful than percentiles
Between-country variation in the scientific literature is small compared to within-country variation — the standard deviation inside any single country is larger than the differences between countries. That is why the percentile calculator above is more useful than a country-mean comparison: it tells you where you stand against the full global distribution, which is what actually matters.
