Measured studies find a clear central tendency: average erect penile length is roughly 13.1 cm (≈5.1 in) and average erect circumference about 11.7 cm (≈4.6 in), with most men falling within a tight b...
Percentiles for penis girth are calculated by comparing a measured circumference to distributions compiled from population studies and treating that distribution as a statistical curve (often assumed ...
Available data assembled by analysts such as Data Pandas and Visual Capitalist places the global average erect penis length between about 12.9–13.9 cm (5.1–5.5 in) with many country-level compilations...
Recent systematic reviews and large compilations put the global average erect penis length in the mid‑teens of centimetres: many clinical meta‑analyses report roughly 13.1 cm (5.16 in) to about 13.9 c...
Global studies converge on a modest range for average erect penis length — roughly 13–14 cm (5.1–5.5 in) — but published country-by-country rankings vary because of different data sources, measurement...
Major, peer-reviewed syntheses and clinical studies put average adult penis size in a narrow range: erect length about 13.1 cm (≈5.1 in) and flaccid length roughly 9.16 cm (≈3.6 in) based mainly on la...
Research and popular reporting show modest regional differences in average penis measurements but large overlap across populations; global averages cluster around ~13–14 cm erect while some country‑le...
Measured studies and large reviews put the global average erect penis length at about 13.1–13.9 cm (≈5.1–5.5 in) and erect girth/circumference around 11.66–12.0 cm (≈4.6–4.7 in), while flaccid average...
Peer-reviewed measurements cluster tightly: pooled meta-analyses place mean erect length around 13–14 cm and stretched lengths around 13 cm, with the largest measured erect values in the literature ge...
Multiple academic systematic reviews and meta-analyses synthesize raw studies of penile measurements, while several public “country-by-country” compilations (DataPandas, WorldData, VisualCapitalist, W...
Scientific measurements show average erect penis circumference (girth) is about 11.7–12.0 cm (4.6–4.7 in) in large, provider‑measured studies; flaccid girth averages nearer 9–10 cm (3.5–3.9 in) . Stud...
An erect penis of 18.2 cm BPEL length and 15.0 cm girth lies well above common medical averages: most large reviews put mean erect length around 13.1–13.8 cm and mean erect girth around 11.7–12.0 cm, ...
Major sexual-health studies and systematic reviews generally define “very large” or “large” penises relative to population distributions rather than fixed cutoffs: most clinical papers report mean ere...
Peer‑reviewed, clinician‑measured studies that break down penis size by U.S. racial or ethnic groups are sparse and disputed; large reviews and authoritative summaries report little or no meaningful d...
The 2015 systematic review by Veale et al. reported a based on direct measurements from 692 men; this figure is the most-cited value from that study and appears across multiple secondary summaries . S...
Available aggregate rankings list Venezuela among the countries with higher reported average erect penile length (around 16.7–16.9 cm), but the publicly available secondary sources in this packet do n...
A person with an erect penis 8.125 inches long is astronomically rare by published nomograms: using the standard‑measurement literature that places 6.3 inches at about the 95th percentile, an 8.125‑in...
Wessells et al. (cited across reviews) are a frequently referenced primary source on penile measurement methods and normative data, and later meta-analyses and systematic reviews report regional/ethni...
Recent 2025 compilations place the global average erect penis length between roughly 12.9–13.9 cm (5.1–5.47 in): Medical News Today cites a commonly used clinical mean of 12.9 cm (5.1 in) , while at l...
The most-cited, rigorously pooled global estimates come from systematic reviews and meta-analyses that include clinician‑measured data rather than self‑reports: a 2024–25 systematic review by Mostafae...
