What are the average and median erect penis lengths by country or region?
Executive summary
Multiple recent compilations and a systematic review place the global average erect penis length in the mid‑teens of centimeters: Data Pandas / DataPandas-derived sites report a global mean around 13.1–14.1 cm (5.16–5.54 in) [1] [2], while a peer‑reviewed systematic review gives an overall mean erect length of about 13.84 cm from clinically measured studies across WHO regions [3]. Country rankings vary widely across aggregators: some datasets place Ecuador near 17.6–17.9 cm and list several African and Latin American countries near the top, while East and Southeast Asian countries typically report lower averages around 10–11 cm in these compilations [1] [4].
1. What the main sources say — headline numbers and top countries
Aggregated online datasets produced in 2024–2025 (Data Pandas and sites that republish its data) put the worldwide average erect penis length at roughly 13.12 cm (5.16 in) to about 14.08 cm (5.54 in), depending on methodological adjustments applied to self‑reported data [1] [2]. Those compilations consistently place Ecuador, Cameroon and some South American and African countries near the top (Ecuador reported ~17.59–17.61 cm in several outlets), and East/Southeast Asian countries among the lower averages (some reported near or below ~10.0–10.9 cm) [1] [5] [4].
2. Peer‑reviewed perspective — clinical measures and regional means
A systematic review and meta‑analysis that pooled studies up to February 2024 reports mean erect length across included clinical studies of about 13.84 cm and provides regional breakdowns by WHO region, with the Americas showing larger stretched/flaccid values in that dataset (and the largest mean stretched length of 14.47 cm reported for “Americans”) [3]. That meta‑analysis intentionally emphasises professionally measured data rather than self‑reports to limit bias [3].
3. How measurement method changes the story
Compilations that combine self‑reported surveys with clinical measurements apply statistical corrections and say those adjustments materially alter rankings and the global mean: Data Pandas reports a corrected global average of 13.12 cm after standardising self‑measurements [1]. The systematic review restricted to clinician‑measured studies yields a similar but not identical mean (~13.84 cm), underscoring that measurement technique—self‑report versus clinician measurement—shifts country and global numbers [3] [1].
4. Limits and biases in the data — why country rankings are unstable
Available sources repeatedly warn about methodological limitations: many country values derive from small samples, self‑measurement, or mixed‑quality surveys; some aggregators explicitly adjust for bias, others do not [6] [1] [7]. The systematic review limited inclusion to studies with healthcare‑professional measurements to reduce these biases, which improves reliability but reduces country coverage and can change rankings [3].
5. Regional patterns — what appears consistent across datasets
Across multiple compilations, continental and regional patterns recur: Latin America and parts of Africa appear more often near the higher end of reported averages, while East and Southeast Asia more often appear near the lower end. Compilers caution these are trends in aggregated data, not proof of discrete biological categories, and differences are often smaller than popular myth suggests [1] [6] [4].
6. What the numbers do and do not prove — interpretation and social context
Sources stress that country averages do not equate to meaningful health or social value: clinical literature defines medical micropenis at under ~7 cm when erect, a threshold absent from most country lists [1]. The datasets also point to psychological consequences: surveys note widespread body‑image anxiety linked to unrealistic portrayals in media and pornography, which skew perceived norms [3] [1].
7. Practical takeaway for readers seeking country or regional data
If you need a defensible, clinically grounded regional estimate, refer to the systematic review’s region‑level means (~13.84 cm overall for erect length from clinician‑measured studies) [3]. If you are examining detailed country rankings, use the Data Pandas compilation and its republications (and remember those values include corrected self‑reports and vary by methodology; global mean reported there is ~13.12 cm) [1] [8]. Treat precise country ranks with caution because sampling, measurement method, and small sample sizes drive many of the differences [1] [7].
Limitations: available sources do not mention consistent median values by country (median statistics are not reported in the cited compilations or the systematic review), and many outlets rely on mixed methodologies, which makes single‑number country claims fragile [1] [3] [6].
