The topic of penis size is often linked to ethnicity and nationality, but how much variation is there between different countries?
An interactive map provides insight into the average size of a man’s erect penis across various nations. The map indicates that there’s a noticeable difference of a few inches between the countries with the largest and smallest average penis sizes.
Even though it’s widely accepted that size isn’t crucial, the subject continues to pique curiosity.
The ongoing commentary from experts on the subject only adds fuel to the fire of public interest.
For instance, a surgeon and sexual health expert has shared insights on which body part might hint at penis size.
Dr. Rena Malik, during her appearance on the Diary of a CEO podcast, debunked the common belief that foot size is related to penis size.

“There’s one study — it’s a Japanese study where they looked at only Japanese men so there are some limitations — but they measured all these body parts and penile length and they found was that nose length was correlated with penile length, not hand length or foot,” Dr. Malik explained.
While further research is necessary, current data suggests significant differences in average penile lengths between countries.
The map data indicates that if you’re seeking the largest average penis size, there are particular regions to consider.
The World Population Review interactive map projects that in 2025, Sudan and DR Congo will share the spot for the largest average penis size, with each boasting an average erect length of 7.1 inches.
The smallest average size is found in Thailand, at 3.7 inches.
Curious about the United States? The map shows the average size in the US is 5.5 inches, while Canada, the UK, and Russia each average 5.6 inches.
The top ten countries by reported average penis size are:
Sudan- 7.1
DR Congo- 7.1
Ecuador- 6.9
Republic of the Congo- 6.8
Ghana- 6.8
Nigeria- 6.7
Venezuela- 6.7
Lebanon- 6.6

Colombia- 6.6
Cameroon- 6.6
On the smaller end of the spectrum, several Southeast Asian countries include:
Thailand- 3.7
North Korea- 3.8
Cambodia- 3.9
Nepal- 3.9
Myanmar- 4.0
Laos- 4.0
Vietnam- 4.0
Sri Lanka- 4.0
South Korea- 4.3
Philippines- 4.3
It is important to note that these figures represent median sizes for each nation and are not indicative of individual measurements.
A separate self-reported survey by Bespoke Surgery explored average penis sizes within the United States.
Findings revealed that Alabama has an average length of 7.44 inches, while West Virginia’s average is 7 inches.
Other states with notable averages include Louisiana (7.15), West Virginia (7.00), Vermont (6.98), Utah (6.97), Oklahoma (6.93), and Alaska (6.92).
These numbers suggest a size significantly larger than that of other states.
Therefore, it’s wise to interpret this data cautiously.
