Meet Matt Barr – The Man With The Independently Verified World’s Largest Penis (2024)

Find out more about the real life story of the man with the world’s biggest penis to have been independently verified by multiple medical studies: the most recent recording it at 36cm/14.2 inches long and 21.5cm/8.5 inch circumference

‘A Long Story: Life With One Of The World’s Largest Penises’ (due early 2025) will tell his story in greater detail.

* The previous scientific record is 27cm (1992, Bondil et. al) – my official measurement by an NHS-affiliated study in March 2024 is 31cm (non-bone pressed) and, more recently for an independent research piece, 36cm (bone-pressed). By this measure it is “the world’s biggest penis” of those that are natural and can maintain an erection. Roberto Cabrera claims almost 19inches but an X-ray proved this was just loose skin, while Jonah Falcon, who claims 13.5 inches, has refused independent verification (and I would happily challenge him for the title directly). Guinness does not track penis size records, while the World Record Academy requires a £25k payment. If you know of any upcoming authentic studies in which I can take part, please get in touch.
