The World’s Biggest Penis – Matt Barr

Find out more about the real life story of the man with the world’s biggest penis to have been independently verified by multiple independent studies: the most recent recording it at over 36.5cm/14.4 inches long and over 21.5cm/8.5 inches in circumference.

‘A Long Story: Life With The World’s Largest Penis’ (originally titled ‘A Long Story: Life With One Of The World’s Biggest Penises’) 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.
