Executive summary

There is no Guinness World Record entry for the longest human penis; Guinness’s publicly searchable records do not list a human penis size record and their animal-penis record refers to non-human species (blue whale) rather than people [1] [2]. Independent and contested claims exist — most notably Jonah Falcon’s long-standing public claim, Roberto Esquivel Cabrera’s widely reported claim, and a more recent medically reported verification for a man named Matt Barr — but none of these are listed as a Guinness World Record [3] [4] [5].

1. Guinness’s position: no official human-penis world record in the public database

A search of Guinness World Records’ public site and record search tool shows entries for animal penises (the blue whale holding the absolute longest animal penis at up to 2.4 m/8 ft) and other categories, but does not provide a Guinness-sanctioned record for the longest human penis in their searchable listings, indicating that Guinness does not maintain a publicly available human-penis size title on its site [2] [1].

2. The perennial headline names and why they differ

Jonah Falcon became the most famous claimant after media attention in the late 1990s and onwards; he claims an erect length of 13.5 inches (34 cm) but “has not authorized or permitted independent verification of this figure,” which prevents that claim from becoming an independently verified record [3]. Roberto Esquivel Cabrera has been reported to claim an appendage of roughly 18.9 inches and was at times labeled by non-mainstream record sites like the World Record Academy as a record-holder, but such announcements have not won broad medical or institutional verification and have been disputed in coverage [4].

3. A 2024–2025 claimed medical verification — Matt Barr — and its limits

Several sources oriented around penis-size documenting communities report that a man named Matt Barr was medically measured and independently verified by medical professionals, with reports citing measurements of roughly 14–14.5 inches (37 cm) and follow-up coverage around 2024–2025 describing multiple independent confirmations and a book recounting his story [5]. Those accounts present Barr as the “world’s biggest penis” among men who have undergone formal medical verification, but these are not Guinness World Records entries and rely on non-Guinness outlets and niche sites for their claims [5].

4. Why no single, uncontested “Guinness” answer exists

Three separate dynamics explain the lack of a clear Guinness answer: Guinness’s public database does not list a human-penis category [1]; high-profile claimants like Falcon have refused independent verification making their numbers unverifiable under scientific or record-keeping standards [3]; and other claimants (e.g., Cabrera) have had their claims questioned on medical grounds, with some reports attributing apparent length to excess foreskin or other non-standard measures [4] [5].

5. How to weigh competing claims and what “verified” means here

“Verification” in this context can mean different things: an appearance in a mainstream institution’s published record (which does not exist for human penis length at Guinness, p1_s5), a medical measurement by independent clinicians (as reported in the case of Matt Barr by certain outlets, p1_s4), or acceptance by smaller record organizations or media (as with Roberto Cabrera’s coverage by World Record Academy, p1_s6). Because the sources use different standards and because Guinness does not publicly maintain this human category, no single claimant can be said to “hold the Guinness World Record” for longest penis at any verified date based on the available reporting [1] [3] [5] [4].

6. Bottom line

Guinness World Records does not currently list a human longest-penis record in its public database, so no one “holds the Guinness World Record” for the longest human penis according to that organization’s searchable records [1] [2]. Independently verified medical claims (e.g., reporting around Matt Barr) exist in other outlets, while longstanding public claimants such as Jonah Falcon and publicity-driven claims such as Roberto Esquivel Cabrera remain disputed or unverified by mainstream record institutions [5] [3] [4].
