Celebrity & Athlete Heights
Lionel Messi's height is almost always brought up in the same breath as a remarkable medical backstory: a childhood growth hormone deficiency that could have ended his career before it began. This guide covers exactly how tall he is, the real story behind that diagnosis, and an up-to-date look at his career, family, and the 2026 World Cup run that may have been his last.
Messi's height is sometimes listed as 1.69 m (5 ft 6 in), but his official club profile at Inter Miami and Transfermarkt both currently list 1.70 m (5 ft 7 in), which this article uses as the primary figure. His weight has also fluctuated over his career; reports have described periods in his teens when it rose to around 77 kg before he adjusted his diet and training, and it's currently reported at around 67 kg.
The Growth Hormone Deficiency Story Behind His Height
Messi began playing football at age four with Grandoli, his first club in Rosario, before moving to Newell's Old Boys, where his father served as one of his early coaches. Around age 10-11, doctors in Rosario diagnosed him with growth hormone deficiency (GHD), a condition in which the pituitary gland doesn't produce enough growth hormone to support normal development. At the time, he reportedly stood around 1.27 m (4 ft 2 in), noticeably smaller than other children his age, and doctors estimated that without treatment, he might reach an adult height of only around 1.40 m (4 ft 7 in).
Treating GHD requires daily injections of synthetic growth hormone, typically continuing for years until the growth plates close, and the therapy was expensive: reports place the cost at roughly $900 to $1,000 a month, far beyond what his family could sustain long-term on their own. Newell's Old Boys contributed some support, but not enough to fund the full multi-year course of treatment. That changed in September 2000, when a family connection in Catalonia led to a trial with FC Barcelona. The club was reportedly impressed enough by his skill that a preliminary agreement, according to a well-known story, was written out on a paper napkin. Messi officially joined Barcelona's La Masia academy at 13, with the club agreeing to fund the remainder of his GHD treatment as part of the arrangement.
GHD is typically managed, not cured. Because growth hormone deficiency is usually a lifelong condition that's managed rather than eliminated, people diagnosed as children are generally reevaluated as adults to see if treatment is still needed. Messi has never spoken publicly about requiring ongoing treatment as an adult, and his decades-long career at the top level of professional football suggest the childhood therapy successfully addressed its impact on his physical development.
Career Biography
Major Individual Achievements
A World Cup final, and possibly a farewell. Messi and Argentina reached the 2026 World Cup final, aiming to become the first team to win back-to-back titles in 64 years. Spain won 1-0 in extra time on a late Ferran Torres goal, denying Argentina the title and ending the tournament with a runner-up medal for Messi, who has said this is likely to be his final World Cup; he would be 43 by the time the next edition arrives in 2030.
Personal Life
Messi is married to Antonella Roccuzzo, also from Rosario, whom he has known since childhood through mutual family connections. The couple began dating in 2008, confirmed their relationship publicly in 2009, and married in 2017. They have three sons together: Thiago (born 2012), Mateo (born 2015), and Ciro (born 2018). Roccuzzo, whose family runs a business in Rosario, has largely stayed out of the public eye aside from accompanying Messi to matches and events.
The bottom line: Lionel Messi's height, at 1.70 m, is unremarkable on its own, but the story behind it — a childhood growth hormone deficiency that a napkin-written Barcelona contract helped resolve — is part of what makes his career so widely told. Between a record eight Ballon d'Or awards, a 2022 World Cup title, and a runner-up finish in what may have been his final World Cup in 2026, his height was never the story. What his family and Barcelona did about it, arguably, was.

His official Inter Miami and Transfermarkt profiles list him at 1.70 m (5 ft 7 in), though some older sources cite 1.69 m (5 ft 6 in).

Who paid for Messi's growth hormone treatment?
His family covered what they could, with some early help from Newell's Old Boys, but the full cost wasn't sustainable long-term. FC Barcelona agreed to fund the remainder of his treatment as part of the contract that brought him to their youth academy at age 13.
