By Low Key NBA , updated

olivier rioux tall nba prospect

Olivier Rioux is a 7-foot-9 Canadian center at UC Irvine and the tallest player in NCAA basketball history. Born in February 2006 in Terrebonne, Quebec, he was certified by Guinness World Records as the world’s tallest teenager at 15. He spent two seasons at Florida, redshirting through the Gators’ 2025 national title run and playing 16 minutes in 2025-26, then transferred to UC Irvine in April 2026.

The question everyone asks is whether he will make the NBA. The honest answer, with the numbers, is below.

How tall is Olivier Rioux?

Olivier Rioux’s height is 7 feet 9 inches, or 236 cm, on both the Florida and UC Irvine rosters. No one taller has ever played college basketball: he passed Kenny George of UNC Asheville (7’7″) and Paul Sturgess (7’8″). FIBA, which measures players for international events, listed him at 233 cm (about 7’7″) at the 2025 U19 World Cup, so the exact number depends on who did the measuring. His wingspan and standing reach have never been published.

How tall was Olivier Rioux as a kid?

He has been very tall from the start. Rioux was 6’1″ at age 8 and passed 7 feet around age 12. Guinness World Records measured him at 226.9 cm (7’5.33″) at 15 and named him the tallest teenager in the world in September 2021.

How tall is Olivier Rioux barefoot?

No barefoot measurement of Rioux has been published since he was 15. The one formal measurement on record is Guinness World Records’ 226.9 cm (7’5.33″) in 2021, taken without shoes. The 7’9″ on the Florida and UC Irvine rosters is a listing, and the rosters do not say whether it was taken with or without shoes. FIBA’s 233 cm (about 7’7″) at the 2025 U19 World Cup sits between the two.

Is Olivier Rioux still growing?

There is no public sign that he is. His listed height has been 7’9″ on every roster since he arrived at Florida in 2024, and neither Rioux nor his coaches have said he is still growing. Most young men reach their adult height in their late teens, and Rioux turned 20 in February 2026. The jump that made headlines came earlier: from 7’5.33″ at 15 to a listed 7’9″ at 18.

Olivier Rioux vs the tallest NBA players ever

If Rioux reached the NBA he would be the tallest player in league history. The current record holders, Gheorghe Muresan and Manute Bol, were both 7’7″. Rioux is two inches taller than them and five inches taller than Victor Wembanyama’s official listing.

Olivier Rioux next to a normal person

Next to an average American man (5’9″), Rioux is about two feet taller. He is about 14 inches taller than the average NBA player and 5 inches taller than Victor Wembanyama. Photos of him standing next to teammates and fans are a big part of why he went viral as a teenager.

Why is Olivier Rioux so tall?

Rioux’s own answer, to CNN in 2024: “We’re still not 100% sure why I’m so tall… doctors could only explain it with the genetics that my family has.” He added, “This is what nature planned for me. I learned to be peaceful and happy about it.”

The family numbers back that up. His father, Jean-François Rioux, is 6’8″; his mother, Anne Gariépy, is 6’1″ or 6’2″ depending on the source; both played volleyball. His older brother Émile was 6’9″ at 15. Height is about 80% inherited, according to the US National Institutes of Health, and Rioux has not described any medical condition. For the wider science, see why NBA players are so tall.

Does Olivier Rioux have a medical condition?

No condition has been reported. Rioux has said doctors could only explain his height with his family’s genetics, and nothing he, his family or his teams have said points to anything else.

Olivier Rioux’s college career: Florida to UC Irvine

IMG Academy and recruiting

Rioux started playing at 5, spent time in Real Madrid’s youth program and finished high school at IMG Academy in Bradenton, Florida. He was a three-star recruit, reclassified from the class of 2025 to 2024, and committed to Florida in November 2023, joining as a preferred walk-on.

Florida, 2024-25: redshirt on a title team

Coach Todd Golden redshirted him after four games: “I’m just not trying to burn your year putting you in for 30 seconds.” Florida went on to win the 2025 NCAA championship; Rioux was on the roster but did not play.

Florida, 2025-26: the tallest player in college history

Rioux made his debut on 6 November 2025 against North Florida, entering with 2:09 left and becoming the tallest player ever to appear in a college game. His first basket was a dunk against Saint Francis on 17 December 2025, and he dunked again in the NCAA Tournament against Prairie View A&M on 20 March 2026. Season totals: 11 games, 16 minutes, 3-of-6 shooting, 7 points, 6 rebounds. Florida’s frontcourt of Alex Condon, Thomas Haugh and Rueben Chinyelu left little room.

UC Irvine, 2026-27

Rioux entered the transfer portal on 31 March 2026 and signed with UC Irvine on 30 April. The Anteaters went 23-12 in 2025-26 and won the Big West regular season. Coach Russell Turner: “Olivier is a high-character young man whose presence will elevate our team, our university, and our community.” He has three years of eligibility left.

His first games for the Anteaters came at the William Jones Cup in Taiwan in August 2026. Against Malaysia he scored 13 points on 6-of-6 shooting in an 87-55 win, and he had a double-digit rebounding game in pool play as UC Irvine went 7-1 and reached the final.

Does Olivier Rioux start for UC Irvine?

That will be settled once the season begins: the first home game on UC Irvine’s schedule is against Cal State LA on 27 October 2026, and the team has not named a starting lineup. The Jones Cup alone gave him more game action than two seasons at Florida. We expect a rotation role; how many minutes he earns is the most important number of his season.

The trend matters for his NBA case: his minutes fell from 18.8 a game at U16 to about 9 at U18 and U19 as the opponents got older and faster.

Will Olivier Rioux make the NBA?

Our honest estimate: about a 5% chance he ever plays in an NBA regular-season game. Here is the reasoning.

  • Against: no NBA scout or mainstream mock draft has projected him as a pick. He has played 16 college minutes in two seasons, and his international minutes shrank as the competition improved. Players this size have to show they can move well enough to defend in space, and he has not had the minutes to show it.
  • For: 7’9″ cannot be taught. Coaches describe him as coachable and improving; Golden said he had “flashes in practice where he’ll make some plays and you’re like, ‘Whoa.'” At UC Irvine he should get real minutes for the first time.
  • The path: Tacko Fall, 7’6″, went undrafted in 2019 and still played parts of three NBA seasons on two-way deals. That is the realistic model for Rioux: a big role in college, then a summer league or two-way chance.

Olivier Rioux NBA draft projection and eligibility

No mainstream 2027 mock draft or big board lists Rioux; none of the six we used for our 2027 NBA draft center rankings includes him. He is old enough to declare early for any draft, since he is past 19 and more than a year out of high school. If he stays at UC Irvine for all three of his remaining seasons, his college eligibility runs through 2028-29, which points to the 2029 draft. Any projection will depend on what he does with real minutes this season.
