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.
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.

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, a former volleyball player, is 6’8″; his mother is 6’1″ or 6’2″ depending on the source; 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.
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.

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.
Draft timing: under the NBA’s rules he is already old enough to declare early for any draft. If he plays out his three remaining college seasons, he would become automatically eligible in 2029 (our estimate, based on his eligibility).
