​A rumor is circulating that Boston Celtics second-year center Amari Williams has gone from a listed height of 6-foot-11 to 7-foot-2. Obviously, that would be a major development—height is not something you can simply teach. Williams, a 2025 second-round pick, will be in Las Vegas for NBA Summer League as he continues to pursue establishing himself as an NBA-caliber contributor. The Celtics still have Neemias Queta on their roster, and they also signed Mitchell Robinson, so Williams might not be a central figure in the 2026-27 season. But if the growth proves real, his upside would become even more intriguing.
The challenge lies in determining how credible the growth claim is. The latest chatter comes from the website Heavy, which cites “reports” about the growth without providing a direct link to the original source. According to Heavy, Williams has apparently grown from roughly 6-foot-11 to around 7-foot-2 over the past year, with team staffers allegedly noting him towering over teammates in practice and confirming the growth spurts. A scan of X (formerly Twitter) around the offseason reveals fans discussing the possibility, though there isn’t an obvious, definitive source identifying where the initial report originated.
There isn’t a single, unmistakable source flashing “7-foot-2” for Williams. However, there is a more recent, official data point: the Celtics’ Summer League roster released in July lists Williams at 7 feet tall. That measurement is taller than his height listed out of college, and he already carried an impressive 7-foot-5 wingspan at the time. Until further confirmation emerges, it seems reasonable to treat Williams as a 7-footer, albeit one whose exact height—whether 7-foot-0 or 7-foot-2—remains subject to verification.
For those tracking Celtics developments, the team has also released several updates and rosters in the Summer League lead-up, and fans will be watching to see whether Williams’ height claim translates into on-court advantages or simply remains a tall tale. As with any such rumor, it’s prudent to rely on official measurements and verified sources before drawing firm conclusions about a player’s height or its impact on his NBA trajectory.
