Reilly Opelka’s Stature Sparks Headlines at US Open

NEW YORK (August 26, 2025) - Reilly Opelka’s commanding presence on court has become a talking point at the 2025 US Open, with fans once again asking: How tall is Opelka?

Opelka, the 27-year-old American known for his booming serve, stands at 6 feet 11 inches - making him the joint-tallest player ever on the ATP Tour. His height, which he shares only with Ivo Karlović at the top of the rankings’ all-time list, was on full display Monday night at Arthur Ashe Stadium.

During his straight-sets loss to second seed Carlos Alcaraz, spectators were struck by the sheer size differential as Opelka loomed over his opponent at the net. “With [Reilly’s] serve, I couldn’t get the rhythm I wanted,” Alcaraz said after the 6-4, 7-5, 6-4 victory. However, he praised Opelka’s physical gifts, noting that his height lends an “incredible advantage” to his power game.

The US Open draw website highlights Opelka as “the tallest man competing in New York this year, one inch taller than fellow American John Isner and tied with Karlović as the tallest-ever ATP-ranked player.” His 6′11” frame not only makes for striking visuals but also fuels his reputation as one of the tour’s most formidable servers, regularly blasting aces over 140 mph.

As Opelka continues to harness his height on the world’s biggest stage, the question of “How tall is Opelka?” remains an enduring part of his growing legend.
