Carlos Alcaraz is 183 cm tall — 6 ft 0 in — according to ATP's official player information. Among the current top four men's seeds for the 2026 US Open, that makes Alcaraz the shortest of the four, but the differences become much easier to understand when everyone is placed on the same baseline.
Alexander Zverev is the tallest in this comparison at 198 cm (6 ft 6 in). Félix Auger-Aliassime is 193 cm (6 ft 4 in), and Novak Djokovic is 188 cm (6 ft 2 in). From Alcaraz at 183 cm to Zverev at 198 cm, the full range is 15 cm.
Put another way, Zverev stands 15 cm taller than Alcaraz, Auger-Aliassime is 10 cm taller, and Djokovic is 5 cm taller. Those are noticeable differences on a true-scale lineup, even though ordinary match photos can exaggerate or hide them through camera angle, footwear and perspective.
The 2026 US Open gives the comparison a particularly clear frame. With Jannik Sinner out of the tournament, Zverev moves to the top seed, Alcaraz sits at No. 2, Auger-Aliassime at No. 3 and Djokovic at No. 4 in the current field. The four players therefore make a naturally bounded comparison rather than an arbitrary celebrity lineup.
Height does not decide a tennis match, and this comparison is not a ranking of athletic ability. It answers a simpler question visually: how tall is Carlos Alcaraz next to the other leading men's seeds when all four are shown at the same real-world scale?
