Stephon Castle height, weight and position
The official Stephon Castle height is 6 ft 6 in (198cm), and his listed weight is 215 lb (97kg), according to his NBA.com player page and Basketball Reference. That is big for a guard. Most point guards in the league stand between 6-1 and 6-4, so Castle can see over defences, finish through contact and switch onto forwards.
His position is listed as point guard and shooting guard. As a rookie he often played off the ball. Since 2025-26 he has been San Antonio’s main ball-handler, which explains the jump in his assist numbers. His strength and long arms also make him one of the better young defensive guards in the league.
