A standard indoor volleyball court measures 18 meters (approximately 59 feet) in length and 9 meters (approximately 29.5 feet) in width

. These dimensions are consistent for official indoor play in FIVB, NCAA, and Olympic competitions. The court is divided into two equal halves by a centerline, and there is a minimum free zone of 3 meters (about 10 feet) around the court for player safety and movement

. For beach volleyball, the court is smaller, typically 16 meters by 8 meters (about 52.5 feet by 26.3 feet)

. In summary:

• Indoor volleyball court: 18 m (59 ft) long × 9 m (29.5 ft) wide
• Beach volleyball court: 16 m (52.5 ft) long × 8 m (26.3 ft) wide

These measurements ensure standardized play across most competitive volleyball formats
