Ball: spherical, leather/synthetic, 65-67 cm circumference, 260-280 g, FIVB/Molten approved; Net: 2.24 m height (women's), 1 m wide × 9.5-10 m long; Antennas on each side of the net marking the legal crossing zone
Why people argue about this
People often assume that the exact size range for the ball (65-67 cm circumference) is more critical than the weight range (260-280 g), but actually, it's crucial to have a ball that meets both criteria approved by FIVB or Molten, as these specifications ensure consistent gameplay and fairness across all matches.
