Basketball vs. Volleyball
Comparing 2 standards across 18 specifications. 18 key differences identified.
Basketball dimensions and inflation pressures are standardized by FIBA, the NBA, and the NCAA. The official men's ball (Size 7) measures 29.5 in (74.9–78.0 cm) in circumference with a mass of 22 oz (567–650 g) and inflation pressure of 7.5–8.5 psi. The official women's ball (Size 6) measures 28.5 in (72.4–73.7 cm) with a mass of 18–20 oz (510–567 g).
Official volleyballs are regulated by the FIVB (Fédération Internationale de Volleyball). Indoor volleyballs have a circumference of 65.0–67.0 cm (25.6–26.4 in), mass of 260–280 g (9.2–9.9 oz), and inflation pressure of 0.30–0.325 kg/cm² (4.26–4.61 psi / 294.3–318.82 hPa). Beach volleyballs share identical circumference and mass but operate at lower pressure of 0.175–0.225 kg/cm² (2.49–3.20 psi).
