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).

Tennis balls are regulated by the International Tennis Federation (ITF) under Rule 3, with standard Type 2 pressurized balls having a diameter of 6.54–6.86 cm (2.57–2.70 in), weight of 56.0–59.4 g (1.975–2.095 oz), and a rebound of 135–147 cm (53–58 in) dropped from 2.54 m. Padel balls are governed by the FIP, sharing identical diameter (6.35–6.77 cm) but operating at lower internal pressure (11 psi / 4.6–5.2 kg/cm²) for a slightly slower rebound of 135–145 cm.
