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.
