Conforming golf balls are regulated by the USGA and The R&A under the Rules of Golf Appendix III. A conforming golf ball must have a minimum diameter of 1.680 in (42.67 mm), a maximum weight of 1.620 oz (45.93 g), spherical symmetry, and an initial velocity not exceeding 250 ft/s (76.2 m/s) at 75 °F under standard test conditions.

Official table tennis balls are regulated by the International Table Tennis Federation (ITTF Handbook Rule 2.3). A tournament match ball has a diameter of 40.0–40.6 mm (designated as 40+ mm), weighs exactly 2.70 g (tolerance 2.67–2.77 g), and is manufactured from celluloid-free non-flammable plastic (ABS/poly-material). It must produce a rebound of 24.0–26.0 cm when dropped from 30.5 cm onto steel.
