Comparing 2 standards across 15 specifications. 15 key differences identified.
Official American footballs are governed by the NFL and NCAA rulebooks. The pro/college ball (Size 9) features a prolate spheroid shape with a long axis of 11.0–11.25 in (27.9–28.6 cm), long circumference of 27.75–28.5 in (70.5–72.4 cm), short circumference of 20.75–21.25 in (52.7–54.0 cm), weight of 14.0–15.0 oz (397–425 g), and inflation pressure of 12.5–13.5 psi.
Official ice hockey pucks are regulated by the National Hockey League (NHL Rule 13) and the International Ice Hockey Federation (IIHF). A regulation puck is made of vulcanized rubber measuring exactly 3.0 in (7.62 cm) in diameter, 1.0 in (2.54 cm) in thickness, and weighing 5.5–6.0 oz (156–170 g). Game pucks are frozen for several hours prior to gameplay to eliminate surface bounce.
