The utility ball (also known as a playground ball or named after the games in which it's used, such as dodgeball and kickball) is a spherical, inflated ball used in several kinds of playground games and sports. Utility balls were introduced in the mid-20th century and have continued to be used in various games.
History
[edit]The first dedicated utility balls were introduced by American manufacturer Voit shortly after World War II and became popular within a few years, being adapted to several games such as dodgeball and kickball that had previously been played with harder objects, like basketballs.[1] The softer ball was safer and easier to adapt to other games, such as four square.[2][3]

Utility balls are typically made of polyvinyl chloride or rubber and have a diameter of 8.5 inches (220 mm) and weigh between 11.6 to 13.3 ounces (330 to 380 g).[1] The balls are often made with ribbing for grip and are inflated to 2 pounds per square inch (14 kPa).[2]
