Table Tennis Balls (Ping pong balls) are spherical polymer balls fabricated specifically for the sport. Ping pong balls are colored as either white or orange depending on the table surface and game style. White balls are official tournament balls and pair well with blue or green tables, while orange balls are used for casual games as they are easier to see in most settings.

Table tennis balls are rated with a star system to denote quality—one star being the softest and easiest to break while three stars is the most durable and approved for tournament play. The official table ping pong ball has changed over the years from a composition of celluloid to polymer and from a size of 1.5” (38 mm) to 1.57” (40 mm).
