Official ping pong balls are slightly larger than table tennis balls. The name “ping-pong” was created by British manufacturer J. Jaques & Son in 1901, who also manufactured the first table tennis set. The name “ping-pong” then came to describe the game played using the Jaques’ equipment.
Later, the term “table tennis” was used to refer to both the sport and the equipment, and eventually, “ping-pong” became a trademark of Jaques & Son. Today, while “ping-pong” is commonly used as a synonym for table tennis, it is actually a trademarked brand name.
Official ping pong balls are slightly larger than table tennis balls. Ping pong = 3.7mm in diameter, while table tennis = 3.4mm diameter.
What is the ball in table tennis made of?
In 2014, the official material used in table tennis balls was changed from celluloid to plastic. Celluloid is a combustible compound made from nitrocellulose and camphor. However, it is also unstable and decomposes over time, causing the balls to lose their bounce.
In contrast, plastic balls are free of celluloid and are therefore more durable. In addition, they have a consistent bounce and resist changes in temperature and humidity. As a result, plastic table tennis balls are now the standard for competitive play.
