The International Table Tennis Federation increased the diameter of a regulation ball from 1.5 inches to 1.57 inches after the 2000 Olympics to make it easier to see on TV and slow down the game. This was the first official change to the game since 1937.
In an attempt to make table tennis more enjoyable for television audiences, the International Table Tennis Federation took action after the 2000 Summer Olympic Games in Sydney, Australia. To make the ball easier to see during the frenetic action, the diameter of a regulation table tennis ball was officially changed from 1.5 inches (38 mm) to 1.57 inches (40 mm). The sport’s governing body also hoped that the larger ball would increase air resistance and slow down the game slightly, making it easier for TV viewers to follow the fast-paced action. The decision to increase the ball’s diameter was also prompted players increasing the sponge layer on their paddles, which helped them put more zip on the ball.
