What is the regulation weight of a table tennis ball?
Answer
2.7 grams
The regulation weight of a table tennis ball is 2.7 grams.
This very light ball is paired with a standard diameter of 40 millimetres. Its low mass allows players to create major changes in speed, direction, and spin with relatively small racket movements. It also contributes to the sport’s rapid exchanges at close range.
Weight is only one requirement for an approved ball. The ball must be spherical, have a uniform bounce, and be made from an approved plastic material in modern competition. White and orange are the permitted colors, chosen so the ball can be seen clearly against the table and surrounding background.
The 2.7-gram figure should not be confused with the ball’s former 38-millimetre diameter. The diameter changed in 2000, but the standard weight remained 2.7 grams. This is why older and newer regulation specifications can differ on size while agreeing on weight.
