Rules
What should be weight of a standard table tennis ball?
Hi Arpit,
Here are the regulations about the ball in the ITTF Regulations.
THE BALL
The ball shall be spherical, with a diameter of 40mm.
The ball shall weigh 2.7g.
The ball shall be made of celluloid or similar plastics material and shall be white or orange, and matt.
Question actions
When the ball hits the ceiling the point is over. You must hit the ball directly back onto the table otherwise you lose the point. In International tournaments the roof needs to be at least 5 metres above the playing surface but in local competitions you might often encounter much lower ceilings.
