What are the lines on a ping pong table for? The playing surface shall be uniformly dark colored and matt, but with a white side line, 2cm wide, along each 2.74m edge and a white end line, 2cm wide, along each 1.525m edge. These lines are referred to as “boundary lines” and therefore any ball landing outside and beyond their limits are “out of bounds”.
