What is the diameter of the ball used in table tennis?

  1. A.36 mm
  2. B.38 mm
  3. C.40 mm
  4. D.44 mm

Correct answer

C. 40 mm

Explanation

The correct answer is C, 40 mm. The International Table Tennis Federation enlarged the ball from 38 millimetres to 40 millimetres after the Sydney Olympics of 2000, so that the slower, more visible ball would make rallies easier to follow on television. The ball weighs 2.7 grams and is white or orange. Option B, 38 mm, is the old size and is the trap in this question, because it was the standard for decades and still appears in older books. Option A, 36 mm, and option D, 44 mm, are invented figures that have never been used. Remember one more change of the same period: celluloid balls gave way to plastic, or poly, balls from 2014, and the game itself was cut from 21 points to 11 in 2001, so the modern ball, the modern score and the plastic material all belong to the years after 2000.
