Contrary to popular belief, the futsal ball is not heavier than a soccer ball. Futsal Online's Tim Sheldon explains:
"According to FIFA, the inspected weight of a Size 5 ball is 410 - 450 grams. The inspected weight for a Size 4 Futsal ball is 400 - 440 grams. The minimum and maximum inspected weights of a Futsal ball are therefore 10 grams lighter than the outdoor ball.
In order to assess bounce, the balls are dropped ten times onto a steel plate from a height of two metres, under controlled temperatures, according to FIFA.
The FIFA chart indicates that the Size 5 ball has a bounce (rebound) of 125 - 155 cm, while the Futsal ball has a bounce of 50 - 65 cm.
Comparing the minimums, we see that the bounce of the Futsal ball is only 40 percent of the bounce of the Size 5. This means the Futsal ball has 60 percent less bounce than the Size 5.
Therefore, we can say that according to FIFA specifications the Futsal ball is a size smaller and 10 grams lighter than the outdoor ball and has 60 percent less bounce."
