Sizes
The standard ball size used in official FIFA matches and, in fact, most
soccer games around the world,The ball is 28 in (71 cm) in
circumference and weighs in between 14 and 16 oz (400-450g )Only
size ball to meet the requirements outlines in the Law 2 of the FIFA Laws of
the Game.
If the ball is too big, will affect the speed of the ball. If the ball is
too small, will affect player of the control of it
Materials
Polyurethane balls have become a huge hit in recent years because they are
relatively inexpensive, soft, provide a good touch, and resist water much
better.
Different material is made out of football, players have different feel to
it.
Weight
or any official match, the soccer ball needs to weigh between 14 and 16 oz (about 410 to 450 g ). For this reason, the only size ball that
can be used is the size 5.
Pressure
The inflatable bladder inside of the soccer ball is filled with air to
expand the panels and give the ball the spherical shape it needs. The
pressure inside of this bladder needs to be between 8.6 and 15.7 psi to ensure
the appropriate degree of firmness. After all, deflated balls neither
roll nor bounce properly!
The roles are very important with the game, because no roles, no fair. If
the game likes a chaos fight nobody want to see it.
