Roughly 22 cm (8.65 inches) in diameter for a regulation size 5 ball. Rules state that a size 5 ball must be 68 to 70 cm in circumference. Averaging that to 69 cm and then dividing by pi gives about 22 cm for a diameter.
The rules of the game state that the circumference should be 68 to 70 cm. (See e.g. <http://en.wikipedia.org/wiki/Football_(ball)#Dimensions>.)
Thus, the average *circumference* is probably 69 cm (about 27 1/6 in), making the diameter (69 / pi) cm, or roughly 22 cm (about 8 3/4 in).
Size 4s are 25-26 inches in circumference, weigh 12-13 ounces, and should be inflated to 9 PSI.
There is nothing in the rules stating the diameter of a ball, but the circumference must be between 68-70cm/27-28inches.
7.96" - 8.28"
5.73"- 8.28", diameter depends on size.
If the ball makes 12 rotations in 10 meters, then 1 rotation takes 83.3 cm. This would equal the circumference of the ball. Then the diameter would be 26.5 cm (or 10.43 inches). This is significantly larger than a regulation soccer ball, which must have a circumference between 68 and 70 cm.
A foot-skill ball is a small (usually four inches in diameter) bean filled ball. The idea is to train on a much smaller surface than a soccer ball to improve your touch. If you can dribble well and have a clean touch on a four ball, then a full size soccer ball should be no problem!
It isn't called soccer ball because the soccer ball is the ball you use in soccer. See? I have actually heard people call it soccer and soccer ball.

it is around the size 68-70 cm (about 27-28 inches) in diameter
Soccer balls, in their deflated form, can range from 50 feet in diameter to 60 feet. While in their inflated form, can range from 69 feet in diameter to 169 feet. Please call 1-800-824-4627 for more information on soccer balls and their counterparts.

Women's soccer is in a different league to the men's soccer. Women use a soccer ball that is the same size as the men's soccer ball.
