Footballs (Soccer balls) come in a series of successive sizes. The underlying reason for the variety of different soccer ball sizes is for the smooth and safe development of young players as they grow in skill and age. Set by the football federations around the world, using smaller ball sizes for younger players reduces the risk that the ball would hurt them during play. Matching the appropriate ball size to the age of the player is safer on a players body as they may injure their ligaments and tendons by kicking a larger ball before their body has matured. Compare the various sizes here to help determine which official football (soccer ball) size is right for you.
