Soccer balls come in 3 different sizes: 3, 4, & 5. The ball size is shown on the ball. Also, look for a stamp that says either "official size & weight" or "FIFA Approved". Even if a ball is the official weight, some balls are heavier & harder than others. Don't get a ball that is too heavy or hard (some seamless balls are especially hard). Some balls are so hard that it is painful to kick them. If you have a choice, a shiny, waterproof surface is best because it won't absorb water & will last longer. Test the ball to see if it's round & will fly straight by tossing it into the air with a lot of spin on it to see if it wobbles. U-6 & U-8 use a size 3; U-10 & U-12 use a size 4; and U-13 & older use a size 5 ball.
