The only thing that matters is the soccer ball size on game day. For younger soccer players ages 4-6, I think the main reason a size 3 is better is because they can roll it easier. For them rolling a size 4 is like an adult trying to roll as basketball size.
Several years ago, in the year I became eligible for Medicare and was officially certified as an elderly person, I discovered the joy and challenge of juggli...
Soccer ball size corresponds to player age, but ball size for youth soccer leagues can differ by location and league standards—we recommend confirming ball size with your league or association. In general, here are the appropriate sizes for age groups: Size 5 (Adult/Professional): U12 and up (ages 12 and older), 27-28 in/68-70 cm circumference. Size 4 (Youth): U8-U12 (ages 8-12), 25-26 in/63.5-66 cm circumference.
SIZE 1. Also referred to as “minis,” size 1 soccer balls have a circumference of 18″-20″. While some may benefit from skill training with these sized soccer balls, their main purpose is for general entertainment and collection. Many souvenir balls with player logos or club designs will be size 1 for their ease and collectability. Finding the right soccer ball size based on age group can be beneficial, but remember that size can also vary by league standards.
Yes. Here is a good reference guide for quality issues! However, until your child needs a size 5, I wouldn't worry about it. In my opinion, cheaper is better for the younger ages as long as it meets the size & color requirements.
In addition to having an impact on speed and trajectory, the size and mass of balls also contribute to how external forces affect them. When two balls of the same diameter are made of materials of different density and mass, the ball with the greater mass-density will travel farther if projected with the same amount of force, or at the same initial speed.
Indoor soccer balls are most often size 5, but are made to have less rebound to accommodate the harder surfaces and turf that covers the playing ground and walls of an indoor soccer field. Beach soccer balls are size 5, but are lighter than an official grass soccer ball, and typically softer to provide more comfort to bare feet. They are usually brightly colored to make them easier to see on the sandy beach terrain, and often are made water resistant in case they are kicked into the ocean.
Ball size can determine how much monogamy exists in a species. Ball size, relative to body weight, can help researchers determine how much monogamy or promiscuity exists in a species, though not an individual (sigh). Consider a chimpanzee: Hugh balls. Relatively small body size.
